    Before: SRINIVASAN, Circuit Judge, and EDWARDS and
    RANDOLPH, Senior Circuit Judges.
    Opinion for the Court filed by Circuit Judge SRINIVASAN.
    SRINIVASAN, Circuit Judge: In 2018, the National
    Transportation Safety Board revoked the air agency certificate
    held by Kornitzky Group. The certificate authorized Kornitzky
    Group to operate as a repair station that performs maintenance
    on bearings used in jet engines. The Board revoked Kornitzky
    Group’s certificate based on two distinct set of allegations.
    First, the Board found that Kornitzky Group had violated
    aviation safety regulations by repairing engine bearings
    without technical data necessary to ensure it was conducting
    the repairs properly. Second, the Board determined that
    Kornitzky Group intentionally falsified maintenance records
    by representing only that it had inspected the engine bearings
    without indicating that it had also disassembled and repaired
    them.
    Kornitzky Group seeks review of the Board’s decision.
    We uphold the Board’s determination concerning Kornitzky
    Group’s performance of maintenance without the appropriate
    technical data.         But we set aside the Board’s
    intentional-falsification charge because the Board departed
    from its own precedents when considering whether Kornitzky
    Group had acted with the requisite knowledge. We thus vacate
    the Board’s revocation of Kornitzky Group’s air agency
    certificate.

    I.
    A.
    Kornitzky Group, LLC, was founded in 2010 by two
    engineers, Michael Kornitzky, who has since passed away, and
    Zev Galel. The company performed maintenance on turbine
    engine bearings used in jet engines. The bearings are structural
    components of an engine that connect other components and
    minimize friction, enabling the engine to function as designed.
    In August 2011, the FAA issued Kornitzky Group an air
    agency certificate, which authorized the company to inspect
    and clean turbine engine bearings. Between 2011 and 2012,
    Kornitzky Group applied for and received additional ratings
    allowing it to perform repairs on engine bearings in accordance
    with a military specification it presented to the FAA. With the
    additional ratings, the company not only could inspect and
    clean bearings, but also could disassemble bearings, clean and
    polish their parts, reassemble the bearings, and then certify
    them for return to service.
    In December 2015, Gary Watson, an FAA Principal
    Maintenance Inspector, conducted a three-day inspection of
    Kornitzky Group, during which Watson “did not find any
    discrepancies or anomalies.” Letter from Gary M. Watson to
    Zev Galel (Dec. 14, 2015), J.A. 140. Nine months later, the
    FAA received two complaints about the technical data used by
    Kornitzky Group to conduct repairs. The complaints prompted
    the agency’s Flight Standards District Office to forward the
    proposed repair data provided by Kornitzky Group in 2012—
    i.e., the military specification—to the agency’s Engine
    Certification Office. The Certification Office determined that
    Kornitzky Group’s data was not specific enough to support the
    repair of turbine engine bearings.
    4
    On March 24, 2017, Darren Pittacora, who had replaced
    Watson as the FAA’s Principal Maintenance Inspector for
    Kornitzky Group, sent the company a letter advising that the
    agency had incorrectly issued one of Kornitzky Group’s ratings
    in 2012, in part because the District Office had not forwarded
    the proposed data to the Certification Office for review. The
    letter advised Kornitzky Group that it had 10 days to submit to
    reinspection under 49 U.S.C. § 44709 or face suspension of its
    license.
    In May 2017, Pittacora and Dr. Chip Queitzsch, the FAA’s
    Chief Scientific and Technical Advisor for Engine System
    Dynamics, among other officials, conducted the reinspection.
    On March 1, 2018, the FAA notified Kornitzky Group that the
    results of the reinspection were unsatisfactory because the
    company had exceeded the scope of work permitted by the
    original equipment manufacturer (OEM) and the relevant
    military specification.
    That same day, the FAA issued an emergency order
    revoking Kornitzky Group’s air agency certificate. The order
    rested on two distinct sets of alleged violations. First, the FAA
    alleged that, by disassembling and repairing engine bearings
    without the requisite technical data, Kornitzky Group had
    violated several maintenance regulations (namely, 14 C.F.R.
