Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-300, - 320, -500, ATR72-201, and -212A airplanes and all ATR--GIE Avions de Transport R[eacute]gional Model ATR72-102, -202, -211, and -212 airplanes. This AD was prompted by an inspection on the ATR final assembly line that found a fire extinguishing tube, located on the ceiling of the aft cargo compartment, disconnected from its sleeve. This AD requires a functional check of the aft cargo fire extinguishing system and applicable on-condition actions, if necessary. For certain airplanes, this AD also requires an additional functional check and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

Applicable airplanes are those identified in EASA AD 2025-0080, dated April 11, 2025, corrected April 23, 2025.

Whether AD 2025-23-04 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2025-23-04 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
