An aircraft crashed into flames on the runway shortly after takeoff, killing all 11 occupants. The accident was attributed to an overloaded condition affecting engine performance during initial climb.

What happened

Shortly after departing the runway, the aircraft encountered a critical failure while climbing between 200 and 300 feet above ground level. A fire broke out in the left engine, leading to an immediate loss of thrust. As the airplane stalled, it descended back onto the runway surface where it came to rest and burst into flames. The impact and subsequent fire resulted in the deaths of all 11 people on board, comprising two crew members and nine passengers.

Findings

The official investigation concluded that the primary factor in the accident was that the aircraft was operating above its maximum takeoff weight. This overloaded condition negatively impacted the performance of the port engine, which subsequently caught fire during the initial climb phase. Investigators also noted that a precipitated and incorrect trim adjustment by the crew, or potentially a structural failure resulting from the loss of the left engine's power, may have contributed to the stall and crash.

Probable cause

The aircraft was overloaded, which compromised the operation of the port engine that caught fire during the initial climb.
