Failure analysis of a CH-47 horizontal hinge pin assembly, P/N 114RS226 /

A CH-47D horizontal hinge pin assembly was examined to determine the root cause of ring and roller fracture and spalling. Chemical analyses, metallography, and hardness testing indicated that the rings and rollers conformed to the material requirements of the governing drawing. Metallography and vis...
