On 26 June 1950, a Douglas DC-4 Skymaster aircraft departed from Perth, Western Australia for an eight-hour flight to Adelaide, South Australia. It crashed 18 minutes after take-off, from Perth Airport. All but one of the 29 occupants were killed in the accident and the sole survivor died six days later. It was the worst civil aviation accident in Australia.〔("28 Killed In Australia’s Worst Air Disaster: Survivor Badly Burned" ) ''The Sydney Morning Herald'' – 28 June 1950, p.1 (National Library of Australia) Retrieved 22 September 2012〕〔("Twenty-Eight Lives Lost In Air Crash" ) ''The West Australian'' – 28 June 1950, p.1 (National Library of Australia) Retrieved 22 September 2012〕〔(Aviation Safety Network ) Retrieved 22 September 2012〕 As the aircraft flew eastwards over the outer suburbs of Perth numerous witnesses observed that it was flying at a lower altitude than usual for the daily Skymaster services, and at least one of the engines was running roughly and backfiring at regular intervals. In the minutes before it crashed, witnesses heard a number of different engine noises – sometimes operating normally, sometimes all engine noise ceased, only to be replaced by a very loud, high-pitched scream. When the wrecked engines were examined many weeks after the accident a significant amount of corrosion product was found in the fuel system within two of the engines. After a preliminary investigation, Investigators from the Department of Civil Aviation believed the water responsible for the corrosion was also responsible for rough running of at least one engine, and ultimately temporary loss of power from all engines on at least one occasion. The Investigators did not find a likely source for the water. All but one of the 29 occupants on board the aircraft died, either from multiple injuries and burns, or from incineration. One elderly male passenger survived the crash. The first rescuers at the crash site found him wandering about, dazed and distressed. He suffered serious burns and was admitted to hospital where he died six days later. The accident became the subject of an Inquiry chaired by a Supreme Court judge. In the absence of evidence indicating the source of any water in the fuel, the Inquiry dismissed the submission that water was responsible for the accident. The Inquiry did not determine the cause of the accident but it made recommendations to enhance the safety of aircraft operations. ==The flight== Photo Frank Leyden 1948 (NLA) The aircraft was the ''Amana'', a Douglas DC-4-1009 registered VH-ANA and the flagship of the Australian National Airways fleet. It flew for the first time on 28 January 1946 and was flown to Australia on 9 February 1946.〔〔("Aussie Airliners" ) Retrieved 22 September 2012〕 The ''Amana'' departed from Perth Airport at 9:55 pm for the 8-hour flight to Adelaide. On board were 24 passengers, 3 pilots and two air hostesses.〔 A radio report was received from the ''Amana'' at 10:00 pm advising it was on course and climbing to 9,000 feet. Nothing more was heard from the aircraft.〔〔("Mysterious Aspects Of Air Crash" ) ''The West Australian'' – 28 June 1950, p.4 (National Library of Australia) Retrieved 22 September 2012〕 As it flew east over the outer suburbs of Perth numerous people on the ground observed that it was flying unusually low, and heard at least one of its engines running roughly and backfiring repeatedly.〔〔〔("Witnesses Tell Of Air Disaster" ) ''The West Australian'' – 8 February 1951, p.3 (National Library of Australia) Retrieved 22 September 2012〕 ''Amana'' crashed at about 10:13 pm.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1950 Australian National Airways Douglas DC-4 crash」の詳細全文を読む スポンサード リンク
