Investigation completed


On 9 April 2014, a Quest Aircraft Company Kodiak 100 registered PK-SDF collided with terrain during take off from Doyo Baru Airstrip, Jayapura, Papua Indonesia. The accident destroyed the aircraft and fatally injured the two occupants.

The National Transportation Safety Committee (NTSC) of Indonesia is responsible for investigating this accident. The aircraft was fitted with advanced cockpit instrumentation that included a flight data logging function. Although subjected to significant fire damage, the cockpit instrumentation and associated avionics were recovered by on site investigators and transported to the NTSC facilities for further examination. Examination of the instruments revealed remnants of non-volatile memory devices that were fitted to the cockpit displays.

The NTSC requested specialist assistance from the Australian Transport Safety Bureau (ATSB) to attempt the recovery of flight data from the non-volatile memory chips fitted to the cockpit instrumentation.

In accordance with clause 5.23 of Annex 13 to the Convention on International Civil Aviation (ICAO Annex 13) the ATSB appointed an Accredited Representative to assist the NTSC and initiated an investigation under the Australian Transport Safety Investigation Act 2003.

Examination of the instrument display components indicated they had suffered significant heat exposure resulting in the memory device packaging melting. The examination revealed parts of the memory device were present in the display components, however the memory chip could not be located. Consequently no accident flight data could be recovered to assist the NTSC investigation team. Preliminary results were conveyed to the Head of Aviation Sub Committee and a final report provided in November 2014.

The National Transportation Safety Committee of Indonesia is responsible for releasing a final investigation report regarding this occurrence. Contact details for the NTSC are:
