What happened
During an approach to Tarakan-Juwata Airport, the flight crew received notification that visibility was significantly reduced due to smoke originating from a local forest fire. Upon landing on runway 06/24, which has a length of 1,845 metres, the aircraft lost control. The plane subsequently veered off the prepared surface, resulting in the loss of one engine and the separation of the undercarriage. The aircraft sustained damage that rendered it a total loss.
Despite the severity of the excursion, all 110 occupants managed to evacuate the aircraft without any uninjured injuries reported.
Findings
At the time of the incident, visibility was measured at approximately 400 metres, which was below the required minimums for safe operations. The presence of smoke from forest fires was the primary factor impacting the visual conditions during the landing phase.