    §§ 43.13(a), 145.201(b), 145.201(c)(1), and 145.201(c)(2)).
    Second, the FAA alleged that Kornitzky Group had
    intentionally falsified statements in its repair station records
    when approving bearings for return to service, in violation of
    14 C.F.R. § 145.12(a). The intentional-falsification charge
    related to four work orders documented on an FAA form, Form
    8130-3. The FAA contended that Kornitzky Group had
    indicated on the Form 8130-3 only that it had inspected engine
    bearings without indicating the other work it had performed in
    5
    connection with the bearings (e.g., disassembly, polishing, and
    reassembly).
    B.
    In April 2018, an administrative law judge from the
    National Transportation Safety Board, an independent agency
    that adjudicates FAA enforcement actions, conducted a four-
    day evidentiary hearing. The FAA presented Pittacora and
    Queitzsch as its primary witnesses, with Queitzsch testifying
    as an expert. Kornitzky Group presented Galel, the company’s
    sole principal, and Emanuel Branzai, its own expert.
    The administrative law judge first found that Kornitzky
    Group had violated each of the maintenance regulations
    because the company was unable to produce the technical data
    that supported its additional ratings for disassembly and repair
    of bearings. The administrative law judge rejected the
    intentional-falsification claim, however, because Pittacora
    testified that Kornitzky Group’s statements on the Form
    8130-3s were not false when examined alone. The judge thus
    determined that the appropriate sanction was to suspend
    Kornitzky Group’s certificate pending compliance, rather than
    permanently revoke it.
    Both Kornitzky Group and the FAA appealed to the Board.
    See Elwell v. Kornitzky Grp., LLC, NTSB Order No. EA–5840,
    
    2018 WL 2733940
    (May 11, 2018) [hereinafter Board
    Decision]. The Board affirmed the administrative law judge’s
    conclusion that Kornitzky Group had violated the maintenance
    regulations by conducting disassembly and repair of bearings
    without the necessary technical data. 
    Id. at *10–11.
    The
    Board, though, reversed the administrative law judge with
    regard to the intentional-falsification claim, ruling that the
    FAA had proved that charge. 
    Id. at *7–10.
                                   6
    The Board found that Kornitzky Group’s selective
    disclosure of information rendered the Form 8130-3s false
    because the company had excluded other information in a way
    that gave an incomplete and misleading impression of the work
    it had performed. The Board further found that the company
    acted with knowledge of that falsity. 
    Id. The Board
    decided
    that the intentional-falsification charge warranted revocation of
    Kornitzky Group’s certificate because it called into question
    the company’s “care, judgment, and responsibility.” 
    Id. at *12
    (citation omitted).
    II.
    We sustain a Board decision unless it is “arbitrary,
    capricious, an abuse of discretion, or otherwise not in
    accordance with law.” Dickson v. NTSB, 
    639 F.3d 539
    , 542
    (D.C. Cir. 2011) (quoting 5 U.S.C. § 706(2)(A)). Kornitzky
    Group seeks a reinstatement of its air agency certificate,
    arguing that the Board acted arbitrarily and capriciously in
    finding violations of the FAA’s maintenance and
    intentional-falsification regulations. We uphold the Board’s
    determination that Kornitzky Group violated the FAA’s
    maintenance regulations, but we set aside the Board’s finding
    that the company intentionally falsified its entries on FAA
    Form 8130-3. We therefore vacate the Board’s revocation of
    the company’s air agency certificate.
    A.
    The Board determined that Kornitzky Group’s repairs
    violated certain FAA maintenance regulations: 14 C.F.R
    §§ 43.13(a), 145.201(b), 145.201(c)(1), and 145.201(c)(2).
    Section 43.13(a) requires that each person performing
    maintenance must “use the methods, techniques, and practices
    prescribed in the current manufacturer’s maintenance
    7
    manual . . . or other methods, techniques, and practices
    acceptable to the Administrator.” 
    Id. § 43.13(a).
