Hardwick v. FAA — Pilot-in-Command Must Independently Verify Registration/Airworthiness; “Administrative” Unairworthiness and Narrow Reasonable-Reliance Defense Support FAA Suspension

1. Introduction

In Hardwick v. FAA (5th Cir. Mar. 23, 2026), professional pilot Glen A. Hardwick petitioned for review of a National Transportation Safety Board (NTSB) order affirming the Federal Aviation Administration’s (FAA) 150-day suspension of his pilot certificate. The enforcement action arose from two flights Hardwick operated in a Cessna Citation 550 whose externally displayed tail number did not match its current registration paperwork, and whose airworthiness certificate did not reflect the aircraft’s current registration.

The core disputes were: (1) whether Hardwick could avoid liability by claiming reasonable reliance on the aircraft owner’s statements (and allegedly on FAA database information) suggesting the tail number had “reverted”; (2) whether the sanction was excessive because the violations were “administrative” rather than safety-related; and (3) whether unequal treatment compared to another pilot (Scott Breeze) rendered the decision arbitrary.

2. Summary of the Opinion

The Fifth Circuit denied the petition and upheld the 150-day suspension. The court emphasized:

  • Deferential review of agency decisions and sanctions; the court would intervene only if the sanction was “unwarranted in law” or “without justification in fact.”
  • Hardwick waived any “substantial evidence” challenge at oral argument and in any event forfeited it by inadequate briefing, leaving only an arbitrary-and-capricious challenge.
  • The NTSB reasonably rejected Hardwick’s reasonable reliance defense because he was the pilot-in-command, had an independent obligation and ability to verify the aircraft’s registration/airworthiness status, and ignored multiple “red flags,” including a written Condition Notice.
  • “Administrative” deficiencies can still render an aircraft unairworthy for regulatory purposes; the agency was not required to mitigate the sanction simply because the mismatch was paperwork-driven.
  • Alleged disparate treatment compared to Breeze did not establish arbitrariness because the FAA later concluded the Breeze incident involved an initial agency mistake and materially different circumstances (Breeze flew with the correct external tail number).

3. Analysis

A. Precedents Cited

1) Agency review structure and roles

  • Pham v. NTSB, 33 F.4th 576 (D.C. Cir. 2022): Cited for the division of authority—FAA as regulator/enforcer and the NTSB as adjudicator—and also for the standard of deference when reviewing NTSB sanction decisions. The Fifth Circuit used Pham to situate this case within the familiar FAA/NTSB enforcement framework and to reinforce that sanction review is highly deferential.
  • Garvey v. NTSB, 190 F.3d 571 (D.C. Cir. 1999): Quoted via Pham for the same structural point regarding FAA enforcement and NTSB adjudication.

2) Standard of review (arbitrary-and-capricious; substantial evidence) and deference to sanctions

  • Miranda v. NTSB, 866 F.2d 805 (5th Cir. 1989): The central Fifth Circuit authority used repeatedly. It supplies: (i) the Administrative Procedure Act framing for reviewing agency action (“arbitrary, capricious, an abuse of discretion...or unsupported by substantial evidence”); and (ii) the rule that once FAA establishes a prima facie case, the burden shifts to the pilot to prove an affirmative defense.
  • Bowman Transp., Inc. v. Ark.-Best Freight Sys., Inc., 419 U.S. 281 (1974): Quoted (through Miranda) for the canonical arbitrary-and-capricious formulation: the agency must consider relevant factors and avoid clear errors of judgment; reviewing courts do not substitute their judgment.
  • Am. Power & Light Co. v. SEC, 329 U.S. 90 (1946), and Phelps Dodge Corp. v. NLRB, 313 U.S. 177 (1941): These establish the especially deferential approach to agency remedial choices—“the relation of remedy to policy is peculiarly a matter for administrative competence”—and that courts intervene only if the remedy is “unwarranted in law” or “without justification in fact.” The Fifth Circuit imported this deference directly into FAA/NTSB sanction review, making clear that disagreement with the severity of a suspension is not enough.

3) Waiver/forfeiture for inadequate briefing

  • Willis v. Cleco Corp., 749 F.3d 314 (5th Cir. 2014), quoting United States v. Scroggins, 599 F.3d 433 (5th Cir. 2010): Cited for the proposition that litigants must “press” claims; mere mention or allusion is insufficient.
  • Rollins v. Home Depot USA, 8 F.4th 393 (5th Cir. 2021): Cited for forfeiture when briefing is inadequate.

