Flight History
On 13 October 2016, a Cessna 208B EX aircraft registered PK-LTV, operated by PT. Asian One Air, conducted an unscheduled cargo flight from Mozes Kilangin International Airport in Timika to Ilaga Airport in Papua. The aircraft departed Timika at 0550 local time (2050 UTC) and climbed to a cruising altitude of 13,000 feet. On board were two pilots: the pilot in command acting as pilot flying and the second in command performing route familiarization. The aircraft carried 1,303 kg of cargo.
The flight proceeded northeast of Timika, passing through U Pass and Ilaga Pass before beginning descent. At about 2119 UTC, while over Ilaga Pass, the pilot contacted the Ilaga Flight Information Service Officer (FISO). The FISO reported that the weather at Ilaga was cloudy with calm wind and visibility below 1,000 meters.
The aircraft descended to 8,500 feet, and the pilot intended to join a left downwind for runway 25 at about 120 knots. During the left downwind, the pilot noted that the view of the runway was partially obscured by clouds. The approach was continued, and the aircraft turned onto left base for runway 25. While descending through 8,000 feet at about 98 knots, the pilot stated that the final direction of runway 25 became visible. The pilot then executed a left orbit on final approach to lose altitude, descending to 7,700 feet. The FISO observed that during the orbit, the aircraft was partially obscured by clouds.
At 2122 UTC, the FISO advised the pilot that visibility on final was partially blocked by clouds but that the view from the FISO room to the runway threshold was clear. As the aircraft turned onto the final approach path, the pilot reported the runway in sight and continued the landing. The aircraft's speed was approximately 90 knots with flaps fully extended.
Landing and Overrun
The aircraft touched down on runway 25 about 120 meters from the runway's beginning at an estimated speed of 85 knots. During the landing roll, the pilot applied thrust reverser and brakes. The aircraft overran the end of the runway and came to a stop on the left side of the runway's end. The propeller struck the ground. The aircraft sustained substantial damage, including a collapsed nose landing gear and bent propeller blades. No injuries were reported among the two occupants.
Pilot Information
The pilot in command was 62 years old and had joined the company in September 2016. He held a valid Airline Transport Pilot License and a first-class medical certificate valid until 31 December 2016, with a limitation requiring corrective lenses for distant vision and reading glasses for near vision. His total flying experience was 21,861.58 hours, including 2,209.58 hours on the Cessna 208B EX. In the last 90 days he had flown 124.24 hours, and his flight time in the last 24 hours was 35 minutes.
The second in command was a newly hired pilot undergoing route familiarization. He was 40 years old.
Aircraft Information
The aircraft was a Cessna 208B EX, registration PK-LTV. It was being operated as a cargo flight.
Aerodrome and Weather
Ilaga Airport (WAYL) is located in Papua. At the time of the incident, the weather was reported by the FISO as cloudy with calm wind and visibility less than 1,000 meters. The FISO also noted that visibility on the final approach area was partially blocked by clouds, while the view from the FISO room to the runway threshold was clear.
Investigation Status
At the time of the preliminary report, the Komite Nasional Keselamatan Transportasi (KNKT) had not been informed of any safety actions resulting from this occurrence. The investigation was ongoing, and the report contained only factual information without analysis or conclusions.
