== Crash == |
|||
The airplane had arrived at Yerevan two hours before scheduled departure and was preparing for departure as flight B2-1834 from Yerevan (Armenia) to Minsk (Belarus) with 18 passengers and three crew. Refueling was done in automatic mode 25 minutes after landing, and 2,200 liters (1,802 kg) of Jet-A-1 fuel were added to the tanks. Due to reported reducing visibility at the main alternate airport, the crew decided to add another 400 liters of fuel about 30 minutes later during flight preparations. |
|||
The first officer performed the preflight check of the aircraft about 15 minutes after landing (and before refueling) and found all aerodynamics surfaces clean and dry by visual inspection as well as by touching the surfaces with the palm of his hand. The report <ref name="finalreportru">{{cite web |url=http://www.mak.ru/russian/investigations/2008/report_ew-101pj.pdf |title=Final Report of Belavia Flight 1834 |author=Interstate Aviation Committee (MAK) |date=2009-06-04 |accessdate=2009-08-31 |authorlink=Interstate Aviation Committee |url-status=dead |archiveurl=https://www.webcitation.org/64CfW2tFj?url=http://www.mak.ru/russian/investigations/2008/report_ew-101pj.pdf |archivedate=2011-12-25 }}</ref> mentioned that weather conditions that are susceptible to frost contamination require the pilot in command to perform the preflight walk-around. |
|||
The weather at the time was: winds from 110 degrees at {{convert|2|kn|km/h m/s|0}}, visibility 3500 meters (11500 feet) in light haze, clouds overcast at {{convert|2600|ft|m|order=flip|abbr=on}} scattered at {{convert|9800|ft|m|order=flip|abbr=on}}, temperature -3 °C, dew point -4 °C and QNH 1019 hPa. The crew computed [[V speeds]] of V<sub>1</sub> at {{convert|137|kn|km/h}}, V<sub>R</sub> at {{convert|139|kn|km/h}} and V<sub>2</sub> at {{convert|145|kn|km/h}}. After engine start the crew activated the anti-ice systems of the engines, but the wing anti-ice systems were not activated. |
|||
The airplane banked progressively left after liftoff until the left wing touched the ground with the airplane veering left of the runway, rolled right separating the right hand wing, crossed the runway rolling on its back and disintegrated coming to rest right of the runway. Leaking fuel triggered a ground fire, which was quickly brought under control by the airport fire fighters.<ref name="FG15"> |

Initial speculation pointed to icing on the wings which caused the left wing to stall upon lift-off. Icing conditions were reported at the airport during the crash, and the CRJs are very prone to wing contamination and icing since they do not have any leading edge devices.<ref name="tannerpaper">{{Cite book |url=http://www.sae.org/technical/papers/2007-01-3286 |contribution=The effect of Wing Leading Edge Contamination on the Stall Characteristics of aircraft |last=Tanner |first=Clinton E. |title=SAE Aircraft and Engine Icing International Conference, Session: Airplane De / Anti-icing Operations - Part I |doi=10.4271/2007-01-3286 |date=September 2007 |publisher=SAE |place= Seville, Spain}}</ref> |

The [[Interstate Aviation Committee|Interstate Aviation Committee (MAK)]] performed a test employing a CRJ-900 registration {{airreg|D|ACKK}} to assess the accumulation and freeze of atmospheric moisture with large temperature differences between the ambient air and the remaining fuel in the tanks after landing. It was found that ice accumulated on the underside of the wing immediately after landing and grew 25 minutes after landing upon refueling. The upper side of the wing showed dew accumulation after refueling. The fuel temperature at the time of arrival was measured at -21 °C, and before departure at -12 °C with an ambient temperature of plus 8 °C. |

At the time of the accident it could therefore be assumed that the temperature of the fuel in EW-101PJ never got above -12 °C with an ambient temperature of -3 °C. |

⚫ | |||
=== Final report === |
|||
The [[Interstate Aviation Committee|Russian Interstate Aviation Committee (MAK)]] released their final report in Russian<ref name="finalreportru"/> which concluded that the most probable cause of the accident was: |
|||
* The asymmetric loss of aerodynamics properties of the wing during takeoff, which resulted in stalling the aircraft immediately after liftoff, the left wing contacting the runway and the subsequent destruction and fire. |
|||
* The reason for the loss of aerodynamics properties of the wing in the current weather conditions was frost contaminating the surfaces of the wings. The cause of the frost contamination was, most likely, the temperature difference of air and cold fuel in the tanks. |
|||
* Takeoff below the recommended safe speed for contaminated wings aggravated the situation. |
|||
* The current standard procedures to examine the aerodynamic surfaces before departure, along with the inefficiency, can not fully guarantee the preventions of similar accidents during takeoff in the future because of the high sensitivity of the wing, that does not permit even a slight contamination of the leading edge. |
|||
* Deicing of the wings as required by an Airworthiness Directive by Transport Canada (Canada's Civil Aviation Authority) in the actual weather conditions released after another similar accident most likely could have prevented the accident. |

Belavia Flight 1834 was a scheduled international passenger flight from Yerevan, Armenia, to Minsk, Belarus, operated by Belavia. On the morning of February 14, 2008, the Bombardier Canadair Regional Jet carrying 18 passengers and three crew crashed and burst into flames shortly after take off from Zvartnots International Airport near Yerevan, the capital of Armenia.
The captain was 50-year-old Viktor Shishlo, who had logged 9,215 flight hours, including 461 hours on the CRJ100. The first officer was 44-year-old Alexander Mukhin, who had 9,454 flight hours with 405 of them on the CRJ100.[2][3]
Fire and rescue crews were reportedly on site within 50 seconds after the crash. The passengers also helped the crew members out of the cockpit.[4]
None of the 21 occupants were killed, although seven passengers received serious injuries.[1]
Investigation
Initial speculation pointed to icing on the wings which caused the left wing to stall upon lift-off. Icing conditions were reported at the airport during the crash, and the CRJs are very prone to wing contamination and icing since they do not have any leading edge devices.[5]
Investigation teams from the General Department of Civil Aviation of Armenia, from Belarus, and from Bombardier participated in the investigation to determine the probable cause of the accident.[6]
