Summary
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 detect cracking in the inner flange of door frame 66, and corrective actions, if necessary. This proposal also would provide for an optional terminating action for the repetitive inspections. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to correct such fatigue cracking, which could result in reduced structural integrity of the airplane.
