How it works

Public data, no scraping fragility, honest about its limits.

1 · Live AD feed

We poll the Federal Register public JSON API daily for FAA final rules under 14 CFR Part 39 (that's what an AD legally is). Each AD's full text is parsed for the applicable make/model/series, effective date, and compliance window.

2 · Match to your fleet

You add aircraft by make + model (+ optional serial and current hours TIS). We match each AD's applicability against each tail.

3 · Deadlines + status

For recurring ADs we compute the next-due date or hours from the effective date (or your recorded last-compliance). You record method-of-compliance per AD; the status board and audit export follow.

Honest limits

Make/model/series matching is reliable. Serial-exact applicability often depends on a manufacturer Service Bulletin we cannot see in the public AD text, so a model-level match may over-include. We flag match confidence and tell you to verify with your A&P/IA. This is a tracking aid, not a maintenance record.

Informational only — not a maintenance record. This tool surfaces public FAA Airworthiness Directives and computes indicative deadlines from public AD text. It does not determine serial-number or installed-appliance applicability (which can depend on manufacturer Service Bulletins). Always verify applicability and method of compliance with your A&P/IA before any maintenance or dispatch decision. Compliance with 14 CFR Part 39 remains the owner/operator's legal responsibility (14 CFR 91.403).