    The remaining regulations impose requirements pertaining
    to “technical data.” Technical data refers to the engineering
    drawings and specifications “needed to define the
    configuration and design features” of aircraft engines,
    including the dimensions necessary to determine the
    airworthiness of any altered or repaired aircraft article. Fed.
    Aviation Admin., Collins Interpretation, 
    2011 WL 1459993
    , at
    *2 (Apr. 8, 2011). Section 145.201(b) provides that a
    “certificated repair station . . . may not maintain or alter any
    article for which it is rated if it requires special technical
    data . . . that are not available to it.” 14 C.F.R. § 145.201(b).
    Section 145.201(c)(1) similarly establishes that a “certified
    repair station may not approve for return to service” any article
    that is repaired without acceptable technical data. 
    Id. § 145.201(c)(1).
    And § 145.201(c)(2) parrots § 145.201(c)(1),
    except that it requires pre-approved (rather than acceptable)
    technical data for a “major repair or major alternation.” 
    Id. § 145.201(c)(2).
    The Board reasonably determined that Kornitzky Group
    violated each of those regulations. During the reinspection, the
    FAA’s inspection officials asked Kornitzky Group about the
    process it used for inspecting and repairing bearings. For each
    of the work orders at issue in this case, Kornitzky Group
    disassembled the bearing to inspect its parts with a stylus or
    scribe, looking for scratches, dents, pits, or depressions. In
    each instance, the bearing failed the initial inspection because
    it exhibited signs of burnishing, pitting, staining, or scratching.
    Kornitzky Group then polished and “lapped” the bearing parts
    (i.e., used an abrasive to smooth the parts’ surfaces) to remove
    the imperfections and then reassembled the bearing. That
    process necessarily removes material from the bearing.
    8
    By performing those functions, Kornitzky Group came
    into conflict with the maintenance regulations. First, the
    pertinent OEM manuals for the bearings prohibited
    disassembly, which means Kornitzky Group’s maintenance
    procedures violated § 43.13(a) unless it had other “acceptable”
    maintenance procedures, which it did not. Second, Kornitzky
    Group had no way to determine whether the amount of bearing
    material it removed sufficed to jeopardize the bearings’
    airworthiness because it had no access to the appropriate
    technical data, in violation of the § 145.201 regulations. The
    company could not produce the technical data because the data,
    according to the company, was stored in a computer once
    owned by its founder Mike Kornitzky and no longer in the
    company’s possession.
    Kornitzky Group now argues that the military
    specification cited in its ratings fulfills the requirements of
    § 145.201 and § 43.13(a). With regard to § 145.201, however,
    the military specification does not itself contain the kind of
    substantive technical data required by that provision. Instead,
    the specification incorporates OEM technical data, stating:
    “The need for maintaining the latest technical data in a readily
    available state cannot be overemphasized. It shall be the
    responsibility of the bearing shop . . . to obtain all drawings
    pertaining to bearings prior to induction in the shop for
    processing.” Military Specification T.O. 44-B-1-122, Ex. A-
    33, R. 1366. Because the military specification relies on the
    possession of OEM technical data—which the company does
    not possess—the Board appropriately determined that the
    military specification did not itself satisfy § 145.201.
    With regard to § 43.13(a), Kornitzky Group is correct that
    the FAA approved use of the military specification when it
    issued the company’s additional ratings in 2012. But
    Kornitzky Group did not perform the work in accordance with
    9
    the specification. The specification requires maintenance
    providers to compare repaired bearings to tolerance drawings,
    which Kornitzky failed to do. Also, the military specification
    provides it is “only to be used on bearings designed to be
    completely disassembled. The bearing drawing or the original
    component technical manual should specify that the rolling
    elements are removable.”         Military Specification T.O.
    44-B-1-122, Ex. A-30, R. 1363. But the OEM manuals of the
    bearings repaired by Kornitzky Group indicate the opposite,
    that the bearings should not be disassembled. Therefore, even
    if the military specification may be, in a vacuum, an
    “acceptable” alternative method under § 43.13(a), Kornitzky
    still violated that regulation by failing to comply with the
    specification when performing its work.
