A certificate listed in an official registry proves that the authority recorded an issuance. It does not prove that the exam, inspection or flight behind the record actually happened. Federal prosecutors in California have just put that gap at the center of a criminal case.

On September 10, 2026, a seven-count indictment was unsealed in the U.S. District Court for the Northern District of California. It names two Oakland Police Department helicopter pilots, Brandon Mart and David Mac, and William Miller, described in court records as a then-FAA aviation safety inspector who worked out of Florida. All three pleaded not guilty the same day, so everything that follows is an allegation from the charging document, not a finding.

What prosecutors say happened

According to the indictment as reported by NBC Bay Area and Aero-News Network, the three men conspired between July 2023 and March 2024 to obtain airman certifications the pilots did not earn. The charging document states that "the conspiracy involved the submission of fraudulent documents related to at least four separate check rides, and resulting in Mart receiving three fraudulent certifications, and Mac receiving one fraudulent certificate."

A checkride is the FAA practical test: an oral examination covering regulations, aircraft systems and weather, followed by a flight on which the applicant demonstrates maneuvers such as takeoffs, landings and emergency operations. The reported account includes a detail any records reviewer will recognize: paperwork reportedly showed Mart completing a checkride in California while the FAA inspector named on the test documentation was in Lakeland, Florida, according to prosecutors as reported by AVweb. Prosecutors also allege Mart received a temporary helicopter airman certificate without completing all required maneuvers. In another example drawn from the indictment, ABC7 News reports that investigators allege the helicopter used in a February 2024 check ride for Mac never left the ground, although the records show the test took place.

Mart faces conspiracy, three counts of FAA registration fraud and two counts of obstruction of justice by falsifying records. Mac faces conspiracy and one fraud count. Miller faces conspiracy and four fraud counts. Reported release amounts diverge between outlets, including in terminology: NBC Bay Area reports bail set at $25,000 each, while Aero-News Network and AVweb both report $250,000 bonds. The Oakland Police Department placed both officers on administrative leave. The case has not been tried.

What a registry entry proves, and what it does not

The FAA's public Airmen Inquiry lets anyone search by a pilot's name. The service states that it does not display Social Security numbers, certificate numbers or dates of birth. What it shows is the recorded fact: this person holds this certificate with these ratings, as far as the registry knows.

That distinction matters here. If the allegations are accurate, the FAA genuinely recorded these certificates. A registry lookup during or after the scheme would likely have returned real entries, because the registry reflects what was filed, not what happened on the flight line. The alleged defect sits one level deeper, in the exam event the record claims to describe.

So there are two different questions an employer can ask:

  • Was a certificate recorded? The registry answers that.
  • Did the exam it rests on occur? The registry cannot answer that.

The rule that can reach back to the record

Federal aviation rules separate the document from the statements behind it. Under 14 CFR 3.403, no person may make a fraudulent or intentionally false statement in any document consisting of or related to an application, certificate, rating or record covered by the rule, or in any document used to show compliance with any requirement it covers.

The consequence provision is 14 CFR 3.405: an incorrect statement or omission of fact that was material to the issuance of a certificate may serve as a basis for suspending, revoking or withdrawing it. In plain terms, a certificate that genuinely exists in the registry can still be undone if the filing that produced it was false. Being recorded and being well-founded are different properties, and the regulation attaches consequences to the second.

What an employer can actually check

The FAA's own verification guidance offers two routes. The online Airmen Inquiry gives a fast public lookup. For a written answer, the Airmen Certification Branch accepts written requests that state the requester's business name, physical and email addresses, along with the airman's full name, date of birth and certificate number. The same page points to a separate channel for accident, incident and enforcement information.

Those routes settle the record. For the event, the evidence lives elsewhere: the checkride scheduling record, the examiner's identity and location on the date in question, the applicant's logbook, and the aircraft's records. In the Oakland indictment, the reported tell was geographic: prosecutors say a digital timestamp placed the inspector in Lakeland, Florida, on the date his paperwork documented a California checkride. That is the kind of inconsistency a document-only review will not catch, because on paper the certificate would still look authentic.

In a fictional example, a charter operator is vetting a helicopter pilot for utility work. The pilot's certificate copy is genuine and the Airmen Inquiry entry matches. The reviewer still asks for the checkride date and examiner, then requests the FAA's written verification for the file. If the operator learns the certificate is under legal challenge, the reviewer's job is to record what is unresolved and hold the assignment decision, not to declare the pilot unqualified on the strength of a news report.

What a document fingerprint settles, and what it cannot

A secure hash is a value calculated from a file's exact contents. Recording that fingerprint at issuance lets a later reviewer prove the file was not altered afterward. That control is real and useful, and this is the boundary around it: the fingerprint binds the document, not the event. It cannot establish that a checkride took place, that the named examiner was present, or that the recorded maneuvers were performed.

The control that fits this case is earlier in the chain. Evidence anchored at the time of the exam, such as a scheduling record, an examiner attestation or location data, is what could later contradict a certificate whose paperwork looks perfect. A certificate anchored after a faked exam would verify cleanly and still be wrong.

For a reviewer, the working rule is modest: confirm the record, then decide how much of the event evidence the role requires, and write down what remains unchecked. A pending indictment changes how much scrutiny is prudent; it does not answer the underlying question by itself.

Our earlier guides cover adjacent parts of this work: checking a pilot's license privileges for the role, verifying who actually signed a maintenance entry and confirming a certificate's current status. AeroCert's verification overview describes the document-integrity half of the problem.
