Direct Answer — Falsifying Maintenance Records
14 CFR §43.12 was the FAA's falsification rule for maintenance records: no person may make a fraudulent or intentionally false entry in a Part 43 record, reproduce a record for a fraudulent purpose, or alter one for a fraudulent purpose — and doing so is a basis to suspend or revoke the offender's certificate. Two things to know in 2026. First, the prohibition is about intent to deceive, not honest mistakes. Second, effective November 3, 2025, the FAA consolidated all of its falsification rules across Title 14 into 14 CFR Part 3, Subpart D (final rule at 90 FR 42517), and §43.12 is now reserved — the same conduct is prohibited under the new §3.403. The stakes are high: the FAA's standard response in falsification cases is generally revocation of all airman certificates, and intentional falsification can also be charged criminally under 18 U.S.C. §1001.

Falsification rules consolidated into 14 CFR Part 3, Subpart D; §43.12 now reserved (90 FR 42517)
Maintenance records are the backbone of airworthiness. They are how you prove an inspection happened, that a part was replaced with the right part, that an airworthiness directive was complied with, and that the aircraft was approved for return to service by someone authorized to do it. Because so much rides on those records being true, the FAA has always treated dishonest recordkeeping in a category of its own — far above an ordinary paperwork miss. A missing date is a discrepancy. A fabricated entry is, to the FAA, a fundamental breach of the trust the whole certification system depends on.
This guide explains what the falsification rule actually prohibits, what changed in the 2025 consolidation, the difference between a wrong entry and a falsified one (it is the whole game), and the records-integrity practices — especially append-only, immutable digital entries — that make a falsification accusation easy to disprove. If you want the upstream rules these records have to satisfy in the first place, start with what a §43.9 maintenance entry must contain and how electronic records and digital signatures work.
What 14 CFR §43.12 Actually Prohibited
Section 43.12 — titled "Maintenance records: Falsification, reproduction, or alteration" — was short, and worth reading in its own words. It had two paragraphs (there was no paragraph (c)):
14 CFR §43.12 — the operative text
(a) No person may make or cause to be made:
- (1)Any fraudulent or intentionally false entry in any record or report that is required to be made, kept, or used to show compliance with any requirement under this part;
- (2)Any reproduction, for fraudulent purpose, of any record or report under this part; or
- (3)Any alteration, for fraudulent purpose, of any record or report under this part.
(b) The commission by any person of an act prohibited under paragraph (a) of this section is a basis for suspending or revoking the applicable airman, operator, or production certificate, Technical Standard Order Authorization, FAA-Parts Manufacturer Approval, or Product and Process Specification issued by the Administrator and held by that person.

Three things the wording makes clear
Intent is built in
Two of the three prohibited acts say "for fraudulent purpose," and the first says "fraudulent or intentionally false." The rule is aimed at dishonesty, not accuracy. An honest error you correct properly is not a falsification — but how you correct it matters (more below).
"Make or cause to be made" reaches more than the signer
The phrase "or cause to be made" means a person who directs, pressures, or arranges for a false entry can be reached even if someone else physically wrote it. A shop owner who tells a mechanic to "just sign it off" is not insulated by not holding the pen.
It is a basis for certificate action
Paragraph (b) ties the conduct directly to the offender's FAA certificate — airman, operator, production, and more. This is the hook the FAA uses to pursue suspension or, far more commonly in falsification cases, revocation.
What Changed in 2025: The Falsification Rules Were Consolidated
Citation update — read this before quoting "§43.12"
In a final rule titled "Falsification, Reproduction, Alteration, Omission, or Incorrect Statements" (90 FR 42517, published September 3, 2025; Docket No. FAA-2024-0021; RIN 2120-AL84), the FAA consolidated the many separate falsification provisions scattered throughout Title 14 — §43.12, §61.59, §65.20, §121.9, §145.12 and others — into a single subpart: 14 CFR Part 3, Subpart D. The rule became effective November 3, 2025. As a result, §43.12 is now reserved: the maintenance-record falsification prohibition still exists, but it now lives in the consolidated Part 3 rule.
The FAA's stated goal was to eliminate inconsistencies among the various falsification rules and their associated sanctions, and to standardize them in one place so the same conduct is treated the same way regardless of which kind of certificate or record is involved. For an operator, the practical takeaways are simple:
| Provision in the new Part 3, Subpart D | What it addresses |
|---|---|
| §3.403 — Falsification, reproduction, alteration | Fraudulent or intentionally false statements, and reproduction or alteration for a fraudulent purpose — the direct successor to the old §43.12(a) prohibition. |
| §3.405 — Incorrect statements / omissions | Incorrect statements or omissions of fact, tailored to the circumstances — recognizing that not every honest error is fraud. |
| Consequences | The rule preserves the certificate-action exposure (denial, suspension, modification, revocation) and provides for civil penalties where applicable. |
| 14 CFR §43.12 | Now reserved. The conduct it described is prohibited under the consolidated rule above. |
Because this is a recent change, always confirm the exact current section number and wording against the regulation (via the Cornell Legal Information Institute or the Federal Register final rule at 90 FR 42517) before relying on a citation in any filing or correspondence. The bottom line for compliance practice does not change: dishonest maintenance records are prohibited and dangerous, whatever the section number.
