What happened
Following its departure from Samarinda, a twin engine airplane entered an uncontrolled descent during its initial climb. The aircraft lost stability and transitioned into a steep dive, eventually impacting the ocean surface a few kilometers away from the coastline.
All 17 occupants on board the aircraft perished in the accident. There were no survivors reported from the wreckage.
Findings
During the ascent phase of the flight, the aircraft became unmanageable and plummeted toward the water. The primary factor in the loss of control was the aircraft entering a dive immediately after takeoff.
