What happened
During a nighttime departure at approximately 80 mph, the aircraft experienced significant difficulty maintaining altitude. During the initial climb, the left wing made contact with an accumulation of ice. This impact caused the left main landing gear to be severed from the airframe. Following this structural damage, the aircraft entered a bank from left to right.
As the flight continued, the right wing also struck an ice heap. These successive impacts led to an aerodynamic stall, causing the plane to crash. The wreckage came to rest 800 meters past the end of the runway. The incident resulted in two injuries involving the captain and the flight engineer, while the remaining five occupants on board escaped without harm. Due to the extent of the damage, the aircraft was declared a total loss and left at the crash site.
Findings
Investigators noted that the pilot exhibited an overconfident and dismissive demeanor prior to the departure. The primary factor in the accident was the impact with ice accumulations during the takeoff phase.