4) Claims of adjudicator bias based only on adverse rulings

  • Dondero v. Jernigan, No. 24-10287, 2025 WL 1122466 (5th Cir. Apr. 16, 2025) (unpublished), cert. denied, No. 25-355, 2026 WL 79972 (U.S. Jan. 12, 2026), reh’g denied, No. 25-355, 2026 WL 642816 (U.S. Mar. 9, 2026): Used to reject the notion that losing evidentiary or procedural rulings, without more, prove bias.
  • Crummey v. Comm’r of Internal Revenue, 684 F. App’x 416 (5th Cir. 2017) (unpublished): Cited for the same general principle in the disqualification context.

5) The NTSB’s “reasonable reliance” doctrine

  • Administrator v. Haddock, No. EA-5596, 2011 WL 3958427 (N.T.S.B. Aug. 29, 2011): This is the opinion’s key doctrinal reference for reasonable reliance. It frames reliance as narrow and fact-specific, generally limited to specialized technical tasks allocated to others where the pilot has no independent duty/ability to verify and no reason to question performance. The Fifth Circuit treated Haddock as defining the contours of the defense and then held Hardwick’s conduct fell outside those contours.

6) Administrative versus physical airworthiness

  • Legal Opinion on Whether Any Regulation Proscribes an Approval for Return to Service of a U.S.-Registered Aircraft Following an Inspection Required by 14 C.F.R. part 91, 125, or 135 if the Aircraft Registration Certificate is Not Current?, 2012 WL 2368333 (D.O.T. June 18, 2012): Cited to support the proposition that airworthiness status can be lost for administrative/paperwork reasons, not only mechanical condition. The court used this to reject Hardwick’s mitigation argument that “no safety harm” should reduce the sanction.

B. Legal Reasoning

1) The court narrowed the appeal to arbitrariness, not evidentiary sufficiency

A consequential procedural move in the opinion is its treatment of review scope. Hardwick’s counsel conceded “substantial evidence” supported the NTSB’s decision, and the court also held Hardwick failed to brief a substantial-evidence challenge adequately. With evidentiary sufficiency off the table, Hardwick had to show the NTSB’s decision and the sanction were irrational, legally wrong, or disconnected from the factual record—an uphill battle under Bowman Transp., Inc. v. Ark.-Best Freight Sys., Inc. and Am. Power & Light Co. v. SEC.

2) Reasonable reliance is “narrow,” and pilot-in-command responsibility dominated the analysis

Hardwick’s principal theory was that he reasonably relied on the owner’s explanation that denial of a new airworthiness certificate caused the tail number to “revert” and (he claimed) on an FAA database entry he recalled seeing. The Fifth Circuit rejected this for two interlocking reasons:

  1. Role allocation: Under Administrator v. Haddock, reliance is viable only where a task is assigned to another, the pilot has no independent obligation or ability to verify, and the pilot has no reason to question the other’s performance. The court stressed that Hardwick was the pilot-in-command and sole crew member and therefore “ultimately responsible” for ensuring the aircraft’s airworthy condition prior to and during operation. On these facts, verifying correct registration/airworthiness documentation was not a specialized task reserved for others; it was part of the pilot’s core compliance duties.
  2. Red flags defeated reasonableness: Even if reliance were theoretically available, the court found Hardwick faced repeated warning signs: “paperwork issues,” taped alteration of the tail number, multiple onboard documents he did not review, and a written Condition Notice plus a verbal warning from FAA inspectors in Wichita. Continuing the return flight without reading the notice and without a Special Flight Permit reinforced the conclusion that reliance was not reasonable under the NTSB standard.

3) The “tail number reversion” theory did not carry legal weight

The court also treated Hardwick’s “reversion” narrative as both (a) unsupported by the record and (b) largely immaterial to the reliance inquiry. The NTSB relied on the “Assignment of Special Registration,” credible inspector testimony about current registration documents for N550MK, contemporaneous reports reflecting the database showed N550MK, and the owner’s later request to change back to N550ME—suggesting no automatic reversion had occurred.

But more fundamentally, the court held that even if Hardwick believed in reversion, he still had the obligation to verify the aircraft’s current registration and airworthiness status at the time of operation. In other words, the case frames “reversion” as a distraction from the compliance duty of the pilot-in-command.

