Airworthiness Directives and Service Bulletins, by model.

Search by aircraft or engine make and model, sourced from the Federal Register and manufacturer records.

Every record carries its source. Airworthiness Directives link directly to their Federal Register document and are checked against the live government record; Service Bulletins link to the manufacturer source. Airworthiness Directives are legally enforceable FAA rules (14 CFR 39.3). Service Bulletins are manufacturer documents with no independent FAA force; where an Airworthiness Directive incorporates one, the directive controls what is required, and where a bulletin revises an FAA-approved Airworthiness Limitations section, the limitations applicable to that aircraft govern under 14 CFR 91.403(c), subject to approved alternatives, and a later revision is not automatically retroactive. Each record points to the directive or the limitations section where one applies.

How this works

Why owners can trust this page

01

Straight from the official record

Every Airworthiness Directive here restates a specific Federal Register document, linked directly beneath it.

02

Checked against the live record

Each Airworthiness Directive is re-checked against the live Federal Register document, and shows the date of its last successful check — or says plainly when one hasn't succeeded yet.

03

We never guess

We do not determine airworthiness and we do not sell parts. Where our indexed data ends, we say so plainly.

In development: N-number lookup and saved-aircraft watchlists.
