User:Whoop whoop pull up/Transwestern Airlines Flight 868

Transwestern Airlines Flight 868 was a scheduled U.S. passenger flight from Boise to Hailey, Idaho, operated by Sierra Pacific Airlines under contract to Transwestern Airlines. On 15 February 1983, the De Havilland Canada DHC-6 Twin Otter operating the flight crash-landed on Idaho State Highway 75 following a loss of elevator control resulting from improper maintenance, destroying the aircraft and injuring all eight occupants of the aircraft, seven of them seriously.

Accident
Flight 868 took off from runway 10L at Boise at about 1020 Mountain Standard Time, and the flight proceeded uneventfully to the vicinity of Hailey at a cruising altitude of 9,500 feet above mean sea level (AMSL). At around 1100, while descending through 6,000 feet AMSL (about 700 feet above ground level) over the town of Bellevue, two miles south of Friedman Memorial Airport, the captain, in accordance with the standard arrival procedure for a landing on runway 31, reduced engine power to slow his plane in preparation for landing. Normally, the nose-down pitching moment produced by the reduction in engine power and airspeed would by easily countered using the aircraft's elevators. However, when the captain of Flight 868 reduced power, he found himself unable to arrest the aircraft's pitchdown, with the control column moving throughout its range of travel with neither appreciable resistance nor appreciable elevator response.