    That leaves one narrow argument advanced by Kornitzky
    Group, pertaining solely to § 145.201(c)(2). That regulation,
    as noted, prohibits returning an article to service after a “major
    repair” unless the repair was performed in accordance with pre-
    approved technical data. Kornitzky Group argues that its
    maintenance functions did not qualify as “major repairs.” The
    Board reasonably concluded otherwise.
    A major repair is any repair “[t]hat, if improperly done,
    might appreciably affect weight, balance, structural strength,
    performance, powerplant operation, flight characteristics, or
    other qualities affecting airworthiness.” 14 C.F.R. § 1.1. At
    the hearing, the FAA’s witnesses testified that Kornitzky
    Group’s repairs could affect the bearing’s airworthiness:
    “Anytime that you change the characteristics of the bearing that
    affect its life and its load-carrying capability [as Kornitzky
    Group did], you introduce the potential for the bearing to fail
    in service when it shouldn’t, and that means loss of the engine,
    loss of thrust. You change the performance characteristics of
    the aircraft, and it puts you at risk of an accident.” Hearing Tr.
    10
    359, J.A. 187. Additionally, another regulation provides an
    illustrative list of major repairs, including “[s]pecial repairs to
    structural engine parts by welding, plating, metalizing, or other
    methods” as a type of “powerplant major repair[].” 14 C.F.R.
    part 43, App. A(b)(2)(iii). And the FAA’s witnesses testified
    at the hearing that bearings were “structural engine parts.”
    Hearing Tr. 29–30, R. 216–17. What is more, Kornitzky Group
    contracted to have “plating” performed on two of the four
    bearings.
    Kornitzky Group points to an FAA staff manual, which
    does not specifically list engine bearings as a structural engine
    part or as a “main section[]” of an engine. See FAA Order
    8900.1, Vol. 4, Ch. 14, Sec. 12, ¶¶ 4-1622, 4-1623. But
    Kornitzky Group did not rely on the staff manual before either
    the administrative law judge or the Board, meaning we are
    restricted from reviewing the argument absent good cause,
    which Kornitzky Group has not established. 49 U.S.C.
    § 1153(b)(4); see Gorman v. NTSB, 
    558 F.3d 580
    , 591 (D.C.
    Cir. 2009). In any case, the cited provisions of the manual are
    illustrative and do not purport to establish exhaustive lists of
    either major repairs or structural engine parts. In the end, the
    record adequately supports the Board’s finding that Kornitzky
    Group’s repairs fall within the FAA’s regulatory definitions of
    major repairs.
    B.
    Kornitzky Group next challenges the Board’s finding of
    intentional falsification. The relevant regulation, 14 C.F.R.
    § 145.12(a)(1)(ii), prohibits making any “intentionally false
    entry” in maintenance records. The three elements of an
    intentional-falsification charge are: (i) a false representation;
    (ii) in reference to a material fact; (iii) made with knowledge
    of its falsity. See Hart v. McLucas, 
    535 F.2d 516
    , 519 (9th Cir.
    11
    1976). Although we affirm the Board’s finding of material
    falsity for purposes of the first two elements, we conclude with
    regard to the third element that the Board failed to make a
    finding of subjective knowledge as required by its own
    precedent.
    1.
    The Board alleged that Kornitzky Group intentionally
    falsified entries on four Form 8130-3s. In those forms, the
    company certified bearings as airworthy and authorized their
    return to service. Box 11 of the form is titled “Status/Work”
    and allows space for a short description of the maintenance
    conducted.       FAA Form 8130-3s, Authorized Release
    Certificates, J.A. 68, 87, 106, 123. On each form, Kornitzky
    Group completed Box 11 with an entry stating:
    “OVERHAULED.” 
    Id. Box 12
    of Form 8130-3, entitled “Remarks,” contains
    space for more extensive comments. Agency guidance
    provides further direction about Box 12: “Describe the work
    identified in Block 11 and associated results necessary for the
    user or installer to determine the airworthiness of the product
    or article in relation to the work being certified.” FAA Order
    8130.21H, § 3-6(l). On one of the four forms, Kornitzky Group
    wrote in Box 12, in relevant part, “Work performed [in
    accordance with OEM manual] CFM56-7B ESM,
    CFMI-TP-SM.10, Bearing Inspection Section 72-09-01. Rev.
