What happened
During the flight, the aircraft's engine suffered a mechanical failure which caused the propeller to detach from the unit. Following this loss of propulsion, the crew initiated a descent to lower their altitude and sought an alternative landing site. The crew attempted an emergency touchdown in the vicinity of Amele, located approximately 16 kilometers southwest of Madang.
Ultimately, the aircraft struck the ground near the Gogol River. The impact resulted in the airframe being damaged beyond repair. There were two fatalities and injuries reported among the occupants during the incident.
Findings
Investigations into the accident revealed that the aircraft was operating at a weight exceeding its maximum allowable limit. Specifically, the total weight of the aircraft was 300 pounds above the MTOW.
