Abstract
This chapter presents the results of a fatigue test program, which also considers environmental and damage-tolerance aspects, conducted using specimens representative of wide-bodied commercial aircraft fuselage lap joints. The phenomenon of multi-site damage (MSD) in aircraft has been under examination by many in the aviation industry. This chapter investigates the feasibility of applying advanced bonding technology to commercial aviation structures containing MSD. The consequence of the undetected presence of MSD was dramatically illustrated through the in-flight failure of a fuselage lap joint on an Aloha Airlines B-737 aircraft on April 28, 1988. Essentially this failure occurred due to numerous small cracks along a fastener line linking together, causing the residual strength of the fuselage to be exceeded under pressurization. A test program was conducted to reproduce this type of failure, and an adhesively bonded boron/epoxy doubler for use as a repair or preventative measure has been developed.
