1989年アメリカ海洋大気庁P-3エンジン喪失事故で航空機パイロットは死去した？
EgyptAir Flight 990 (MS990/MSR990) was a regularly scheduled flight from Los Angeles International Airport, United States, to Cairo International Airport, Egypt, with a stop at John F. Kennedy International Airport, New York City. On October 31, 1999, the Boeing 767 operating the route crashed into the Atlantic Ocean about south of Nantucket Island, Massachusetts, killing all 217 passengers and crew on board. The National Transportation Safety Board found that the probable cause of the accident was the airplane's departure from normal cruise flight and subsequent impact with the Atlantic Ocean as a result of the relief first officer's flight control inputs. The reason for the relief first officer's actions was not determined.
As the crash occurred in international waters, it was investigated by the Ministry of Civil Aviation's Egyptian Civil Aviation Agency (ECAA) under International Civil Aviation Organization rules. As the ECAA lacked the resources of the much larger U.S. National Transportation Safety Board (NTSB), the Egyptian government asked the NTSB to handle the investigation. Two weeks after the crash, the NTSB proposed handing the investigation over to the Federal Bureau of Investigation, as the evidence suggested that a criminal act had taken place and that the crash was intentional rather than accidental. This proposal was unacceptable to the Egyptian authorities, and hence the NTSB continued to lead the investigation. The NTSB concluded "not determined", while the ECAA determined that the incident was caused by mechanical failure of the aircraft's elevator control system.
