Summary

On 5 May 2013, a Eurocopter AS365N2 helicopter, registered 9M-DBH, was involved in an accident while taxying to park at RMAF Sempang, Malaysia.

An investigation into the circumstances of the accident is being conducted by the Office of the Chief Inspector of Air Accidents, Ministry of Transport, Malaysia. The investigation is being conducted in accordance with Malaysia’s obligations as the State of Occurrence under Annex 13 to the Convention on International Civil Aviation (ICAO Annex 13) and the Malaysian Civil Aviation Regulations 1996.

The Office of the Chief Inspector of Air Accidents requested assistance from the Australian Transport Safety Bureau (ATSB) in the analysis of signals recorded on the helicopter’s cockpit voice recorder (CVR). To facilitate this support and provide the appropriate protections for the CVR information, the ATSB appointed an accredited representative in accordance with paragraph 5.23 of ICAO Annex 13 and commenced an investigation under the Australian Transport Safety Investigation Act 2003.

Download of the CVR was undertaken by the Singapore Air Accident Investigation Bureau (AAIB) and three 30-minute tracks of digital audio information were provided to the ATSB via secure file transfer. Spectral analysis of the audio was undertaken and the observations of interest compiled into a report that was provided to the Office of the Chief Inspector of Air Accidents in September 2013.

The Malaysian Office of the Chief Inspector of Air Accidents is responsible for releasing a final investigation report regarding this occurrence.
