Airworthiness Directive 2021-20-09

What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2021-03- 03, which applied to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72 airplanes. AD 2021-03-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2021-03-03, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2021-20-09 applies to
Applies only to airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before October 9, 2020.
Whether AD 2021-20-09 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