4) “Administrative” unairworthiness remains sanctionable; mitigation is not required

Hardwick argued the sanction was excessive because the aircraft was only unairworthy due to paperwork mismatch, not physical condition. The court drew a firm distinction: the FAA did not need to prove Hardwick flew an unsafe aircraft, only that he flew an aircraft deemed unairworthy under the regulatory scheme (including certificate/registration mismatches). Relying on the DOT legal opinion and the regulatory structure, the Fifth Circuit confirmed that “administrative” deficiencies can support enforcement and that the NTSB’s decision not to mitigate was not arbitrary.

5) Disparate treatment claims failed because the comparator was not truly comparable

Hardwick’s proportionality argument based on pilot Scott Breeze turned on alleged inconsistency: Breeze was told he displayed the wrong tail number (N550MK) but apparently received no sanction, while Hardwick was suspended. The court accepted the agency’s explanation: the Breeze incident was later deemed an FAA mistake after further investigation, and Breeze flew while the plane displayed N550MK (the correct tail number for the new registration), whereas Hardwick flew displaying N550ME (the incorrect number after the registration change). That difference broke the analogy and defeated the arbitrariness claim.

C. Impact

  • Tightened practical boundaries on “reasonable reliance” for pilots: The opinion signals that reliance on owners, informal explanations, or perceived database entries will rarely excuse noncompliance when the pilot-in-command can verify aircraft documents and physical markings, especially after receiving direct FAA warnings.
  • Reinforcement of “administrative airworthiness” enforcement: The court’s rejection of “paperwork only” mitigation supports robust enforcement of documentation/marking rules (tail number display, proper certificates) as independently important to the aviation regulatory system (traceability, accountability, and standardized compliance checks).
  • Procedural lesson for petitioners: By holding that Hardwick waived/forfeited “substantial evidence” arguments, the opinion underscores that petitioners must brief evidentiary sufficiency carefully; otherwise, review collapses into highly deferential arbitrariness scrutiny.
  • Comparator-based arbitrariness arguments face a high bar: Even an apparent disparity will not establish arbitrariness if the agency can explain the comparator as factually distinguishable or as the product of a corrected mistake.

4. Complex Concepts Simplified

  • Tail number: The aircraft’s external registration identifier (like a license plate). Regulations require the aircraft to display the correct registered tail number.
  • Registration vs. airworthiness certificate: Registration identifies ownership/registration status; an airworthiness certificate reflects the aircraft’s authorization to operate and must match the aircraft’s identity (including tail number as reflected in the certificate/registration scheme).
  • “Airworthy” vs. “safe”: “Safe” is a practical concept about physical condition; “airworthy” is also a legal/regulatory status that can be lost due to paperwork or certification defects, even if the aircraft is mechanically sound.
  • Condition Notice: A written notice from inspectors identifying regulatory issues and warning that operation before correction may violate regulations; here, it also flagged the need for a Special Flight Permit if the aircraft were to be moved without full compliance.
  • Special Flight Permit: Authorization (often for ferrying) to operate an aircraft that may not meet normal airworthiness requirements, under specified conditions.
  • Arbitrary-and-capricious review: A narrow judicial review standard asking whether the agency considered relevant factors and made a rational decision—not whether the court would have decided differently.
  • Substantial evidence: A separate review concept asking whether enough evidence supports the agency’s factual findings. Hardwick did not preserve this challenge.
  • Waiver vs. forfeiture: Waiver is intentionally giving up an argument (here, conceding substantial evidence). Forfeiture is losing an argument by failing to present it properly (here, inadequate briefing).
  • Affirmative defense burden: Once FAA establishes a violation, the pilot must prove any excuse/defense (e.g., reasonable reliance).

5. Conclusion

Hardwick v. FAA solidifies a practical rule for FAA enforcement review in the Fifth Circuit: a pilot-in-command cannot evade responsibility for tail-number and documentation mismatches by invoking a broad “reasonable reliance” claim—especially when multiple red flags and direct inspector warnings are present. The court also affirmed that “administrative” paperwork defects can render an aircraft unairworthy as a matter of law and justify meaningful certificate suspension, and it reiterated the judiciary’s strong deference to the FAA/NTSB’s sanction choices. In the broader regulatory context, the decision reinforces documentation accuracy as a central compliance obligation, not a technicality.
