Inside The Deadliest Single-Aircraft Disaster Ever | Last Moments
It’s the worst single-aircraft accident in aviation history – and there’s a picture from a passenger’s point of view.
“Japan Air Lines Flight 123 (JAL123) was a scheduled domestic Japan Air Lines passenger flight from Haneda Airport in Tokyo to Itami International Airport in Osaka. On August 12, 1985, the Boeing 747SR operating this flight suffered a sudden decompression 12 minutes into the flight, and crashed in the area of Mount Takamagahara, Ueno, Gunma Prefecture, 100 kilometres (62 mi; 54 nmi) from Tokyo 32 minutes later. The crash site was on Osutaka Ridge, near Mount Osutaka.
Japan’s Aircraft Accident Investigation Commission (AAIC) concluded,[1]: 129 agreeing with investigators from the U.S. National Transportation Safety Board, that the rapid decompression was caused by a faulty repair by Boeing technicians after a tailstrike incident during a landing at Osaka Airport in 1978 as JAL Flight 115. The rear bulkhead of the plane had been repaired with an improperly installed doubler plate, compromising the plane’s airworthiness. Cabin pressurization continued to expand and contract the improperly repaired bulkhead until the day of the accident, when the faulty repair failed, causing a rapid decompression that ripped off a large portion of the tail and caused the loss of hydraulic controls to the entire plane.
The aircraft, which was configured with increased economy-class seating, was carrying 524 people. All 15 crew members and 505 of the 509 passengers died in the accident. Some of the passengers survived the initial crash but died of their injuries hours later while awaiting rescue. Surpassing the fatalities of All Nippon Airways Flight 58, which crashed 14 years earlier with 162 fatalities, it is the deadliest single-aircraft accident both in Japan and global aviation history.
The event is known in Japan as The crash accident of Japan Air Lines Jumbo Jet (Japanese: 日航ジャンボ機墜落事故).”
