What happened
During the initial climb phase following takeoff, the aircraft experienced a partial loss of power from the left engine. This loss of thrust was caused by a mechanical failure within the number 8 engine assembly cylinder. Witnesses observed the plane at an altitude of approximately 400 feet while it was in a 20-degree left bank, as the crew attempted to maneuver the aircraft back toward the departure airport.
As the flight continued, the bank angle increased significantly to 60 degrees, accompanied by a visible reduction in airspeed. While the aircraft was descending below 300 feet, the left wing dropped to a 90-degree angle and the nose pitched downward into a vertical descent. Although the aircraft appeared to recover elevator control and briefly leveled its flight path, it subsequently encountered a secondary stall. The aircraft struck the ground and was consumed by a post-crash fire. The accident resulted in two fatalities.
Findings
- The primary mechanical issue was the failure of the number 8 engine assembly cylinder.
- The secondary stall occurred following an attempt to level the aircraft after a steep bank and loss of airspeed.
