On 31 March 2009, the pilot of a Fairchild Metro SA227-AC aircraft, registered ZK-NSS, experienced control difficulties during landing at New Plymouth Aerodrome, New Zealand, with the aircraft subsequently departing the runway. The New Zealand Transport Accident Investigation Commission (TAIC) commenced an investigation into the occurrence on 1 April 2009 (investigation number 09-003).

On 1 February 2010, the TAIC requested assistance from the Australian Transport Safety Bureau (ATSB) in the review and analysis of data recovered from the aircraft's flight data recorder (FDR). To protect the information supplied to the ATSB and the investigative analysis carried out to assist the TAIC, the ATSB initiated an investigation under the Transport Safety Investigation Act 2003 (TSI Act), and appointed an accredited representative to the TAIC investigation, in accordance with clause 5.23 of Annex 13 to the Convention on Civil Aviation (Chicago Convention).

The ATSB has completed its review and analysis of the FDR information from ZK-NSS and has provided feedback to the TAIC.

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