Aeroperú Flight 603 was a scheduled flight from Miami International Airport in Miami, Florida to Comodoro Arturo Merino Benítez International Airport in Santiago, Chile (SCEL), with stopovers in Ecuador and Peru. On 2 October 1996, the plane flying the final leg of this flight crashed, killing all 70 people aboard. The pilots struggled to navigate the aircraft after the failure of all the plane's instruments. With the pilots unaware of their true altitude, the plane's wing hit the water and it crashed shortly afterward. The cause of the instrument failure was a maintenance worker's failure to remove tape covering the static ports necessary to provide correct instrument data to the cockpit. == Overview == On October 1, 1996, AeroPerú Flight 603 from Miami International Airport had landed at the Lima airport using a Boeing 727–200 because of technical problems with the Boeing 757 that normally flew this route. 180 passengers were on the first leg of the flight. 119 had deplaned, and the remaining passengers were transferred to the Boeing 757 after maintenance checks. On October 2, 1996, shortly after takeoff just past midnight, the Boeing 757 airliner crew discovered that their basic flight instruments were behaving erratically and reported receiving contradictory serial emergency messages from the onboard computer, such as rudder ratio, mach speed trim, overspeed, underspeed and flying too low. The crew declared an emergency and requested an immediate return to the airport.〔"Flying Blind", ''Mayday'' (TV series )〕 Faced with the lack of reliable basic flight instruments, constant contradictory warnings from the aircraft's flight computer (some of which were valid and some of which were not), and believing that they were at a safe altitude, 58-year-old Captain Eric Schreiber Ladrón de Guevara, a veteran pilot who had logged almost 22,000 flight hours,〔http://www.skybrary.aero/bookshelf/books/1719.pdf〕 and 42-year-old First Officer David Fernández Revoredo, who had logged almost 8,000 flight hours,〔 decided to begin descent for the approach to the airport. Since the flight was at night over water, no visual references could be made to convey to the pilots their true altitude or aid the pilots in the descent. Also, as a consequence of the pilots' inability to precisely monitor the aircraft's airspeed or vertical speed, they experienced multiple stalls, resulting in rapid loss of altitude with no corresponding change on the altimeter. While the altimeter indicated an altitude of approximately 9,700 feet, the aircraft's true altitude was in fact much lower.〔 The air traffic controller had instructed a Boeing 707 to take off and help guide the 757 back in to land, but before the 707 could take off, the 757's wingtip struck the water approximately 25 minutes after emergency declaration, making the pilots realize the true altitude of the airliner; the pilots struggled with the controls and managed to get airborne again for seventeen seconds, but the aircraft crashed inverted into the water. All 9 crew members and 61 passengers died. The pilots, distracted by the conflicting warnings, did not notice the radar altimeter after passing through 2,500 feet, according to the accident report. After the crash, recovery crews found 9 bodies floating; the rest of the bodies sank with the airliner.〔 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「Aeroperú Flight 603」の詳細全文を読む スポンサード リンク
