## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 B2, A300 B4, A300 B4-600, and A300 B4-600R series airplanes, and Model A300 F4-605R airplanes. This AD requires repetitive inspections for cracking of certain fittings, corrective action if necessary, and, for certain airplanes, a modification. This AD also provides an optional terminating action for the repetitive inspections. The actions specified by this AD are intended to detect and correct propagation of cracks on the frame 40 aft fittings due to local stress concentrations at the upper flange runout of frame 40, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
