Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320-111, -211, -212, and -231 series airplanes. This proposal would require repetitive inspections for fatigue cracking around the fasteners attaching the pressure panel to the flexible bracket at frame 36, adjacent to the longitudinal beams on the left and right sides of the airplane; and repair as necessary. This proposal would also provide an optional terminating action for the repetitive inspections. This action is necessary to detect and correct fatigue cracking around the fasteners attaching the pressure panel to the flexible bracket at the frame 36 adjacent to the longitudinal beams, which could result in reduced structural integrity and possible rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
