Qantas has begun legal proceedings against Rolls Royce after an engine on one of its fleet of A380s exploded mid-air last month.
The Australian flag-carrier wants to recoup the estimated 100 million dollar cost of grounding its six planes as a result of the November the 4th emergency.
The aircraft, with 466 people on board, landed safely in Singapore.
It comes after investigators said a manufacturing fault on an engine was to blame, causing cracking, leakage and eventually a fire.
British manufacturer Rolls Royce has introduced a system of inspection, maintenance and removal to make sure its Trent 900 engines run safely.
Only A380s belonging to Qantas, Lufthansa and Singapore Airlines use the Trent 900.
Air France and Emirates – the other airlines with super jumbos – use a different make.
