The Lokomotiv Yaroslavl air disaster occurred at 4:05 P.M. Moscow Time on Wednesday, September 7, 2011, when Yak-Service Flight 9633, a Yak-Service Yakovlev Yak-42, carrying the players and coaching staff of the Lokomotiv Yaroslavl professional ice hockey team, crashed near the Russian city of Yaroslavl. The aircraft ran off the runway before lifting off, struck a tower mast, caught fire and crashed from Tunoshna Airport at the Volga River bank. Of the 45 on board, 43 died at the crash site. One of the two rescued from the wreck, Alexander Galimov, died five days later in hospital.〔 Only the avionics flight engineer, Alexander Sizov, survived. Lokomotiv Yaroslavl, a member of the Kontinental Hockey League (KHL), Russia's top ice hockey league, was on its way to Minsk, Belarus, to start the 2011–12 season.〔 All players from the main roster and four from the youth team were on board the aircraft. Because of the tragedy, Lokomotiv Yaroslavl chose to cancel their participation in the 2011–12 KHL season. The club instead participated in the 2011–12 season of the Russian Major League (VHL), the second-ranked ice hockey league in Russia after the KHL, starting in December 2011, and were eligible for the VHL playoffs. The KHL temporarily suspended its season-opening game already in progress and postponed the start of the season by five days. Investigation of the crash focused on pilot error and technical failures. An investigative committee was set up which examined Yak-Service's records, conditions at the airport, plane wreckage and flight recorder data. Simulations of the plane takeoff were held to compare with recovered flight recorder data. Testing determined that pilot error was the cause as a braking force was found to have been applied by the chief pilot during takeoff. The investigating committee released its report at a press conference on November 2, 2011. According to Alexei Morozov, chief of the investigative commission: "the immediate cause of the Yak-42 plane crash was the plane crew's erroneous actions, namely the pilot stepping on the brake pedals before raising the nose wheel because of the wrong position of the feet on the brake platforms during takeoff." It was later revealed that the pilots had used falsified documents to obtain permission to fly the aircraft, and that they lacked the training necessary to fly the Yak-42. In addition, the co-pilot had undergone treatment for a nerve disease and was forbidden to fly. Investigators say he did not feel his foot on the brake, leading to the crash.〔 ==Crash== Weather conditions at Tunoshna Airport on September 7, 2011, were described as good, with a wind from 360° at , a visibility of , with significant stratocumulus clouds at a lower limit of .〔 The temperature was .〔 The Yak-Service Yak-42D aircraft entered Runway 05/23 at taxiway 5, from the start of the runway. Runway 05/23 is long, leaving for take-off. The aircraft was cleared for take-off. It accelerated to an estimated but failed to lift off from the runway.〔 The plane ran off past the end of the runway for a distance of before it lifted off from the ground.〔 From that point, the plane struck a beacon tower mast located about from the end of the runway. The plane did not reach a flying altitude, never exceeding an estimated from the ground.〔 After it struck the tower mast, the plane veered left and crashed on the riverbank of the Tunoshna River, from where it joins the Volga River, losing its tail assembly on impact while the front part of the jet disintegrated.〔 At the impact site, the tail section remained in the water, while the pieces of the fuselage were on dry land. The location of the wreckage was approximately from the end of the runway.〔(【引用サイトリンク】url=http://aviation-safety.net/database/record.php?id=20110907-0 )〕 Witness reports described the plane as "bursting into flames" after hitting the mast. The airplane's direction changed after hitting the mast, described as "rolling to the left" and then the plane impacted the ground. Another witness report described that the plane's engines went silent moments before the crash. Another report indicated that the plane hit some trees before it crashed. Another report indicated that the plane broke into two before impacting.〔 A security surveillance camera mounted on the mast recorded the approach of the airplane at high speed, running off the end of the runway, only metres above the ground, the nose pulling up moments before impacting the mast. Debris from the aircraft was found just past the mast site, continuing from that point to the crash site.〔 The plane's crew did not report any technical problems to the airport controllers.〔 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「2011 Lokomotiv Yaroslavl air disaster」の詳細全文を読む スポンサード リンク
