ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for certain ATR—GIE Avions de Transport Régional Model ATR42-300, -320, -500, ATR72-201, and -212A airplanes and all ATR—GIE Avions de Transport Régional 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.
DATES:
This AD is effective January 13, 2026.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 13, 2026.
