What happened
During the takeoff roll, the co-pilot initiated rotation once the aircraft reached a speed of 290 km/h. After lifting off, the aircraft type reached an altitude of approximately 7 metres before banking 3.5 degrees to the left. Following a distance of 665 metres, the aircraft entered a critical angle of attack and the nose pitched up to 35 degrees. At this moment, the landing gear had just been retracted.
The aircraft descended back onto the runway surface, sliding on its belly for an additional 270 metres. The movement ended approximately 120 metres to the left of the runway centerline. While all 25 occupants were successfully rescued from the wreckage, two individuals sustained serious injuries. The aircraft was subsequently declared a total loss due to damage beyond repair.
Findings
Investigations revealed that the captain had elected to occupy the right-hand front seat, leaving the co-pilot in command of the left-hand seat. This arrangement violated established procedures because the co-pilot lacked the necessary authorization and sufficient experience for such a role.
A primary factor in the accident was that the co-pilot failed to extend the flaps to the required takeoff angle. This configuration error led to the aircraft reaching a critical angle of attack and stalling shortly after liftoff. The incident was further compounded by poor crew coordination, a failure to adhere to the pre-takeoff checklist, and an inability to identify that the aircraft was improperly configured for departure.
