How to Find and Track Airworthiness Directives for Your Aircraft: A Step-by-Step Guide

Meta description: Learn how to search FAA and EASA airworthiness directives for your aircraft by make, model, and serial number, plus track AD compliance effectively.

You’re responsible for knowing which airworthiness directives apply to your aircraft. Miss one, and you’re flying an unairworthy aircraft—regardless of whether the oversight was innocent. The problem: ADs are scattered across multiple databases, issued by different authorities, and the applicability criteria can be buried in technical language. This guide walks you through the exact process for finding every AD that affects your aircraft and keeping track of compliance status over time.

What Airworthiness Directives Are and Why They’re Mandatory

Airworthiness directives are legally binding requirements issued when a safety defect is identified in a type-certificated product—aircraft, engine, propeller, or appliance. They’re not recommendations. Under FAA regulations (14 CFR 39.7), no person may operate a product to which an AD applies unless the requirements of that AD have been met. EASA takes the same position under Part-M, M.A.303: the aircraft is not airworthy if applicable ADs aren’t complied with.

ADs typically require one of three actions: a one-time inspection, a repetitive inspection at specified intervals, or a modification that terminates the recurring requirement. Some ADs give you options—you might be able to install a superseding modification instead of continuing repetitive inspections.

The critical point: AD applicability is determined by the type certificate holder’s design, but the compliance burden falls entirely on the owner/operator. Your maintenance organization will implement the AD, but you’re the one who needs to ensure it gets done. If you’re operating under owner-approved maintenance programs, this responsibility is even more direct.

ADs aren’t retroactive in terms of timing—you don’t suddenly owe back-compliance when a new AD drops—but they apply immediately to aircraft that meet the applicability criteria. An AD issued today that applies to your aircraft serial number becomes a compliance requirement today, even if the underlying condition has existed since manufacture.

How to Search the FAA Airworthiness Directive Database

The FAA maintains its AD database through the Regulatory and Guidance Library at drs.faa.gov. Here’s the exact process for finding airworthiness directives aircraft owners need to track:

Step 1: Access the correct search interface. Navigate to rgl.faa.gov, select “Airworthiness Directives” from the document types. You’ll see search options for aircraft, engine, propeller, and appliance ADs.

Step 2: Search by type certificate data sheet (TCDS) criteria. For aircraft ADs, enter your make and model exactly as it appears on your TCDS—not the marketing name. A Cessna 172S is listed under “Cessna” (make) and “172S” (model), not “Skyhawk.” The database is literal.

Step 3: Filter by applicability. Results will show all ADs ever issued for that type certificate. Many won’t apply to your specific aircraft because of serial number ranges, modification status, or component part numbers. Read the Applicability section of each AD carefully. An AD for “Model 172S aircraft, serial numbers 172S8001 through 172S9500” doesn’t apply to serial number 172S10200.

Step 4: Check for superseding ADs. ADs can be amended or superseded. If AD 2019-15-06 was superseded by AD 2022-03-11, you comply with the newer one—but you need to verify whether previous compliance actions count or whether additional steps are required.

Step 5: Don’t forget engine and propeller ADs. Your FAA airworthiness directive search must include the powerplant. Search separately for your engine type (e.g., Lycoming IO-360-L2A) and propeller (e.g., McCauley 1A170/GM8235). These ADs are filed under the engine or propeller manufacturer, not your aircraft manufacturer.

Step 6: Document your search. Record the date you searched, the search parameters, and the results. If an AD doesn’t apply because of serial number exclusion, note that with the specific exclusion language. This documentation becomes part of your airworthiness argument.

How to Search the EASA AD Portal for European Compliance

EASA maintains a dedicated AD portal at ad.easa.europa.eu. The process differs from the FAA system:

Step 1: Understand the dual-AD environment. EASA may issue its own ADs for products type-certificated in Europe, but it also mandates compliance with ADs from the State of Design. For a U.S.-manufactured aircraft operating on an EASA registration, you typically need to comply with both FAA ADs (as the State of Design authority) and any EASA ADs issued for that type.

Step 2: Search by type certificate holder. The EASA portal organizes ADs by the TC holder name. For Cirrus aircraft, search under “Cirrus Design Corporation.” For older Cessna models, you may need to search historical TC holder names.

Step 3: Use the advanced filtering options. The EASA portal allows filtering by aircraft model, AD status (current, superseded, cancelled), and publication date range. Use these to narrow results to currently effective ADs.

Step 4: Check EASA AD status classifications. EASA ADs show applicability to aircraft on EU registries. If you’re operating a U.S.-manufactured aircraft on an EASA registry, verify whether the EASA AD adds requirements beyond the FAA AD or simply adopts it. Sometimes EASA sets different compliance timeframes.

Step 5: Review the National Aviation Authority position. Some NAAs issue additional guidance on AD compliance. Your local authority (CAA, DGAC, LBA, etc.) may have specific interpretations or approved alternative methods of compliance. Check their publications alongside the EASA AD compliance requirements.

Building Your AD Compliance List and Tracking Status

Once you’ve identified all applicable ADs, you need a system to track compliance status. Here’s what that system must capture:

For each applicable AD, document: the AD number, issue date, effective date, subject description, applicability statement (why it applies to your aircraft), compliance requirement (one-time, recurring, or terminated by modification), compliance status (open, complied, or not applicable), compliance evidence (work order, logbook entry, part number of installed modification), and next action due (for recurring requirements).

Organize by compliance category. Group ADs into: complied one-time (no further action), complied recurring (track next due), open (action required before next flight or by calendar/hours deadline), and not applicable (document the exclusion reason).

Review the list after any maintenance. When a component is replaced, check whether the new part changes AD applicability. Installing a replacement fuel pump with a different part number might bring new ADs into scope—or might comply with an AD terminating action.

Cross-reference with Service Bulletins. Many ADs reference manufacturer Service Bulletins as the compliance method. Track SB status alongside AD status. Some SBs become mandatory via AD; others remain optional but affect AD applicability if accomplished. For more background on the relationship between these documents, see our overview of finding airworthiness directives.

Audit before annual/100-hour inspections. Provide your IA or maintenance organization with your current AD list and compliance status before the inspection. This lets them verify your records against their search and flag any discrepancies. It also demonstrates you’re meeting your owner obligations under Part-91 or Part-ML.

Frequently Asked Questions

Q: How often are new airworthiness directives issued for GA aircraft?

The FAA issues roughly 300-400 ADs per year across all product categories, with a smaller subset affecting GA piston aircraft. EASA’s output varies but follows a similar pattern. New ADs can appear at any time—there’s no fixed schedule. Set up RSS feeds or email alerts from both rgl.faa.gov and ad.easa.europa.eu to catch new issuances relevant to your type. Checking monthly is a reasonable minimum for a GA owner.

Q: What happens if I discover an AD wasn’t complied with before I bought the aircraft?

The aircraft is technically unairworthy until the AD is complied with. You cannot legally fly it to maintenance—you’ll need to arrange compliance at the aircraft’s current location or obtain a ferry permit. For pre-purchase, this is why AD compliance verification is a standard part of any competent pre-buy inspection. If you missed it, address it now and document the correction in your maintenance records.

Q: Can my mechanic sign off an AD compliance, or does it require an IA?

Depends on the work required. If the AD calls for an inspection that doesn’t require disassembly beyond normal servicing, an A&P can perform and sign off the work under Part 43.3. If the AD requires an approval for return to service after a major repair or alteration, you’ll need an IA signoff. EASA rules differ—work must be performed under an approved maintenance organization structure as defined in your aircraft’s continuing airworthiness management arrangements.
