Unofficial FAA Airworthiness Directive Monitor: Make & Model

FAA Airworthiness Directive Monitor checks the Federal Register for new FAA airworthiness directives (ADs) under 14 CFR part 39 and returns one clean row per document: AD number, final or proposed, manufacturer, product type (airplane, helicopter, engine, propeller...), affected models, publication and effective dates, comment deadline for proposed ADs, superseded ADs, docket number, and links to the Federal Register page, PDF and Regulations.gov docket. With full text on, each row also carries the AD's Applicability paragraph (models, serial numbers, part numbers), unsafe condition, required actions, JASC/ATA subject code and the FAA's estimate of affected U.S. aircraft.

Put your makes, models, engines or part numbers in a watchlist, turn on new-only monitor mode, and schedule it daily or weekly: you get only the ADs you haven't seen yet.

New documents only. This does not list ADs issued before you started watching, and it does not look up ADs by tail number (no aircraft registry lookup). For the full list of ADs that currently apply to an aircraft, use FAA DRS. Proposed ADs (NPRM/SNPRM) are not mandatory until issued as a final rule; every row's documentKind says which it is.

Built for aircraft owners and type clubs, A&P mechanics and IAs, flight schools, Part 135 operators, small MROs and aviation newsletters who want a structured early heads-up (CSV/JSON, email or Slack via Apify integrations) on new and proposed ADs for the types they fly or maintain. It is a heads-up feed, not an AD compliance record: always confirm applicability and compliance in the FAA's Dynamic Regulatory System (DRS) and your maintenance records.

$0.50 per 1,000 AD documents returned. All of part 39 is usually 40-80 documents a month, so a daily monitor on a short watchlist typically returns a few rows a week and costs cents a month. You need an Apify account (the free plan works). No FAA or Federal Register account or API key is needed.

This is an unofficial tool. It is not affiliated with, endorsed by, or reviewed by the FAA or the Office of the Federal Register. Not legal, airworthiness or maintenance advice (see Limitations).

How to use

1. Add one line per thing you care about to watchlist, e.g. Robinson R44, Piper PA-28, Lycoming O-360, Pratt & Whitney PT6A, Hartzell propellers, or a part number. Leave it empty to get every AD.
2. Keep documentTypes = final + proposed (proposed ADs give you the comment window and an early look at what is coming), or pick one.
3. For a monitor: turn on onlyNew, set a monitorKey, run once (the baseline: everything in the window), then Schedules > Create to run it daily or weekly. Add an email, Slack, Google Sheets or webhook integration to receive the new rows.
4. Open federalRegisterUrl or pdfUrl to read the AD itself, and confirm in FAA DRS (drs.faa.gov) before acting.

How watchlist matching works

• Every word on a line must appear in the AD's title, summary or (with full text on) its Applicability paragraph. Case-insensitive, whole words.
• Model numbers also match letter suffixes: 172 matches 172S and 172RG but not 1720; O-360 matches O-360-A4M but not IO-360 (add IO-360 as its own line if you want both).
• Use the name the FAA uses for the type-certificate holder. Recent Cessna ADs are titled Textron Aviation Inc., usually with (Type Certificate Previously Held by Cessna Aircraft Company), and Beechcraft models such as the B300 also appear under Textron Aviation. If unsure, match the model alone (182 airplanes or R44).
• Serial and part numbers usually live in the Applicability paragraph, so keep includeDetails on if your watchlist uses them; with it off, only the title and summary are matched.
• Fleet estimates (usFleetAffected) appear only where the FAA states one.
• matchedWatchlist shows which lines matched. No rows means no match in this pull only - not that no AD applies to your aircraft.

Output

One row per Federal Register document. Example (trimmed, real data):

{
  "documentKind": "final-ad",
  "adNumber": "2026-21-05",
  "manufacturer": "MD Helicopters, LLC",
  "productType": "helicopter",
  "models": "Model 369D, 369E, 369F, 369FF, 369H, and 500N",
  "publicationDate": "2026-10-23",
  "effectiveDate": "2026-11-27",
  "docketNumber": "FAA-2026-4666",
  "applicability": "This AD applies to MD Helicopters, LLC (MDHI) Model 369D, 369E, 369F, 369FF, 369H, and 500N helicopters, certificated in any category, with an installed main transmission drive shaft coupling (coupling) part number 369H5660 with serial numbers 8564-0001 through 8564-0308.",
  "subjectCode": "6310",
  "requiredActions": "Within 50 hours time-in-service (TIS) or 6 months after the effective date of this AD, whichever occurs first, ... visually inspect each coupling for cracks ...",
  "usFleetAffected": 568,
  "federalRegisterUrl": "https://www.federalregister.gov/documents/2026/10/23/2026-21664/airworthiness-directives-md-helicopters-llc-helicopters"
}

documentKind is one of final-ad, final-ad-immediately-adopted (final rule with request for comments), correction, proposed-ad (NPRM), supplemental-proposed-ad (SNPRM), proposal-withdrawn, comment-period-change, other. Proposed ADs have no AD number yet; the final AD later appears as a new document with the same docketNumber.

Input

Field	Default	Notes
watchlist	empty (all ADs)	One make/model/engine/part per line; see matching rules above
documentTypes	final + proposed	final includes corrections and immediately adopted rules
productTypes	all	From the last word of the AD title (Airplanes, Helicopters, Engines, Propellers, Gliders, Balloons...)
includeCorrections	true
includeDetails	true	One extra request per document to read its full text (applicability, required actions...)
daysBack / dateFrom	30 days	Publication-date window, counted back from today (UTC)
onlyNew / monitorKey	off	New-only mode; repeats are not output or charged
maxItems	500	Newest first; capping a monitor's first run leaves its baseline incomplete

With no watchlist you get every AD document in the window. As a dated example, all of part 39 was 55 Federal Register documents in the 30 days to Oct 26, 2026, counting final ADs, proposals, corrections and withdrawals together (not 55 new mandatory ADs).

Limitations

• Federal Register only. Covers ADs as published in the Federal Register (final, proposed, corrections). Emergency ADs go to known owners/operators first and reach the Federal Register after (normally within 30 days); if you are not a known owner (for example a recent buyer or a non-U.S. owner) you may not get direct notice, and this feed will only show the AD once it is published. Special Airworthiness Information Bulletins (SAIBs), service bulletins and foreign (EASA, TCCA) ADs are not included.
• Not a compliance record. It does not know your aircraft's serial numbers, configuration or maintenance history, and an AD's applicability often depends on serial or part numbers. Treat a match as "read this AD", and a non-match as "nothing matched in this pull", never as "no AD applies". Confirm in FAA DRS.
• Text extraction is best-effort. Models, applicability, required actions and fleet estimate are parsed from Federal Register text and can be truncated or missed when the document layout differs; the linked document is authoritative. requiredActions is capped at 2,000 characters and applicability at 2,500.
• Timing. Federal Register documents are published on business days; dates are publication dates (UTC window). This is a scheduled check, not a real-time alert.
• Data source and use. Data comes from the Federal Register API (federalregister.gov/developers), which needs no key; requests carry a declared User-Agent with contact email and are paced (no more than 4 per second). Federal Register content is a U.S. government work. Unofficial: not affiliated with, endorsed by or reviewed by the FAA, the U.S. Department of Transportation or the Office of the Federal Register.

FAQ

Can I backfill history? Yes: set dateFrom (up to 10 years back) and raise maxItems; turn includeDetails off for a fast metadata-only pull.

Can I track only proposed ADs to comment on them? Set documentTypes to proposed; commentsCloseOn and regulationsGovUrl tell you when and where to comment.
