Airworthiness Directive · Amendment 39-11073 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Model A320 series airplanes having manufacturer serial numbers 002 through 402 inclusive, on which Airbus Modification 20071 (reference Airbus Service Bulletin A320-26-1020, Revision 1, dated January 4, 1993) has been accomplished; except those airplanes on which Airbus Service Bulletin A320-26-1034, dated May 9, 1995; Revision 1, dated September 13, 1995; Revision 2, dated April 1, 1996; or Revision 3, dated December 5, 1997; has been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires an electrical continuity test of the discharge circuit for the cargo compartment fire extinguisher bottle to detect any cross-connection of the electrical wires in the cargo compartment discharge circuit, and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent incorrect distribution of fire extinguishing chemicals in the event of a fire in the cargo compartment, which, if unconfined, could spread beyond the cargo compartment.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
