To prevent failure of the smoke detection system to provide warning of a fire in the lavatory, accomplish the following:

(a) Within 450 hours time-in-service after the effective date of this AD, perform a close visual inspection to detect damage or blockage of the flexible hoses that connect the smoke detector to the air extraction duct in each lavatory, and to detect contamination of the hoses, air extraction ducting, hose/duct connection, or inlet grid, in accordance with Airbus Industrie All Operator Telex (AOT) 26-07, dated October 6, 1992.
(1) If any damaged hose is found as a result of the inspection required by paragraph (a) of this AD, prior to further flight, repair or replace the damaged hose, in accordance with the AOT. If any damaged hose is repaired, that hose must then be replaced with a new hose within 400 hours time-in-service following the repair.
(2) If any blocked hose or contaminated hose, air extraction ducting, hose/duct connection, or inlet grid is found as a result of the inspection required by paragraph (a) of this AD, prior to further flight, clean the blocked or contaminated part, in accordance with the AOT.

(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch.

(c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.