The best defense against a falsification accusation is records you can prove are honest.
FileFlo keeps your maintenance and airworthiness records classified, time-stamped, attributed, and immutable — so "prove you didn't alter this" is a question your records answer for you. Check where your aviation records stand in a few minutes.
The Penalties: Two Tracks That Can Run at Once
People search for "the penalty" expecting one number. There isn't one — falsification can produce consequences on two separate tracks, administrative and criminal, and they are not mutually exclusive. We describe the process accurately below and deliberately do not invent case counts, percentages, or dollar totals, because outcomes are fact-specific.
Track 1 — FAA certificate action
- The rule makes falsification a basis to suspend or revoke the certificate held by the offender.
- In falsification cases the FAA's general policy is to seek revocation of all of a mechanic's airman certificates — not a short suspension.
- A revoked airman typically must wait a period (often at least a year) before being eligible to reapply for any certificate.
- The FAA can pursue revocation through its emergency authority where it determines safety requires it.
- Appeals run through the NTSB; the Pilot's Bill of Rights (a federal statute) provides certain procedural protections for airmen in these proceedings.
Track 2 — Federal criminal exposure
- Intentional false statements in records used to show compliance with federal requirements can be charged under 18 U.S.C. §1001 (false statements), a felony statute.
- Other federal statutes can apply depending on the facts (for example, aircraft-parts fraud or obstruction).
- Criminal matters can involve the FBI, DOT-OIG, and U.S. Attorneys — not just the FAA.
- A criminal case and an FAA certificate action can proceed in parallel; one does not replace the other.
- Penalties on this track can include fines and imprisonment, separate from any certificate loss.
There is a reason falsification is treated so much more harshly than an ordinary discrepancy. A late or incomplete entry is a paperwork problem. A false entry undermines the thing the entire airworthiness system runs on — the assumption that a signed record is true. If an inspector cannot trust the records, they cannot trust the aircraft. That is also why the related conduct around an investigation matters: see how the FAA fines ordinary Part 135 paperwork violations for contrast, and the difference between a compliance action and formal enforcement — falsification is the kind of case that is far less likely to be resolved as a non-punitive compliance action.
A Wrong Entry Is Not a Falsified One — How You Handle It Decides Which
This is the most important practical point in the whole topic. The rule targets intent to deceive, not inaccuracy. Mechanics are human; entries get transposed, tach times get misread, a wrong part number gets written down. None of that is falsification. But the way you fix it is itself evidence — and a clumsy fix can make an innocent mistake look like a cover-up.
Good faith looks like this
- You make a new, dated correcting entry that explains the change.
- The original (incorrect) entry stays visible — you do not erase it.
- Electronic records keep the prior version with a time-stamp and author.
- The correction happens promptly once the error is found.
This is what creates a falsification problem
- Erasing, whiting-out, or overwriting the original entry.
- Backdating a correction so it appears compliance was timely.
- Replacing a page or re-printing a "clean" record without a trail.
- Signing off an inspection or work that was never actually done.
The mechanics of doing a correction the right way are worth getting exactly right. We cover them in how to correct a maintenance logbook entry, and the related question of rebuilding records you no longer have in how to reconstruct lost aircraft logbooks — where the cardinal rule is that a reconstruction must be transparently labeled as such, never dressed up to look like an original.
Why Append-Only, Immutable Records Make Falsification Optics Disprovable
Falsification is, in the end, an argument about whether a record was honest and unaltered. That argument is easiest to win when the record itself cannot be quietly changed — and proves it. This is the core advantage of append-only, immutable digital recordkeeping: instead of editing an entry in place, every change is captured as a new, time-stamped, attributed version, and the prior state is preserved.
Entries are write-once
Once an entry is committed it is locked. A correction is added as a new entry that references the old one — there is no mechanism to silently overwrite history. That removes both the temptation and the means to falsify.
Every version is time-stamped and attributed
The system records when each entry was made and by which identified person. A backdate is visible because the real timestamp is captured independently of the date a person types into the form.