    55, Dated 15JAN2017 and other data acceptable to or approved
    by the FAA. Work performed met the overhaul requirements
    [in accordance with] Part 14 C.F.R § 43.2.” FAA Form 8130-
    3, Authorized Release Certificate, Work Order 107750 (May
    12, 2017), J.A. 106. The other forms contain essentially that
    same entry but substitute the appropriate OEM manual for the
    particular bearing at issue.
    12
    Kornitzky Group’s Box 12 entries were reasonably
    deemed to have been false in two ways. First, a fair
    interpretation of Kornitzky Group’s entry “Work performed [in
    accordance with OEM] CFM56-7B ESM, CFMI-TP-SM.10,
    Bearing Inspection Section 72-09-01” is that the company’s
    repairs complied with the manufacturer’s guidelines. But
    while the company adhered to the referenced inspection section
    of the OEM manual, other sections of the manual prohibit
    disassembly of the bearings, yet Kornitzky Group
    disassembled each bearing at issue. The Board thus reasonably
    concluded that Kornitzky Group’s representation was false,
    and materially so, in that it was “capable of influencing a
    decision of the FAA inspector.” Thunderbird Propellers, Inc.
    v. FAA, 
    191 F.3d 1290
    , 1296 (10th Cir. 1999) (internal
    quotation marks omitted).
    Second, Kornitzky Group cited only the inspection section
    of the OEM manual. Each OEM manual, though, also has a
    separate section addressing repair, refurbishment, and overhaul
    of bearings. Kornitzky Group failed to cite those sections even
    though it not only inspected the bearings, but also repaired
    them. The Board reasonably determined that the company, by
    omitting any reference to the repair section and only citing the
    inspection section, failed to “[d]escribe the work . . . necessary
    for the user or installer to determine the airworthiness of the
    product or article,” as required by Box 12. FAA Order
    8130.21H, § 3-6(l).
    Granted, certain clues on the certification forms suggest
    that Kornitzky Group did more than inspect the bearings. Box
    11 notes that the bearings were overhauled, and each Box 12
    entry notes that the “[w]ork performed met the overhaul
    requirements” of 14 C.F.R. § 43.2. FAA Form 8130-3s,
    Authorized Release Certificates, J.A. 68, 87, 106, 123. But
    clues are not enough: as the Board explained, customers
    13
    assume that repair records are “scrupulously accurate,” and the
    certifications here, the Board permissibly concluded,
    “provide[d] a false sense of confidence in the maintenance
    work performed.” Board Decision at *7–8.
    In that respect, the Board’s decision was substantially
    supported by the testimony of Pittacora, the FAA’s principal
    inspector for Kornitzky Group. He explained that, even if
    portions of the Box 12 entry were true, the entry was materially
    false because it misled customers: “[T]he reason I think it’s
    false and intentional is because . . . there’s lot of work that gets
    done there that’s not documented on there, that the end user
    should be made aware of to make a reasonable assumption of
    airworthiness prior to installing it in a large turbo engine.”
    Hearing Tr. 420, J.A. 195. The agency’s conclusion that
    Kornitzky Group made materially false entries in documenting
    its critical aircraft maintenance functions thus was not
    arbitrary.
    It bears noting that the regulations include a provision
    addressing material omissions in addition to the one addressing
    material falsifications. See 14 C.F.R. § 145.12(b). We have no
    occasion here to address the precise interrelationship between
    those provisions, and we do not suggest that every material
    omission under § 145.12(b) necessarily amounts to a material
    falsification under § 145.12(a). But there is also no reason to
    assume that the regulations occupy mutually exclusive ground.
    See Lorenzo v. SEC, 
    139 S. Ct. 1094
    , 1102 (2019). For present
    purposes, it is enough to conclude that Kornitzky Group’s
    entries on Form 8130-3 were incomplete in a manner
    reasonably found to have been materially false.
