What happened
Approximately 18 minutes after departing from Bario Airport, the aircraft was operating at its cruising altitude when both engines ceased functioning. The loss of power was caused by the depletion of available fuel. In an effort to reach the ground safely, the crew initiated an emergency descent and landing procedure.
During the descent, the aircraft impacted a line of trees and came to rest in a forested region situated roughly 9 km from Long Seridan. The impact resulted in a high number of casualties. Out of the total occupants on board, 14 fatalities were recorded, which included both the pilot and the co-pilot. Six passengers were successfully rescued from the wreckage following the accident.
Findings
Investigations into the accident determined that the primary reason for the dual engine failure was fuel exhaustion.
