Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300 B2 and B4 series airplanes, that currently requires inspections for cracks of the fuselage, wings, and vertical stabilizer structures; and repairs or modifications, if necessary. That AD was prompted by reports of cracking in several areas of the fuselage, wings, and vertical stabilizer structure due to fatigue-related stress. The actions specified by this AD are intended to prevent such fatigue-related cracking, which could result in reduced structural integrity of the fuselage, wing, and vertical stabilizer. This action provides for a new optional terminating action, for certain airplanes, and expands the applicability of the existing AD to include additional airplanes.
