Runway Excursion, Yayasan Pelayanan Penerbangan Tariku (Pac 750 XL Pk-Tet), Duma Airstrip (Wabe), Papua, Indonesia, KNKT.23.05.09.04

On 31 May 2023, a PAC 750 XSTOL aircraft registered PK-TET, operated by Yayasan Pelayanan Penerbangan Tariku (YPPT), was involved in an accident during a non-scheduled cargo flight from Mozes Kilangin Airport, Timika, to Duma Airstrip, Dumadama. The aircraft, carrying building materials, departed Timika at 0644 LT under improved weather conditions. As the aircraft approached Dumadama, the pilot initiated a landing on runway 08 but extended the touchdown due to muddy conditions. 

During the landing, the left main landing gear struck a boar crossing the runway, causing the aircraft to veer off and sustain substantial damage, including the collapse and detachment of the left main landing gear. The pilot, the sole occupant, was uninjured and safely evacuated the aircraft. The investigation by KNKT identified that the airstrip’s inadequate fencing allowed animals to enter the runway area, contributing to the accident.

This report outlines the factual information, analysis, conclusions, and safety actions taken following the occurrence. The KNKT’s findings emphasize the need for improved airstrip management and the installation of effective barriers to prevent similar occurrence.

The KNKT acknowledged the corrective actions undertaken by YPPT based on the KNKT’s recommendations. YPPT conducted outreach to the villagers in Dumadama, who committed to maintaining and preserving the Dumadama. The villagers also built fences around the airstrip to control and prevent wild animals from entering the area. These actions were deemed relevant for improving safety.
