Airworthiness Directive Feed: EASA, FAA and Transport Canada fleet watch

Get new and revised airworthiness directives (ADs) for the aircraft, engines and helicopters you track, from two official sources in one machine-readable feed:

• the EASA Safety Publications Tool: EASA ADs, emergency ADs and proposed ADs (PAD), plus the FAA, Transport Canada, ANAC, UK CAA and other foreign directives that EASA republishes;
• the Federal Register: FAA final ADs, proposed rules (NPRM/SNPRM) with comment deadlines, and corrections.

The feed is built for CAMOs, MROs, operators and aircraft owners, aircraft traders and lessors, and developers of maintenance-tracking software who want ADs in a spreadsheet, database or agent workflow instead of separate e-mail alerts.

What this Actor adds

• One watch list across authorities. List manufacturers and models once (for example Airbus / A320, 737-8, H160). A model is matched as a whole designation: 737-8 matches 737-8 (MAX) but not 737-800 or 737-8200. 737 matches the whole family.
• EASA ↔ FAA links. For matched FAA documents the Actor reads the official FAA text on govinfo.gov and lists the EASA, Transport Canada or ANAC directive it is based on (relatedDirectives), plus the ADs it supersedes (supersedes). Example from our tests: FAA AD 2026-21-02 references EASA AD 2026-0152. referencesChecked tells you whether the text was actually read.
• One record per directive. An FAA AD republished in the EASA tool and published in the Federal Register is merged into one record, with seenIn showing both sources and the FAA docket, amendment and abstract added.
• Proposals and emergencies. EASA PADs and FAA NPRMs come with their comment deadline (commentsCloseOn). Emergency ADs have status: emergency.
• Revisions. EASA revisions (R1, R2) list the revision they replace in supersedes.
• Changes mode. With a named state store, changes mode returns only directives that are new, or whose fields changed, since the previous run with the same watch list. changedFields names what changed. Directives already delivered are not charged again.

Input

Field	Description
watch	Up to 100 entries: manufacturer and/or model, optional label. Empty = all directives in the window
sources	easa, federal-register (default both)
authorities	Optional filter: EASA, FAA, TCCA, ANAC, UK CAA, CAAI, CASA, JCAB, CAAC, CAA NZ, OTHER
includeProposed	Include PAD and NPRM/SNPRM (default true)
lookbackDays	Window of 1–365 days (default 30)
linkReferences, maxTextFetches	Read official FAA texts for links (default true, up to 100 texts per run)
mode, stateStoreId	snapshot, or changes with a named store
maxRecords	Upper limit on delivered directives (default 1000)

Example:

{
  "watch": [
    { "label": "A320 family", "manufacturer": "Airbus", "model": "A320" },
    { "label": "Boeing 737 MAX 8", "model": "737-8" },
    { "label": "H160", "model": "H160" }
  ],
  "lookbackDays": 30,
  "mode": "changes",
  "stateStoreId": "my-fleet-ads"
}

Output

One dataset item per directive:

• directiveKey (for example EASA:2026-0193, FAA:2026-20-11, FAA-NPRM:2026-20885), authority, adNumber, class, status (final, emergency, proposed, correction), revision
• issueDate, effectiveDate, commentsCloseOn
• subject, manufacturers, models, ataChapter, abstract
• FAA details: docket, amendment, mcaiProjectId, frDocumentNumber
• relatedDirectives, referencesChecked, supersedes
• documentUrls (EASA PDFs, official FAA text), sourceUrl, seenIn, matchedWatch
• change (new, updated, unchanged, not-tracked), changedFields, observedAt, contentHash

The SUMMARY record lists the window, item counts per source, matches per authority and any FAA texts that could not be read.

Pricing

• $0.01 per delivered directive, plus $0.005 per run start.
• In changes mode, directives already delivered are not delivered or charged again.
• A run fails without delivering anything if a selected source cannot be read, so you never receive a partial feed that looks complete.

Data sources and terms

• EASA Safety Publications Tool, ad.easa.europa.eu. EASA states that reproduction is authorised provided the source is acknowledged. Source: EASA.
• Federal Register API and govinfo.gov, U.S. Government works.

This Actor reports what the authorities published. It does not decide whether a directive applies to a specific serial number, configuration or modification status, and it does not record compliance. Always use the official directive text and your approved maintenance processes. A directive missing from the feed does not mean that no directive applies. Emergency ADs that the FAA sends directly to owners may appear in the Federal Register only later.

Limits

• Matching uses the manufacturer and model text published by each source. FAA records are matched on the title and abstract, so models listed only in the full text are not matched.
• Links come from the FAA text only. EASA PDFs are not parsed.
• The EASA export is capped at 4000 items per request. Very long windows without a watch list may hit that cap, and the run then fails with an explanation.
