What happened
During the initial climb phase following departure from Sampit Airport, the aircraft experienced a significant mechanical issue when the right engine lost power. In response to the engine failure, the crew attempted to execute a left turn to facilitate an emergency return to the departure airfield.
During this maneuvering process, the aircraft type experienced an aerodynamic stall. This led to the subsequent impact in the Mentaya River. The accident resulted in 3 fatalities, including both pilots and one passenger, while the remaining 7 occupants sustained injuries.
Findings
- The loss of power in the right engine during the climb phase initiated the emergency.
- The aircraft entered a stall during the crew's attempt to return to the airport via a left turn.
