LANSA Flight 502 was a Lockheed L-188A Electra operated by ''Líneas Aéreas Nacionales Sociedad Anónima'' (LANSA) which crashed shortly after takeoff from Quispiquilla Airport near Cusco, Peru on August 9, 1970, after losing all power from one of its engines.〔(【引用サイトリンク】title=Accident record )〕 The four-engine turboprop aircraft, registered OB-R-939, was bound from Cusco to Lima, carrying 8 crew and 92 passengers. All but one of the occupants died from injuries sustained from impact forces and post crash fire. Two people on the ground were also killed. There were 49 American high school exchange students on board, all of whom perished.〔(【引用サイトリンク】accessdate=2009-06-18 )〕 A Peruvian government investigation concluded that the accident was caused by improper execution of engine-out procedures by the flight crew, aggravated by lack of maintenance and overloading. LANSA was fined and its operations were suspended for 90 days. At the time, the crash was the deadliest ever in Peruvian history.〔 ==Background== More than half of the passengers belonged to a single group, sponsored by the Buffalo, New York based International Fellowship student exchange program, consisting of 49 American high school exchange students, along with their teachers, family members, and guides, who were returning from a visit to nearby Machu Picchu to their host families in the Lima area. The daughter of the mayor of Lima was also accompanying the group. The Peruvian passengers included a couple on their honeymoon.〔("Peru: 99 People Killed in Air Crash" ). ITN Source Article, August 15, 1970.〕 August 9, 1970 was a Sunday, and Flight 502 was originally scheduled to depart Cuzco at 8:30 am,〔(【引用サイトリンク】title=1968 LANSA Flight Timetable )〕〔Note that LANSA 1968 flight timetable shows 10:15 am as 'daily' departure time of Flight 502 from Cuzco to Lima, although NYT article reports it was scheduled as 08:30 am for flight 502.〕〔 but since many of the members of the American group wanted to visit the nearby Pisac native handicraft market prior to leaving for Lima, the airline postponed the departure time to 2:45 pm. Quispiquilla Airport, since renamed to Alejandro Velasco Astete International Airport, is located about east-southeast of the city of Cusco, in a small valley high on the Andes, at an altitude of above mean sea level.〔(【引用サイトリンク】title=CUZ - Cuzco, Perú - Velazco Astete )〕 Higher mountainous terrain surrounds the single east-west runway airport in all directions. Since it was August, it was winter time in Peru, as in the rest of the southern hemisphere. At about 2:55 pm, the four-engine Electra turboprop began its takeoff run to the west. At some point during the takeoff run or initial climb, the number three engine〔Number three engine is inboard, right side.〕 failed and caught fire. The crew continued the takeoff and climb, per standard procedure, using power from the remaining three engines. The pilot radioed the control tower declaring an emergency, and the control tower cleared the flight for an immediate landing.〔 The number three engine was engulfed in flames as the crew retracted the flaps and maneuvered the plane into a left turn back to the runway.〔 The plane entered a 30–45 degree bank, then rapidly lost altitude and crashed into hilly terrain about west-southwest of the runway, above the village of San Jerónimo. All aboard perished except the copilot, who was found in the wreckage of the cockpit badly burned but alive. Two farm workers were killed on the ground. 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「LANSA Flight 502」の詳細全文を読む スポンサード リンク