    In sum, the FAA required Kornitzky Group to disclose any
    maintenance affecting the airworthiness of the bearings. The
    Board permissibly concluded that Kornitzky Group made a
    14
    materially false representation by referencing some but not all
    of its work affecting the bearings’ airworthiness.
    2.
    While we sustain the Board’s finding of material falsity,
    we cannot sustain the Board’s conclusion that Kornitzky Group
    acted knowingly. Under its own precedent, the Board was
    required to find that Galel, Kornitzky Group’s owner and sole
    principal, correctly understood the Form 8130-3 requirements
    but still instructed his company to provide a false response.
    Galel’s subjective knowledge, however, was not addressed by
    the administrative law judge and the Board did not make the
    required factual finding. As a result, we must vacate the
    Board’s intentional-falsification charge.
    Our starting point is our decision in Dillmon v. NTSB, 
    588 F.3d 1085
    (D.C. Cir. 2009). Jack Dillmon applied to the FAA
    for a medical certificate enabling him to become a pilot. 
    Id. at 1087.
    One of the questions on the form asked whether Dillmon
    had any “[h]istory of nontraffic conviction(s) (misdemeanors
    or felonies).” 
    Id. (alteration in
    original) (quoting FAA Form
    8500-8). Dillmon answered no, even though he had recently
    been convicted of felony bribery. The FAA charged him with
    intentional falsification. 
    Id. at 1088.
    The administrative law
    judge credited Dillmon’s testimony that he thought the
    question covered only drug- or alcohol-related offenses. 
    Id. at 1088–89.
    The Board reversed the administrative law judge
    because Dillmon “clearly knew that he had been convicted of
    a non-traffic offense,” notwithstanding Dillmon’s testimony
    that he misunderstood the question. 
    Id. at 1093
    (internal
    quotation marks omitted).
    We reversed the Board because it had deviated from its
    own precedent. Citing Administrator v. Reynolds, NTSB Order
    15
    No. EA-5135, 
    2005 WL 196535
    (Jan. 24, 2005), we held that
    Board precedent “require[d] the FAA to prove the airman
    subjectively understood what the question meant.” 
    Dillmon, 588 F.3d at 1094
    . By relying only on Dillmon’s knowledge of
    his conviction, we concluded, the Board’s analysis had skipped
    the necessary step of determining whether Dillmon understood
    that the form required him to disclose the conviction. See 
    id. We have
    consistently enforced that principle. In Singleton
    v. Babbitt, 
    588 F.3d 1078
    , 1085 (D.C. Cir. 2009), for instance,
    we reversed the Board’s revocation of a pilot’s license on an
    intentional-falsification charge where the pilot had no
    opportunity to testify about his understanding of the relevant
    question. And in Manin v. NTSB, 
    627 F.3d 1239
    , 1244 (D.C.
    Cir.    2011),      we     again    reversed    the    Board’s
    intentional-falsification charge because the Board had failed to
    consider testimony that the pilot did not think the
    medical-certificate application required him to disclose his
    disorderly conduct convictions.
    The Board of course is free to change course and depart
    from its own precedents if it stays within the bounds of its
    statutory authority. But the agency must recognize it is doing
    so and provide a reasoned justification. Without such an
    explanation, we have no way of ensuring that the Board’s
    “policies and standards are being deliberately changed, not
    casually ignored.” NLRB v. CNN Am., Inc., 
    865 F.3d 740
    , 751
    (D.C. Cir. 2017) (internal quotation marks omitted).
    There is no indication that the Board intends to abandon
    its subjective-knowledge requirement. To the contrary, the
    Board has applied that requirement not only in medical cases
    like Dillmon but also in mechanic cases like this one. In Acting
    Administrator v. Reynolds, NTSB Order No. EA-5641, 
    2012 WL 5954694
    (Oct. 25, 2012), the Board recognized that
    16
    “credibility findings from . . . law judges are necessary in
    intentional falsification cases, because the Board must consider
    a respondent’s subjective understanding of questions on
    medical certificate applications.” 
    Id. at *4.
