A Laboratory Study of Multiple Site Damage in Fuselage Lap Splices

Abstract

This report details an experimental study that was conducted to explore the causes of fuselage lap splice multiple site damage (MSD), which has been observed in several aging aircraft. MSD was partially responsible for the 1988 Aloha Airlines accident. A specimen was designed and tests were conducted to investigate the effects on MSD and fatigue of: (1) a terminating action repair; (2) simultaneous tension and shear; and (3) stress and several lap splice configurations. The results of over 120 tests were supported by finite element analysis, strain gage studies and statistics. Fatigue, Life, Fuselage lap, Biaxial stress, Bucktail diameter.
