Английская Википедия:Aeroflot Flight 7841
Шаблон:Short description Шаблон:Infobox aircraft occurrence Aeroflot Flight 7841 was a scheduled Soviet domestic passenger flight from Minsk to Leningrad (now Saint Petersburg), which crashed on 1 February 1985 killing fifty eight people on board.[1] Twenty-two people (including three crew members) survived the accident.[1] The crash was caused by engine failure brought on by ice ingestion. On 8 May 1985 the Tupolev Tu-134A was officially written off.[2]
Aircraft
The Tupolev Tu-134A, registration number CCCP-65910, serial number 63969, involved in the accident was manufactured on 11 May 1982 and had 448 completed flight cycles prior to the accident, having entered service on 8 June 1982.[2][1] Tu-134s are equipped with two tail-mounted Soloviev D-30 turbofan engines.[3]
Crash
Six seconds after takeoff, at an altitude of Шаблон:Convert and with a speed of Шаблон:Convert, a rapid loss of power occurred, accompanied by pops and Jet Pipe Temperature (JPT) overheating.[1] The crew levelled the wings and continued climbing, when the co-pilot reported a failure of the left engine to air traffic control.[1] At 65 seconds after takeoff, an excessive vibration alarm indicated failure of the right engine.[1] Then, at an altitude of Шаблон:Convert and a speed of Шаблон:Convert, the right engine failed, while the aircraft was still in the clouds.[1] In an attempt to retain speed, the captain initiated a descent with a vertical speed of Шаблон:Convert.[1] The aircraft was descending onto forest, with some trees up to 30 m in height.[1] At an altitude of Шаблон:Convert and with a five-degree right bank angle, the aircraft impacted the tree tops. The aircraft continued hitting the trees and ultimately burned down except the aft portion.
The crash site was located Шаблон:Convert east of Minsk National Airport by search groups after three hours.[4][1]
Investigation
The investigation concluded that both engines failed due to ice ingestion, which led to compressor stall, destruction of the compressors and over-temperature of the turbine blades.[1] Citing significant damage to the aircraft and engines, the investigators were unable to determine where the ice came from.[1]
