@amazeifystore: One repair detail. Seven years of pressure. A catastrophic failure. After a 1978 tail strike, a faulty bulkhead repair weakened under repeated pressurization. In 1985, the bulkhead ruptured, damaging the tail and hydraulic lines of JAL Flight 123. What engineering failure should we investigate next? #JAL123 #AviationSafety #EngineeringFailure #ForensicEngineering #AircraftMaintenance #AviationHistory #StructuralFatigue #Engineering
