Airworthiness Directives; Airbus Model A320-111, -211, -212, - 214, -231, -232, and -233 Series Airplanes

摘要

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Airbus Model A320-111, -211, - 212, -214, -231, -232, and -233 series airplanes. This proposal would require repetitive ultrasonic inspections to detect fatigue cracking in the wing/fuselage joint cruciform fittings, and corrective actions, if necessary. 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 detect and correct fatigue cracks on the wing/fuselage joint cruciform fittings, which could result in reduced structural integrity of the wing/fuselage.
