Airworthiness Directives; Airbus Model A320 Series Airplanes
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320 series airplanes. This proposal would require 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, if necessary. This proposal would also require replacement of the shouldered bushing on the locking mechanism with a new oversized bushing, which would terminate the repetitive inspection requirements. This proposal 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 the proposed AD are intended to prevent jamming of the passenger/crew door, which could delay or impede the evacuation of passengers during an emergency.