The audit trail tells the story for you
If anyone ever questions an entry, you can show the full, tamper-evident history rather than asserting it. "Prove you didn't alter this" becomes a report you produce, not a claim you have to be believed on.
It still has to meet the FAA's electronic-records expectations
Immutability is necessary but not sufficient — electronic records must also be legible, retained for the required periods, and carry the §43.9 content and the right signatures. A good system handles both.
For how digital signatures and electronic logbooks satisfy the FAA's requirements in the first place, see electronic aircraft maintenance records and digital signatures. And remember that the same integrity discipline applies to the records the FAA and NTSB demand after an event — the duty to preserve records under NTSB Part 830 means clean-up is never an option, and a records request during an investigation is exactly when immutable history earns its keep.
The Records Most Often at the Center of a Falsification Question
Falsification allegations cluster around the records that prove work and airworthiness. Here is where they tend to surface, the governing rule, and why integrity matters for each.
| Record | Governing rule | Why integrity matters |
|---|---|---|
| Maintenance / return-to-service entry | 14 CFR §43.9 | A false "approved for return to service" can mean an unairworthy aircraft was flown |
| Inspection records (annual, 100-hour, progressive) | 14 CFR §43.11 / §91.409 | Signing off an inspection that was not performed is a classic falsification fact pattern |
| Major repair & alteration (Form 337) | 14 CFR §43.9 / Part 43 App. B | Altering a 337 to hide unapproved data or a failed alteration is reproduction/alteration for fraudulent purpose |
| Airworthiness directive (AD) compliance records | 14 CFR §91.417 | Recording AD compliance that did not happen leaves a latent safety defect uncorrected |
| Maintenance-record retention chain | 14 CFR §91.417 / §135.439 | Missing or "re-created" records invite suspicion; an immutable chain forecloses it |
| Airman / mechanic credentials backing the sign-off | 14 CFR §65 / §3.403 | A sign-off by an unqualified or misrepresented signer is its own falsification exposure |
FileFlo as the Records-Proof Layer — Not Your Enforcement Defense
FileFlo is a compliance document intelligence platform — a proof layer for your records. To be clear about what it does not do: it does not represent you to the FAA or NTSB, respond to an enforcement action or records demand for you, give legal advice, decide whether to file a voluntary disclosure, or guarantee any outcome. Those are your decisions and your counsel’s. What FileFlo does is keep your maintenance and airworthiness records honest by design and easy to produce — which is the single best way to make a falsification accusation a non-starter.
- Captures every entry as append-only, time-stamped, and attributed — so corrections are versioned, never silent overwrites
- Preserves a tamper-evident history you can produce on demand to show a record was not altered
- Holds §43.9 entries, inspection records, Form 337s, and AD-compliance records together with the credentials behind each sign-off
- Classifies 600+ document types and flags gaps in the retention chain before they become "missing record" suspicions
- Surfaces an inspector- or investigator-ready records index, so "produce the records" is a button, not a scramble
- Keeps the documents current and complete — it is the proof layer, not your safety program, your dispatch system, or your lawyer
FileFlo classifies 600+ document types and manages records across Part 91, Part 135, and Part 145 operators. Pricing: Starter $89/mo, Professional $299/mo. 5-day free trial, no credit card required. FileFlo keeps the documents that prove compliance audit-ready — it is not an SMS, a dispatch/flight-operations system, or an enforcement-defense service, and it does not claim SOC 2 certification.

Frequently Asked Questions
What is 14 CFR §43.12 and what does it prohibit?
Section 43.12 was the FAA's long-standing falsification rule for maintenance records. It stated that no person may make or cause to be made (1) any fraudulent or intentionally false entry in any record or report required to show compliance with Part 43, (2) any reproduction, for fraudulent purpose, of any such record or report, or (3) any alteration, for fraudulent purpose, of any such record or report. It also provided that committing any of those acts is a basis for suspending or revoking the certificate held by that person. Important update: effective November 3, 2025, the FAA consolidated all of its falsification rules across Title 14 into one place — 14 CFR Part 3, Subpart D — and §43.12 is now reserved. The conduct it described is still prohibited; it just lives in the new consolidated rule. This is general compliance-document information, not legal advice — see an aviation attorney for any actual matter.
Did §43.12 go away? Where is the falsification rule now?
The substance did not go away — it moved. In a final rule titled "Falsification, Reproduction, Alteration, Omission, or Incorrect Statements" (90 FR 42517, published September 3, 2025; Docket No. FAA-2024-0021; effective November 3, 2025), the FAA consolidated the many separate falsification provisions scattered through Title 14 into a single subpart, 14 CFR Part 3, Subpart D. Within that subpart, §3.403 carries the falsification prohibition — fraudulent or intentionally false statements — and §3.405 addresses incorrect statements or omissions of fact. Section 43.12 itself is now reserved. So if you are reading older guidance that cites "§43.12," the prohibition is real and current, but the citation you want going forward is the Part 3, Subpart D falsification rule. Always verify the exact current section against the regulation before relying on it.
