The Australian Transport Safety Bureau (ATSB) has completed its download and replay of the cockpit voice recorder (CVR) from a Bombardier DHC-8-311 aircraft, registered ZK-NEQ. The work was conducted on behalf of the Transport Accident Investigation Commission (TAIC) of New Zealand, in support of their investigation into the failure of the aircraft's nose landing gear, and subsequent diversion to Woodbourne Aerodrome, New Zealand, on 09 February 2011.

The TAIC is responsible for investigating this occurrence and requested assistance from the ATSB to download and replay the CVR. To facilitate the ATSB's involvement, an accredited representative was appointed to the investigation, in accordance with clause 5.23 of Annex 13 to the Convention on International Civil Aviation.

To protect the CVR audio and other information supplied by the TAIC, the ATSB initiated an investigation under the Transport Safety Investigation Act 2003. The CVR was downloaded at the ATSB's technical facilities in Canberra and a copy of the recovered audio was provided to the TAIC on 16 February 2011. A download and replay of a CVR fitted to ZK-NEZ was also carried out at the ATSB on 16 Mar 2011 to assist the investigation.

The TAIC is responsible for releasing a final investigation report regarding this occurrence.
