What happened
On the early morning of the accident, a Canadair CRJ100ER operated by Belavia arrived at Yerevan-Zvartnots Airport (EVN) from Minsk-2 International Airport. Following the arrival of flight BRU1833, the aircraft underwent refueling and flight planning procedures. Prior to departure, the pilot performed a visual and tactile inspection of the tail assembly and critical wing surfaces, noting that all components were dry and clean.
At approximately 04:08, the crew initiated engine starts. While the cowl anti-ice system was activated, the wing anti-icing system remained inactive. The aircraft taxied to runway 27 and received clearance for takeoff. During the takeoff roll, the aircraft experienced a progressive left bank, leading to the left wing tip making contact with the runway surface. This contact caused the aircraft to veer off the side of the runway, rolling to the right. The impact resulted in the separation of the right wing and a subsequent fuel fire. The aircraft eventually came to a stop in an inverted position. There were 21 survivors (three crew members and eighteen passengers) following the incident.
Findings
- The aircraft experienced a significant left bank during the takeoff phase.
- The wing anti-icing system was not activated prior to departure.