What are the penalties for falsifying aircraft maintenance records?
There are two separate tracks, and they can run at the same time. On the FAA certificate side, falsification is treated as one of the most serious recordkeeping violations: under the rule the act is a basis for suspending or revoking the certificate held by the person — and the FAA's published policy in falsification cases is generally to seek revocation of all of a mechanic's airman certificates, not a short suspension. Revocation can also be pursued through the FAA's emergency authority. On top of that, intentional falsification of records used to show compliance with federal aviation requirements can expose a person to federal criminal liability under 18 U.S.C. §1001 (false statements). The exact outcome of any given case is fact-specific and depends on intent, materiality, and the evidence. We do not quote case counts or dollar figures here because outcomes vary — consult a qualified aviation attorney.
Is falsifying maintenance records a crime?
It can be. Beyond the FAA's administrative certificate action, intentionally making a false statement in a record or report used to show compliance with a federal requirement can be prosecuted as a federal crime under 18 U.S.C. §1001, which is a felony statute. Whether a given matter is handled as an FAA certificate action, a criminal referral, or both depends on the facts, the intent involved, and the agencies that get involved. Because the criminal exposure is real and the stakes are high, this is precisely the kind of situation where you stop talking and call counsel — not a blog. This page is general compliance-document information, not legal advice.
What counts as a fraudulent or intentionally false maintenance entry?
The standard is about intent. The rule reaches a fraudulent or intentionally false entry — meaning an entry the maker knew was false or made to deceive — not an honest mistake, a typo, or a good-faith error you later correct. That distinction matters enormously. Recording an inspection that was never performed, signing off work that was not done, backdating an entry to create the appearance of timely compliance, copying a record for a fraudulent purpose, or altering a logbook to hide a finding are the kinds of conduct the rule targets. The new consolidated rule reflects the same logic: §3.403 addresses fraudulent and intentionally false statements, while §3.405 separately addresses incorrect statements or omissions of fact tailored to the circumstances, rather than treating every honest error as falsification.
What's the difference between a wrong entry and a falsified one?
A wrong entry is inaccurate; a falsified entry is dishonest. An entry can be incorrect because of a transcription error, a misread tach time, or a genuine misunderstanding — and the correct response to a wrong entry is to make a new, dated correcting entry (never to erase, overwrite, or backdate). A falsified entry, by contrast, involves intent to deceive: the maker knew the statement was false or made it for a fraudulent purpose. The way you handle an error is itself evidence. A timely, transparent correcting entry shows good faith; a quiet erasure or a backdate can make an honest mistake look like a cover-up. That is why how you correct a logbook entry — see our guide on correcting a maintenance logbook entry — is a compliance question, not just a tidiness one.
How do digital, append-only maintenance records help with falsification concerns?
Falsification is, at its core, a dispute about whether a record was honest and unaltered. Append-only, immutable digital records make that dispute far easier to win cleanly. When every entry is time-stamped, attributed to an identified person, and locked so that later changes are added as new versioned entries rather than silent overwrites, the record itself tells the story of when each entry was made and by whom. That does two things: it removes the temptation and the means to quietly backdate or rewrite, and it gives you a defensible, tamper-evident history if anyone ever questions an entry. Electronic recordkeeping has to meet the FAA's requirements for legibility, retention, and signatures — but a well-designed immutable system turns "prove you didn't alter this" from a frightening question into a button you press. FileFlo is the document/proof layer; it does not represent you to the FAA or guarantee any outcome.
A mechanic falsified an entry — what should the operator do?
First, this is a legal situation, not just an internal HR one — involve qualified aviation counsel before you act, because how you respond has both safety and legal consequences. As a general matter: do not destroy, erase, or alter anything (that can compound the problem and looks like spoliation); preserve the original records exactly as they are, including the metadata and version history of any electronic records; determine the airworthiness impact, because a falsified inspection or sign-off may mean required work was never actually done and the aircraft's airworthiness is in question; and make any necessary corrective maintenance entries transparently and with proper dates. Voluntary-disclosure programs may be relevant for the operator's own exposure, but whether and how to disclose is a decision to make with counsel. This is general information, not legal advice.
Make a falsification accusation impossible to land: keep records that prove their own honesty.
FileFlo keeps your maintenance and airworthiness records append-only, time-stamped, attributed, and instantly retrievable — so corrections are versioned, history is tamper-evident, and "produce and prove your records" is a button, not a scramble.
