At 07.30 local time (lt) the aircraft lifted off the Jayapura runway and set course for the 244 miles (390 kilometer) flight to Tanah Merah. The pilot in command was the pilot flying (PF) and the co-pilot was the pilot monitoring (PM) this sector.
The weather at Tanah Merah (recorded at 09.00 lt) was calm;
Wind - 300º / 4 knots
Visibility - 8000 meters
Clouds - scattered at 210 meters // broken at 1000 meters
After an uneventful flight, the aircraft overflew the airport and joined a left downwind for runway 25 at 900 feet. The final approach speed (Vref) was The right-hand propellor and part of the determined to be 105 knots. engine gearbox (Source & © NTSC) The aircraft touched down normally at 09.17 lt in the touchdown zone of runway 25. Reverse thrust was selected to aid the deceleration of the aircraft. ~500 meters into the landing roll, at a speed of 60 knots, reduced and the condition levers were selected to minimum. Shortly afterward the aircraft, without warning, pulled to the right abruptly. The crew applied a full left rudder and left wheel brake to correct the aircraft's trajectory, but they were unsuccessful and the aircraft left the runway approximately 600 meters from the touchdown area. The right main landing gear left the paved surface of the runway and immediately sank into the soft ground, while the left main landing gear and the nose wheel remained on the hard area adjacent to the runway. Because the right main landing gear sank into the soft ground the right-hand propellor struck the ground, fracturing the blades and tearing the propellor assembly from the aircraft, coming to rest approximately 4.5 meters from the right engine, which was substantially damaged.
