The flight crew of an Airbus A330 were alerted to a low-pressure warning from one of the aircraft's hydraulic systems. A post-flight maintenance inspection of the aircraft identified that a braided hose from an actuator to the right main landing gear door had developed a substantial leak. The Civil Aviation Safety Authority (CASA) requested assistance from the ATSB to complete a technical examination of the braided hose.
To facilitate this work, the ATSB has initiated an external investigation under the provisions of the Transport Safety Investigation Act 2003.
The ATSB has concluded the examination of the hose and provided the results of that work to CASA on 11 May 2025.
The Civil Aviation Safety Authority is responsible for and will administer the release of any information from the maintenance inspection. Any enquires relating to the matter should be directed to CASA at casa.gov.au.
