Factual Information
On 14 November 2013, a Cessna C208B aircraft, registration PK-RSP, was operated by PT. Enggang Air Service on an unscheduled passenger flight from Sentani Airport to Nalca Airstrip, Papua. The flight was conducted under Visual Flight Rules (VFR). The aircraft departed Sentani at 2206 UTC (0706 LT) with an estimated flight time of 50 minutes and a cruise altitude of 10,000 feet. The pilot, who held a current ATP License and C208 type rating, had accumulated 16,961 total flight hours, including 1,568 hours on type. This was his first flight from Sentani to Nalca Airstrip. On board were one pilot and nine passengers.
Aircraft and Flight Details
The aircraft, serial number 2254, had 556 hours and 32 minutes total time since new with 607 cycles. It was equipped with a Pratt & Whitney PT6A-114A engine (serial PCE-PC1789) and a McCauley propeller. The actual takeoff weight was 8,977 lbs, and landing weight 8,727 lbs. Weather en route and over Nalca was fine with calm winds. No abnormalities were recorded during the flight.
Sequence of Events
The pilot descended approximately 26 nautical miles from Nalca and flew overhead to observe the airstrip. The runway was clear. He joined the downwind for runway 24 and configured the aircraft with full flaps on final approach. At 22:56 UTC (07:56 LT), the aircraft touched down on runway 24 at a landing speed of about 78 knots, slightly right of the centerline. The rollout was normal until approximately 20 meters before the parking area on the right side of the runway, where the right main wheel became trapped in the ground. The aircraft stopped with the right wing slightly down and the right wheel concealed about one meter into the runway surface.
After stopping, the pilot shut down the engine using normal procedures and assisted passengers in disembarking from the left side. No persons were injured. The aircraft was evacuated from the runway and moved to a clear area west of the airstrip.
Damage
Inspection revealed damage to the propeller blades (bent), nose landing gear misalignment, a shifted engine cowling bottom, and a bent left engine mount. Local villagers reported rainfall the day before the occurrence; no information about the airstrip condition was provided to the pilot.
Conclusions
The investigation concluded that the absence of airstrip information had made the pilot unaware of the runway surface condition, which was attributed to improper risk management in identifying, analyzing, assessing, and controlling risks.
