What happened
During the descent toward Rajshahi Airport, the aircraft experienced a mechanical failure involving the left engine. This loss of power led to an aerodynamic stall, causing the plane to descend into a field situated a short distance before the runway threshold. The impact resulted in the total destruction of the aircraft and caused four fatalities among the crew.
Findings
Investigations into the accident identified several contributing factors related to engine performance and pilot response. The starboard engine suffered from overheating and malfunctioned, which eventually led to the detachment of three cylinder heads while the aircraft was operating on a single engine under a heavy load. Furthermore, the investigation concluded that the pilot failed to execute appropriate emergency procedures following the initial failure of the port engine, a situation exacerbated by fatigue.
