After the total failure of all four hydraulic systems, a no longer controllable Boeing 747-100 of Japan Air Lines hit a mountainside. The accident was caused by the fracture of the rear pressure bulkhead as a result of an assembly error. As a result of the break, the pressurized cabin air suddenly escaped into the tail unit area, whereby parts of the vertical tail unit were torn off and the hydraulic lines running there were cut. The accident is the most serious flight accident to date with only one crashed aircraft.
