Preliminary report release: 8 November 2012
The ATSB has released its preliminary factual report into the collision with terrain that occurred 36 km south-west of Gympie, Queensland on 1 October 2012. The information contained in the report is derived from the initial investigation of the occurrence. Readers are cautioned that new evidence will become available as the investigation progresses that may alter the circumstances as depicted in the preliminary report. As such, no analysis or findings are included in the report.
At about 1107 Eastern Standard Time on 1 October 2012, a de Havilland Aircraft Pty Ltd DH-84 Dragon, registered VH-UXG, took off from Monto on a private flight to Caboolture, Queensland under the visual flight rules. At 1315, the pilot contacted Brisbane Radar air traffic control (ATC) and advised that the aircraft’s position was about 37 NM (69 km) north of Caboolture and requested navigation assistance. At 1318, the pilot advised ATC that the aircraft was in ‘full cloud’.
For most of the remainder of the flight, the pilot and ATC exchanged communications, at times relayed through a commercial flight and a rescue flight in the area due to the limited ATC radio coverage in the area at low altitude. At 1348, the pilot advised Air Traffic Control that the aircraft had about an hour’s endurance remaining. The pilot’s last recorded transmission was at 1404.
A search for the aircraft was coordinated by Australian Search and Rescue (AusSAR). The aircraft wreckage was located on 3 October 2012, about 87 km north-west of Caboolture.
The aircraft was destroyed by impact forces. There was no fire. The accident was not survivable and the six occupants were fatally injured.
The ATSB's investigation is continuing and will include examination of the:
- relevant air traffic radar and radio recordings
- weather information pertinent to the flight
- witness reports
- aircraft’s maintenance records
- pilot’s records and history, and
- search and rescue records.
It is anticipated that the investigation will be completed by October 2013.

History
Update: 9 October 2012
ATSB investigators have worked alongside Queensland police sifting through the aircraft wreckage and examining the accident site in detail. Although the site was somewhat difficult to access, and the extent of the damage to the aircraft made conditions difficult, the investigators have now finished the on-site phase of the investigation and will shortly commence drafting a preliminary factual report. The ATSB aims to release this report to the public within 30 days of the accident.
Despite the on-site challenges, the ATSB investigators:
- surveyed the site in detail
- interviewed a number of witnesses who saw the aircraft prior to the accident
- retrieved a Global Positioning System unit circuit board from the wreckage, although impact damage to the board may preclude the recovery of any data
- retained several aircraft items and components for further examination including:
- both engines and propellers
- a number of aircraft instruments
- several electrical and communications devices from which relevant data may be able to be recovered.
As part of the ongoing investigation, investigators will examine the:
- relevant air traffic radar and radio recordings
- weather information pertinent to the flight
- witness reports
- aircraft’s maintenance records
- pilot’s records and history.
Update: 3 October 2012
The ATSB is investigating an accident involving a DH 84 Dragon aircraft that was reported missing in Queensland on 1 October 2012.
The aircraft departed Monto that day with six persons on board. The pilot later reported entering cloud and requested assistance from air traffic control to exit those conditions. Communication with the aircraft was subsequently lost.
A search for the aircraft was coordinated by Australian Search and Rescue (AusSAR). The aircraft wreckage was located south-west of Gympie on 3 October 2012.
The ATSB has dispatched a team of four investigators to begin the on-site phase of the investigation. The team comprises experts in aircraft operations, aircraft maintenance and flight systems.
Investigators will be:
- examining the wreckage and surrounds for evidence
- interviewing witnesses and others involved in the aircraft’s operation
- obtaining the available recorded information, such as radio and radar data
- examining documentation relating to the aircraft’s maintenance history.
If you have any information about the accident please call the ATSB on 1800 020 616.
The ATSB aims to finalise its investigation within 12 months.