    The Board found
    that approach equally “applicable in . . . mechanic logbook
    falsification case[s]” and relied upon it to reject an
    intentional-falsification charge brought by the FAA. 
    Id. Here, Galel’s
    testimony suggests that he believed Box 12
    only required Kornitzky Group to disclose the final inspection,
    not the work preceding it. He testified that the Form “8130 is
    not intended to have all of the information in block 12. It’s
    supposed to show of the information, representative
    information, sufficient information. And there’s no—the word
    of divulging does not—cannot be contained in that small block
    12. If I had to divulge everything that I did, I would have to
    put all of this in every block 12.” Hearing Tr. 654, J.A. 215.
    He continued, “the block 12 on the 8130s does not require the
    total list of everything that we use to perform the maintenance.”
    
    Id. In the
    context of Galel’s testimony to that effect, the Board
    could not find the subjective-knowledge standard satisfied
    without also finding Galel’s testimony to be non-credible. But
    the administrative law judge made no such determination
    (because he concluded the entries on the forms were not false).
    When the Board overturned the administrative law judge’s
    falsity finding, then, it should have remanded the case to the
    administrative law judge to make the credibility determination
    required by its precedents.
    The Board did not follow that course. Instead, it
    “expressly expand[ed] the Board’s ‘willful disregard’ standard
    from Administrator v. Boardman, Administrator v. Cooper,
    and Administrator v. Taylor.” Board Decision at *10
    17
    (footnotes omitted). Under that standard, when “an airman
    intentionally chooses not to carefully read the question for
    which he is providing an answer that he certifies by his
    signature to be true, a factfinder can infer ‘actual knowledge’
    from a willful disregard for truth or falsity.” Cooper v. NTSB,
    
    660 F.3d 476
    , 484 (D.C. Cir. 2011).
    In Boardman, for example, the applicant testified, “I did
    not read [the question]. I just glanced over it.” Acting
    Administrator v. Boardman, NTSB Order No. EA-4514, 
    1996 WL 748190
    , at *2 (Dec. 20, 1996). In Cooper, the applicant
    “admitted that it was a ‘big mistake’ to fail to read the question,
    and that, if he had read it, he would have answered ‘Yes.’”
    Administrator v. Cooper, NTSB Order No. EA-5538, 
    2010 WL 3358808
    , at *2 (Aug. 18, 2010). And in Taylor, similarly, the
    applicant admitted he “chose not to read any of the 25
    items . . . contained within question 18 . . . [and] testified had
    he read the question, he would have checked ‘yes.’” Acting
    Administrator v. Taylor, NTSB Order No. EA-5611, 
    2012 WL 158766
    , at *3 (Jan. 9, 2012).
    In this case, by contrast, there was no testimony about how
    closely Galel had read Form 8130-3. Nor does the form itself
    give us reason to assume Galel willfully disregarded its
    instructions. The form simply provides a place for “Remarks”
    and says nothing else. FAA Form 8130-3s, Authorized Release
    Certificates, J.A. 68, 87, 106, 123. And the FAA’s guidance
    about the form, which instructs a repair station only to describe
    any work necessary to determine airworthiness, does not solve
    the problem. See FAA Order 8130.21H, § 3-6(l). Galel could
    have reasonably (even if incorrectly) assumed that disclosing
    the final OEM inspection is all that is needed to determine
    airworthiness, especially given that Kornitzky Group had
    passed prior Administration inspections that way.
    18
    In short, the Board identified no evidence that Galel had
    intentionally disregarded the Form 8130-3 instructions, and the
    Board thus could not rely on any “willful disregard” principle
    to satisfy the subjective-knowledge standard required by its
    precedents. The Board’s departure from its precedent falls
    short of reasoned decision-making. See Ramaprakash v. FAA,
    
    346 F.3d 1121
    , 1124–25 (D.C. Cir. 2003).
    The FAA observes that the Board can set aside an
    administrative law judge’s findings as arbitrary and capricious,
    reweigh the evidence, and make its own factual findings, as
    long as the new findings are supported by substantial evidence.
