The World - News from Sept. 15, 1985

Japanese investigators confirmed that a rear pressure bulkhead suspected of causing the Japan Air Lines crash last month was incorrectly repaired by Boeing Co. in 1978 and showed signs of metal fatigue. But the Transport Ministry committee, in its second report on the crash of the Boeing 747-SR, contradicted the account of the faulty repair issued a week earlier by Boeing. The report did not specify the cause of the crash, which killed 520, but said the faulty repair allowed abnormal stress on a single row of rivets rather than the required three rows.
