The ATSB is investigating an in-flight engine shutdown involving Qantas Airbus A380, VH-OQG, near Los Angeles, United States, on 20 May 2017.

Passing about 32,500 ft on climb, the No. 4 engine experienced an increase in engine vibration. The flight crew shut the No. 4 engine down. The aircraft returned to Los Angeles Airport and landed without further incident.  

The aircraft (VH-OQG) was powered by Rolls Royce Trent 900 engines. A borescope inspection of the affected engine was completed on 26 May, which showed damage from Stage 2 onwards of the low pressure turbine.

An engineering team from Rolls Royce will be undertaking a controlled strip of the engine and a detailed investigation, with an estimated completion date of 16 June. The strip and further investigation will be overseen by representatives from Airbus, Qantas, the ATSB’s partner agency in France (BEA), and in communication with the ATSB’s partner agency in the UK (AAIB).

A final safety report will be released following the conclusion of the ATSB’s investigation. Should a 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.
