Airworthiness Directives; Airbus Model A320 and Model A321 Series Airplanes

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.
