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 detect fatigue cracking of the lower surface panel on the wing center box; and repair, if necessary. This proposal also would require modification of the lower surface panel on the wing center box, which constitutes 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 prevent fatigue cracking of the lower surface panel on the wing center box, which could result in reduced structural integrity of the airplane.
