Incident Overview
On 31 May 2013, a BAe ATP freighter registered PK-DGI, operated by PT. Deraya, was conducting a scheduled cargo flight from Sentani Airport (WAJJ) to Wamena Airport (WAJW) in Papua. The flight crew consisted of a Pilot in Command (PIC) acting as Pilot Flying (PF) and a Second in Command (SIC) acting as Pilot Monitoring (PM).
Flight Details
The aircraft departed Sentani at 2127 UTC (0627 local time) and cruised at 12,000 feet (FL120). The estimated time of arrival at Wamena was 2207 UTC (0707 local time). At 2201 UTC, the pilot contacted Wamena Tower controller while approaching Pass Valley. The controller advised that runway 15 was expected to be used and reported weather conditions: wind calm, visibility 4 kilometers, low cloud at the final area, and QNH 1008 mbar. The PIC did not give a specific approach and landing briefing to the SIC considering the weather conditions.
Landing and Runway Excursion
At 2207 UTC, the pilot reported being on final approach for runway 15. The controller requested the flight condition, and the pilot stated that the runway was not in sight. At 2209 UTC, the pilot reported the runway was in sight, and the controller issued a landing clearance. Twenty-five seconds later, the aircraft touched down on the centerline. During the landing roll, approximately 750 meters from the beginning of runway 15, the aircraft veered to the left onto the runway shoulder. The pilot attempted to recover by applying right rudder and asymmetric reverse thrust, but the aircraft continued veering left and came to a stop about 10 meters onto the left shoulder of runway 15. The flight data recorder (FDR) showed that the left engine torque was greater than the right engine torque during the landing roll.
Damage and Aftermath
After coming to a stop, the pilot shut down both engines and evacuated the aircraft safely. No injuries occurred in this occurrence. The nose landing gear detached and was found on the shoulder approximately 250 meters from the aircraft's final position. The main landing gears were broken, and all propellers were bent.
