On 5 February 2018, at about 0652 Universal Coordinated Time (UTC), a Boeing 757 freighter aircraft, registered VH-TCA, operated by Tasman Cargo Airlines Pty. Ltd., departed from Auckland International Airport, New Zealand for Sydney International Airport, Australia.
Passing through an altitude of 6,000 ft, the flight crew received a left hydraulic quantity warning message. The crew actioned the Quick Reference Handbook (QRH) checklist and obtained clearance from Air Traffic control (ATC) to level out at 8,000 ft, in a holding pattern to the north‑west of Auckland Airport.
Shortly after entering the holding pattern, the left hydraulic system lost pressure as the hydraulic fluid quantity reduced to zero. The crew received a left hydraulic system pressure warning and followed the QRH checklist, which required switching off the left hydraulic engine driven pump and electric pump.
A few minutes later, the crew received a right hydraulic system, engine driven pump overheat message. In response, the crew actioned the QRH and turned off the right engine driven pump. Shortly after, the crew received a right-hand system pressure warning. The crew actioned the corresponding QRH checklist and shut down the right electric motor driven hydraulic pump, resulting in a loss of both the left and right hydraulic systems.
At about 0710, the flight crew declared a PAN and requested both an immediate return to Auckland and for emergency services to be put on standby. The crew received clearance from ATC to commence their approach to runway 23L. The flight crew extended the flaps and landing gear using the alternative systems, and the aircraft touched down at approximately 0735. The flight crew brought the aircraft to a halt at the anticipated location using the manual braking system.
There was no damage to the aircraft and no injuries sustained as a result of the occurrence.
After the occurrence, the operator conducted an examination of the aircraft and discovered that the left main landing gear (MLG) downlock actuator retract flexible (flex) hose was ruptured. No faults were detected during an operational check of the right system and the power transfer unit (PTU). The required components were replaced as per the aircraft maintenance manual (AMM) and the aircraft was returned to service.
