What happened
During the initial climb phase following departure from Wamena Airport, an aircraft encountered severe weather conditions characterized by low cloud cover and restricted visibility. While attempting to ascend, the aircraft collided with overhead power lines, which subsequently led to a crash and an immediate post-impact fire.
All three people on board, including the pilot and two other occupants, were killed in the accident.
Findings
Investigations into the accident indicated that the aircraft was unable to reach an adequate altitude following takeoff. The primary factor contributing to this failure to climb was that the aircraft was carrying an excessive load.
