Flight History
On 10 March 2021, a Cessna 208B aircraft, registered PK-MAD, operated by Yayasan Mission Aviation Fellowship (MAF) Indonesia, was conducting an unscheduled cargo flight from Wamena Airport (WAVV), Wamena, Papua to Angguruk Airstrip, Papua. The flight was filed under Visual Flight Rules (VFR). At 0008 UTC (0908 local time), during daylight conditions, the aircraft departed Wamena. The pilot was the sole occupant and this was the second flight of the day for both the pilot and the aircraft. No aircraft system malfunctions were recorded or reported prior to departure.
Due to weather conditions and to avoid clouds, the pilot climbed to a higher altitude and flew manually without the autopilot. The aircraft's Global Positioning System (GPS) recorded passing 14,000 feet above mean sea level (AMSL) at 0928 LT. The pilot used the supplementary oxygen system before passing 14,000 feet, continued climbing to 14,900 feet, then gradually descended. At 0936 UTC, the GPS recorded descent through 14,000 feet and the pilot stopped using supplemental oxygen.
Considering the aircraft was higher than normal for the landing approach to Runway 09 at Angguruk and to avoid clouds, the pilot performed several maneuvers over Angguruk. During these maneuvers, the pilot observed that the grass on the runway, approximately 50 meters from the beginning of Runway 09 and also about 30 meters before the threshold, had a brighter color than the surrounding grass. The pilot interpreted this as cut grass.
On final approach to Runway 09, the pilot noted that the runway threshold markers were visible but less contrast due to the brighter grass. The area about 30 meters before the threshold appeared usable for landing. The pilot intended to touch down at the very beginning of Runway 09 to minimize braking.
The aircraft touched down approximately 22 meters before the runway threshold, veered left, and came to a stop about 112 meters from the beginning of Runway 09 on a heading of 182 degrees.
Injuries and Damage
No injuries occurred in this occurrence. The aircraft sustained substantial damage.
