Abstract

This is a study for the improvement of the defected elevator spar in operating aircraft. The elevator spar web holes were analyzed to find out the cause of the cracks. The fatigue striations were observed and the cracks occurred by the repetitive stresses during the elevator works. Also the outboard connection structure of the elevator and horizontal stabilizer was more weak shape than the inboard. The design changes were recommended and the analyses were performed to verify the improvement of the changed shapes.
