Automated FAA Airworthiness Directive tracking for the parts and aircraft you're responsible for
Daily alerts when a new or amended Airworthiness Directive touches your part numbers, aircraft models, or ATA chapters — pulled straight from the Federal Register, with every item linked back to the original record. Whether you're tracking by part number or by tail number.
Why Airworthiness Directives are the highest-stakes source to monitor
An Airworthiness Directive (AD) is the FAA's mandatory corrective action — unlike a Service Bulletin or an SAIB, compliance isn't optional. If a new AD affects a part you manufacture under a PMA, a system you service at a Part 145 station, or an aircraft you own, lease out, or operate at a flight school, you need to know — a customer will ask, an inspector will check, or the deadline will simply arrive whether you were watching or not.
The problem isn't that ADs are hard to find — the Federal Register publishes every one of them, in full, for free. The problem is volume and relevance: hundreds of ADs are published every year, covering everything from turbine engines to seat belts, across every manufacturer and aircraft type. Reading all of them to find the handful that actually touch your parts or your specific aircraft isn't a realistic use of anyone's time, and a generic manufacturer/model subscription still leaves you skimming directives that don't apply to you.
How this actually works
No AI, no black box — a straightforward rule-based match against data you can verify yourself.
You tell us what to watch
Part numbers, keywords, aircraft models, and ATA chapters — whatever's specific to what you build or service.
We poll the Federal Register daily
Every weekday, checked against the FAA's own REST API — the same source of record the AD itself links back to.
Aircraft/model data fills the gap
An AD's own metadata rarely names a part number in a structured field, so we cross-reference FAA's DRS system for real Make/Model data, closing a gap that would otherwise make aircraft-level matching unreliable.
You get a tiered, sourced email
Exact part/keyword matches, aircraft+ATA-chapter matches, and aircraft-only matches are shown separately, every one linking straight to the real Federal Register record.
What "tiered" actually means for ADs
Structured AD metadata (title, date, docket number) is reliable, but a specific part number is usually only in the linked PDF's body text — not something an API field reliably exposes. That means Tier 1 (exact keyword or part-number match) is real but less common for this source than for something like FAA Service Difficulty Reports. Tier 2 and Tier 3 — matched on aircraft model and ATA chapter, or aircraft model alone — carry real signal too, and if you're watching by aircraft rather than by part number (a flight school, lessor, or individual owner, for example), these are often your main event, not a fallback: a new AD against your aircraft type is worth knowing about the moment it's published, before anyone's confirmed it names a specific part.
Your report says this explicitly, per source — so a sparse Tier 1 section under Airworthiness Directives reads as expected for this kind of data, not as a sign that matching failed.
