JAL B747SR accident, 1985

It was determined that the cause of this accident was MSD originating from a mis-repaired lap joint in the rear pressure bulkhead structure. An attempt was made to apply the presented approach in order to estimate a probable crack initiation scenario that might precede fatal MSD. Detailed fracture mechanics consideration of this issue may be found in the work by Terada, H., A Proposal on Damage Tolerant Testing for Structural Integrity of Aging Aircraft--Learning from JAL Accident in 1985, Fracture Mechanics: 25-th Volume, STP 1220, F.Erdogan,Ed., American Society for Testing and Materials, Philadelphia,1995.
