Airworthiness Directive · Amendment 39-10657 · Airbus Model A320 and Model A321 Series Airplanes
Airbus Model A320 and Model A321 Series Airplanes
Model A320 and Model A321 series airplanes, as listed below, certificated in any category: On which Airbus Modification 24497 has not been installed in production. Or On which Airbus Service Bulletin A320-52-1027, Revision 2, dated February 18, 1993, Revision 3, dated December 10, 1993, or Airbus Service Bulletin A320-52-1064, Revision 1, dated September 8, 1995; has not been accomplished.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 and Model A321 series airplanes, that requires repetitive inspections to verify proper installation of the plain bushings of the upper and lower connection links on the forward and aft passenger/crew doors, and correction of discrepancies. This amendment also requires installation of shouldered bushings on the frame segment used for attachment of the connection links or modification of the frame segment bushing (as applicable), which terminates the repetitive inspection requirements. This amendment is prompted by a report that, during an emergency evacuation of in- service airplanes, the left aft passenger/crew door jammed against the fuselage structure in a nearly closed position due to bushing migration. The actions specified by this AD are intended to prevent jamming of the passenger/crew door, which could delay or impede the evacuation of passengers during an emergency.
