What happened
During the initial climb phase immediately following liftoff, the aircraft experienced an aerodynamic stall. This loss of lift caused the plane to descend and impact the ground near the terminus of the runway. The impact resulted in the total destruction of the airframe. There were three fatalities among the crew members on board.
Findings
Investigations into the accident identified significant deviations from standard operating protocols. It was determined that the flight crew did not complete the necessary pre-departure preparations according to the operator's established procedures. Specifically, the investigation concluded that the failure to follow the pre-departure checklist led to the elevator lock remaining engaged during the takeoff sequence.
