British Airways Flight 268 was a regularly scheduled flight from Los Angeles' LAX airport to London Heathrow. The flight took off at about 9:24 p.m. on 20 February 2005. When the plane, a four engine Boeing 747–436, was about 300 feet into the air, flames burst out of its number 2 engine, a result of engine surge. The pilots shut the engine down. Air traffic control expected the plane to return to the airport and deleted the flight plan. However, after consulting with the airline dispatcher, the pilots decided to set off on their flight plan "and get as far as we can" rather than dump 70 tonnes of fuel and land. The 747 is certified to fly on three engines. Having reached the East Coast, the assessment was that the plane could continue safely. The cross-Atlantic journey encountered less favourable conditions than predicted. Upon reaching the UK, believing there to be insufficient usable fuel to reach their destination, the captain declared an emergency and landed at Manchester Airport. A safety controversy ensued; the US Federal Aviation Administration (FAA) accused the carrier of flying an "unairworthy" plane across the Atlantic ocean. The FAA proposed fining the carrier, British Airways (BA) $25,000. BA lodged an appeal on the grounds that they were flying according to United Kingdom Civil Aviation Authority (CAA) rules (which are derived from International Civil Aviation Organisation standards).〔Learmount, David (11 April 2006) ("British Airways appeals FAA fine over 2005 Boeing 747 engine shutdown 'safety breach'" ). ''Flightglobal.com''〕 In the end, the FAA told BA it was dropping the case based on assurances that airline changes will "preclude the type of extended operation that was the subject of this enforcement action." BA said they hadn't changed their procedures and according to ''Flight International'' the FAA said that they "will recognise the CAA's determination that the aircraft was not unairworthy"〔Learmount, David (23 January 2007) ("USA/UK fail to agree new engine-out rules" ). Flightglobal.com〕 The investigation report recommended that BA revise its training of crews in three engine operation fuel management procedures. During the investigation, the British Air Accidents Investigation Branch discovered that one of the eight tracks on the Flight Data Recording tape had been erased during flight as a result of a short circuit in the unit, resulting in the loss of over three hours of data. It recommended that the FAA should require Honeywell, the manufacturer of the flight data recorder, to include a visual inspection of the printed circuit board during routine maintenance of the FDR. The flight number remains the same but the airline mainly uses Airbus A380-800 on this route. == References == 〔 * 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「British Airways Flight 268」の詳細全文を読む スポンサード リンク
