Circumstances:
Aircraft was being operated on a non schedule cargo flight from Wamena to Kenyam, Papua. Flight was conducted under VFR and the pilot reported to ATC that the planned altitude was 9,500 feet. On board the aircraft were two pilots, a manifested load of diesel drums and grocery items, and a non-manifested load of 25 bags of rice weighing 827 lbs (375 kilos). The aircraft took off from Wamena runway 15 at 1217LT and ETA at Kenyam was 1247LT. Aircraft crashed around 1230LT in an isolated and wooded area in the Pasema district, and was destroyed by impact forces and post impact fire. Both occupants were killed.
Probable cause:
Factors that contributed to the accident are as follows:
a. The aircraft was loaded to a weight in excess of the maximum certificated takeoff weight.
b. The aircraft climb performance was adversely affected by the aircraft being operated above the certificated maximum takeoff weight.
c. The aircraft approached high terrain along the proposed route at an altitude which was below that specified in the operator's route guide.
d. The aircraft entered a high rate of descent during a terrain avoidance maneuver.
e. Recovery from the abnormal flight path was not achieved before the aircraft collided with terrain.
