When is a mechanic responsible for checking AD compliance?

• A. When performing an inspection required under part 91, 125, or 135.
• B. During an annual inspection.
• C. At any time during maintenance.
• D. Only at initial certification.

Answer: (A)

Airworthiness Directives are mandatory actions issued by the FAA to correct unsafe conditions. A mechanic is responsible for verifying AD compliance whenever performing inspections that are required under the regulations, specifically those conducted under Part 91, Part 125, or Part 135. These inspections are the formal checkpoints where the aircraft’s airworthiness status is reviewed and certified, so ensuring that all applicable AD actions have been completed is part of keeping the aircraft airworthy. ADs may require actions at specific intervals or conditions, and they must be documented in the maintenance records before the aircraft can be returned to service. While AD checks occur during maintenance in general, the standardized trigger is the inspections mandated by those parts; it’s not limited to annual inspections or to initial certification.
