Abstract

A failed pipe fastener assembly of an aircraft was analyzed. Failure pattern suggest that the two haves of the pipe fastener got detached by deforming the sheet material at the bolted region due to forces exerted from inside. Examination revealed that surfaces of a few other parts of the assembly were in touch with the sheet material. However, it was not possible to establish whether or not any assembly related issues were responsible for the failure. Evidences do not suggest any metallurgical abnormalities in the material of construction as the cause of failure.
