(e) Unsafe Condition 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. The FAA is issuing this AD to address this condition, which if not detected and corrected, could affect the capability of the aft cargo compartment fire extinguishing system to contain a cargo compartment fire. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2025-0080.

(4) This AD does not adopt the "Remarks" section of EASA AD 2025-0080. (i) Special Flight Permits Special flight permits may be issued in accordance with 14 CFR 21.197 and 21.199 to operate the airplane to a location where the airplane can be modified, provided no cargo is in the aft cargo compartment.
