The ATSB is investigating a hydraulic system failure involving a Boeing 757, VH-TCA, Auckland International Airport, New Zealand, on 5 February 2018.

While passing 6,000 ft on climb from Auckland Airport, the flight crew received a left hydraulic system warning. After they actioned the appropriate checklist, the right hydraulic system also failed. The flight crew elected to return to Auckland, and the aircraft landed without further incident.

As part of the investigation, the ATSB will interview the flight crew, obtain engineering reports, review recorded data, and gather additional information.

A final report will be released at the end of the investigation.

Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
