Abstract

A few components retrieved from the wreckage of a helicopter were sent to the laboratory for investigation. Examination revealed that all these components have failed by overload, probably under impact forces. None of the failed components showed evidences of delayed or progressive failure such as fatigue or stress corrosion cracking. The damage marks observed on the leading edge of the main rotor blade suggests that it had impacted with metallic wire rope or cable.
