Aeroflot Flight 821, operated by Aeroflot-Nord in a service agreement with Aeroflot and as its subsidiary, crashed on approach to Perm Airport on 14 September 2008 at 5:10 local time (UTC+06). All 82 passengers and 6 crew members were killed. A section of the Trans-Siberian Railway was damaged by the crash. Flight 821 is the deadliest accident involving a Boeing 737-500 to date, surpassing the 1993 crash of Asiana Airlines Flight 733 and the second-deadliest aviation incident in 2008, behind Spanair Flight 5022. The main reason for the crash was that both pilots had lost spatial orientation due to their lack of proficiency with the Western type of attitude indicator on the aircraft. Fatigue from lack of adequate rest, poor CRM and possible alcohol consumption by the captain also contributed to the accident. This air disaster resulted in the rebranding of Aeroflot-Nord into Nordavia, effective on 1 December 2009. == Accident == The Boeing 737–505, registration VP-BKO, an aircraft belonging to the Aeroflot subsidiary Aeroflot-Nord but operating as Aeroflot flight SU821〔 〕 from Moscow's Sheremetyevo International Airport to Perm (Russia) crashed into a railway line southwest of Perm 5:10 AM local time (or 13 September 2008, 23:10 UTC).〔Final report, synopsis (page 8).〕〔 〕〔 〕〔 〕〔 〕 The weather at the time of accident was rainy (unbroken clouds at 240 m, light rain).〔 (【引用サイトリンク】work=Aviation Herald )〕 According to an interview given by the air traffic controller shortly after the disaster, the crew did not respond correctly to ATC commands: after going around, it turned eastward instead of turning westward. However, the crew reported no emergency onboard and confirmed all commands given by ATC.〔 〕 At 5:10 AM, radio contact with the plane was lost; minutes later it crashed in the outskirts of Perm. Aeroflot-Nord officially stated that: "The Boeing-737 carried 82 passengers on board — including 7 children — and 6 crew... All passengers were killed. As the plane was coming in for landing, it lost communication at the height of and air controllers lost its blip. The airplane was found within Perm's city limits completely destroyed and on fire." Investigator Vladimir Markin said that "there were 82 passengers plus a baby and 5 crew on board, and by preliminary information, they are all dead as the airplane fell into a ravine near the city limits." RIA Novosti however reported that "it was possible that 3 people who bought a ticket for the ill-fated flight 821 to Perm did not get on board." Both flight recorders were found and successfully decoded. The airline stated "it pledged to pay compensation on obligatory accident insurance in full, which would make up to 2 million rubles per victim." The crash damaged and shut down a section of the Trans-Siberian Railway; rail traffic was temporarily re-routed via Chusovaya station, and was restored by the evening of 14 September. The aircraft was leased by Aeroflot-Nord from Dublin-based Pinewatch Limited from July 2008 to March 2013.〔 〕〔 〕〔 〕 It was reported that its engines caught fire at an altitude of . Eyewitness reports stated that the plane was visibly on fire prior to crashing, and hit the ground at a 30–40-degree angle.〔 However, the low clouds (at 240 m) must have prevented any witnesses from seeing the plane for more than a few seconds and the report was subsequently discounted by the accident enquiry (see below). The final enquiry report stated that "after the base turn, approaching the landing course at 600 m with both autopilot and autothrottle disengaged, the aircraft started climbing up to 1300 m, rolled 360° over the left wing and collided with 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「Aeroflot Flight 821」の詳細全文を読む スポンサード リンク
