Technical assistance to the Transport Accident Investigation Commission New Zealand investigation of a loss of control on the ground involving Boeing 777, ZK-OKN, at Auckland Airport, New Zealand on 27 January 2023

On 27 January 2023 a Boeing 777 aircraft, registered ZK-OKN, was conducting a scheduled passenger flight from Melbourne, Australia to Auckland, New Zealand. Shortly after touchdown at Auckland airport, the aircraft briefly lost directional control and the aircraft veered away from the runway centreline. There was damage reported to 6 runway edge lights and to the aircraft’s undercarriage assembly, including deflation of one tyre, there were no injuries to passengers or crew.

The Transport Accident Investigation Commission (TAIC) requested assistance from the Australian Transport Safety Bureau (ATSB) to download the aircraft’s cockpit voice recorder (CVR) and flight data recorder (FDR) to assist their investigation.

To facilitate this support and to provide the appropriate protections for the 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.

The recorders were downloaded at the ATSB Canberra facilities on 9 February 2023 and the voice and flight data from the occurrence flight were retrieved and provided to the TAIC investigators in attendance. ATSB staff assisted with further analysis of the data as required. 

The TAIC was responsible for the investigation and released the final investigation report regarding this occurrence on 29 May 2025. The report is available here.
