1. Introduction
An internal angle fitting related to center box of Airbus A-300 submitted for failure investigation, which is shown in Fig. 1. This component was a structural component of a 14-year-old commercial jetliner that had carried out approximately 19,000 flight cycles when the crack was detected through NDT implementation. This type of aircraft is mostly utilized by cargo airlines. The aircraft had been grounded for service, and specific NDT operation had been implemented according to manufacturer service bulletin which notifies all operators of A-300 to conduct this test for those aircrafts that their flight cycles exceeds 17,000 cycles [1]. NDT detected a crack between two fastener holes in a way that affect residual strength of the part. Airbus had issued a service bulletin to replace this component with a modified substitute. The location of the component in the airframe is illustrated in Fig. 2. As an independent failure investigation, metallurgical properties of the angle had been studied with tests, corresponding scientific data had been gathered, and failure causes had been clarified.
