History of the Flight
On 27 October 2015, a Cessna 208B Grand Caravan, registered PK-RSE, operated by PT. Enggang Air Service, was conducting a charter flight from Wamena Airport to Sinak Airport, both in Papua, Indonesia. The aircraft carried 1,178 kg of cargo. On board were two pilots: the Pilot in Command (PIC), who acted as Pilot Flying, and the Second in Command (SIC), who acted as Pilot Monitoring. This was the second flight to Sinak for both pilots.
According to the pilot report, the aircraft departed Wamena at 0002 UTC and climbed to a cruising altitude of 13,000 feet via Tiom and Mulia. While over Mulia, the aircraft began its descent. Approximately 12 nautical miles from Sinak, passing through 9,000 feet, the pilot felt a loss of engine power. The PIC briefed the SIC on engine loss power procedures.
The pilot maintained an airspeed of 95 knots and attempted to open the power lever three times, but the engine did not respond. The descent continued at a rate of 800 feet per minute.
During the final approach to runway 26, the aircraft encountered a headwind of about 13 knots, which then changed to a tailwind of about 13 knots. The pilot reported difficulty controlling the aircraft under these conditions and decided to execute an emergency landing procedure. The fuel shutoff valve was closed a few seconds before touchdown.
The aircraft touched down approximately 75 meters before the beginning of runway 26, veered to the left side, and came to a stop about 10 meters to the left of the runway start. All occupants evacuated without injuries.
Damage to Aircraft
The aircraft sustained substantial damage, including:
- Right outer wing bent upward and dented
- Left landing gear shifted backward
- Nose wheel burst
- Propeller blades bent backward
- Engine mounting strut bent
- Lower nose cowling broken
