Mimika Air Flight 514

On the morning of 17 April 2009, while en route to Mulia, the aircraft impacted Mount Gergaji, killing all eleven people on board.

[2] The Indonesian National Transportation Safety Committee released a report that concluded the crash was due to the pilot's lack of familiarization with the route, coupled with spatial disorientation occurring after the aircraft entered clouds.

Pilots familiar with the route and the aircraft type reported that it was impossible for a Pilatus Porter to depart from Ilaga and climb over Mount Gergaji without making a series of circles in flight.

A validation certificate was also received by the Indonesian Directorate General of Civil Aviation (DGCA) on 12 February 2009.

Twenty-three minutes after departure, the control tower tried to make contact with the plane, but there were no response, and a search operation was commenced.

[1] The Porter had gone down about 12,000 ft (3,658 m) up Mount Gergaji, close to the site of a 2006 Trigana Air Service aircraft crash which had killed nine people.
