Airworthiness Directives; Airbus Model A300 B2, A300-B2K, A300 B4-2C, A300 B4-100, and A300 B4-200 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B2, A300 B2K, A300 B2-200, A300 B4, A300 B4-100, and A300 B4-200 series airplanes, that currently requires certain structural inspections and modifications. This amendment requires that those inspections be accomplished on additional airplanes. This action also requires new repetitive inspections for airplanes in certain configurations at revised thresholds and intervals. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct corrosion and cracking of the wings and fuselage, which could result in reduced structural integrity of the airplane.
