What happened
A cargo flight traveling from Singapore-Seletar Airport to Pontianak vanished during its transit. The aircraft, a twin engine plane, was transporting engine spare parts at the time of the incident. The flight was operated with a total of three crew members on board.
Approximately 65 minutes after takeoff, the captain contacted Air Traffic Control to report that the right engine had failed. Following this communication, the aircraft began a controlled descent at a rate of 200 feet per minute. The final radio transmission from the aircraft occurred when it reached an altitude of 3,500 feet.
Search efforts later identified a crash site in the sea, located roughly 128 km west of Pontianak within the Batu Islands region. While some debris was discovered floating on the water's surface, there was no trace of the three occupants found at the scene.
Findings
The investigation noted that the flight was experiencing an engine failure prior to the loss of contact with Air Traffic Control.
