Abstract
During refurbishing of a pilotless target aircraft after a sortie, the hinge pins which connect the elevator to a connecting flange was found broken on both port and starboard sides. These pins had been cadmium plated. Electron fractography indicated that the failure of the pins was due to hydrogen embrittlement. Also the hinge pins did not conform to material specifications.