    See 
    Dillmon, 588 F.3d at 1095
    . That may be true, but here, the
    administrative law judge never determined whether Galel
    subjectively understood the requirements of Form 8130-3. See
    Board Decision at *9, *22. And in any event, we can affirm
    the Board’s decision only on the grounds upon which it acted:
    Galel’s alleged willful disregard for the instructions. See SEC
    v. Chenery Corp., 
    318 U.S. 80
    , 87–88 (1943). On that score,
    the Board nowhere in its decision purported to reweigh the
    evidence and find that Galel subjectively understood the Box
    12 requirements. The Board concluded only that “[t]he
    evidence taken together suggests that [Galel] knew the
    information provided on the forms in question was not
    complete.” Board Decision at *10. That is no different than
    the Board’s argument in Dillmon that Dillmon had acted
    knowingly because he “knew he had been convicted of a
    non-traffic offense.” 
    Dillmon, 588 F.3d at 1093
    (internal
    quotation marks omitted). The argument failed then, and it
    fails again today.
    C.
    Our vacatur of the Board’s intentional-falsification finding
    requires us to vacate the Board’s revocation of Kornitzky
    19
    Group’s air agency certificate. FAA guidance allows for two
    types of remedial sanctions: (i) revocation, and (ii) indefinite
    suspension pending compliance. FAA Order 2150.3B at 7-1 to
    7-3. Revocation is appropriate when the FAA determines that
    the individual or company “lacks the qualifications to hold the
    certificate,” such as when its conduct demonstrates “a lack of
    the degree of care, judgment, or responsibility” required of a
    certificate holder. 
    Id. at 7-2.
    Meanwhile, indefinite suspension
    pending compliance is appropriate when “there is a need
    temporarily to suspend the privileges of the certificate or rating
    pending demonstration of qualification or compliance with
    statutory or regulatory requirements.” 
    Id. at 7-1
    to 7-2.
    The Board held that Kornitzky Group’s intentional
    falsification warranted revocation of the company’s certificate
    because it undermined the company’s “care, judgment, and
    responsibility.” Board Decision at *12 (internal quotation
    marks omitted).        But because we vacate the Board’s
    intentional-falsification charge, revocation of the certificate
    can no longer rest on that rationale.
    The Board further found that “revocation is appropriate for
    the remaining violations” for two reasons, neither of which
    withstands scrutiny. 
    Id. The Board
    first concluded that
    indefinite suspension must originate with the FAA as the
    charging agency rather with than the Board. But the Board’s
    own precedent indicates otherwise. See Acting Administrator
    v. Air Trek, Inc., NTSB Order No. EA-5440, 
    2009 WL 1157988
    , at *10 (Apr. 21, 2009) (affirming administrative law
    judge’s reduction of sanction from revocation to indefinite
    suspension). And the Aviation Act grants the Board authority
    to “amend, modify, or reverse” an FAA order as air safety
    requires. 49 U.S.C. § 44709(d)(1).
    20
    The Board additionally observed that the technical data at
    issue is “irrevocably lost” and that imposing an indefinite
    sanction pending compliance would “put both parties in an
    endless, repeating loop.” Board Decision at *12. In that regard
    the Board evidently equated the required technical data with
    the data on the lost Kornitzky computer. But the record
    confirms that the company can acquire technical data in other
    ways. Queitzsch testified that Kornitzky Group could license
    the technical data directly from the OEM, as is typically done.
    Or, as Queitzsch testified, the company could develop the
    technical data itself by “reverse engineering” it (a contention
    confirmed by Galel). Hearing Tr. 310, 555, J.A. 171, 207. And
    in oral argument, the FAA conceded that Kornitzky Group
    could license the technical data from the OEM for the right
    price or reverse engineer the data itself. Oral Arg. Tr. 9. It
    would be up to Kornitzky Group to decide whether to obtain
    the required technical data as a means of ending an indefinite
    suspension of its certificate.
    *   *   *    *   *
    For the foregoing reasons, we grant Kornitzky Group’s
    petition for review in part, vacate the sanction imposed by the
    Board, and remand the matter for further consideration
    consistent with this decision.
    So ordered.
