On 11 May 2013, the pilot of a Pacific Aerospace Fletcher FU24-950 aircraft was conducting aerial agricultural spraying activities near North Rawajitu, Lampung, Indonesia, when the aircraft collided with terrain. The pilot was fatally injured and the aircraft destroyed.

The National Transportation Safety Committee (NTSC) of Indonesia is responsible for investigating this accident. The aircraft carried an Ag-Nav GPS-based guidance and track monitoring system which the NTSC downloaded using conventional techniques. The normal download yielded data prior to the accident flight. The NTSC requested specialist assistance from the Australian Transport Safety Bureau (ATSB) to recover any accident flight data from the Ag-Nav system non-volatile memory chips that may not yet have been written to the unit's normal file system.

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

Download, examination and correspondence with the unit's manufacturer yielded no additional data beyond that retrieved in Jakarta. The latest available data from the Ag-Nav unit was found to be on 10 May 2013 consequently no accident flight data was available to assist the NTSC investigation team.

A report detailing the download and data examination was provided to the NTSC on 29 October 2013.

All inquiries regarding the investigation into this accident should be forwarded to the National Transportation Safety Committee of Indonesia.
