Both engines failed within a short interval 18 minutes after takeoff from Bario Airport, Malaysia, on a 35 minutes sector. The pilot attempted to land on a hillside jungle track used by timber transporters. The wings struck several trees causing the aircraft to impact nose down onto the hill slope.

Probable Cause:

The engines failed due to lack of fuel, resulting from the crew failure to ensure enough fuel for the flight. Contributory cause was the absence of a proper regulatory body to monitor the operator's activities through regular inspections and continuous surveillance.

Fuel starvation
All engine powerloss
Forced landing outside airport
