Sydney , Australia ( CNN ) -- Qantas is considering legal action against engine-maker Rolls-Royce after one of the manufacturer 's engines sparked a fire on a flight last month , the airline said Thursday . The Federal Court of Australia granted the Australian carrier an injunction Thursday allowing it to pursue legal action against Rolls-Royce in Australia if a commercial settlement is not possible , Qantas said . Qantas said it has already started discussions with Rolls-Royce . A Sydney , Australia-bound Qantas Airbus A380 was forced to turn back to Singapore on Nov. 4 when an oil fire badly damaged one of the plane 's four Rolls-Royce Trent 900 engines . The fire resulted in part of the engine casing falling off in flight . The Australian Transport Safety Bureau issued a safety recommendation Thursday about the Trent 900 engines , which are installed on some A380 superjumbos , the world 's largest airliner . The ATSB said it had identified a potential manufacturing defect with the Trent 900 on some A380s that could have been a factor in last month 's fire on the Qantas flight . `` The problem relates to the potential for misaligned oil pipe counter-boring , which could lead to fatigue cracking , oil leakage , and potential engine failure from an oil fire within the HP/IP bearing buffer space , '' the ATSB said in a statement . Rolls-Royce said checks conducted immediately after the Nov. 4 incident showed the problem was specific to the Trent 900 and that it was confined to a specific component in the turbine area of the engine . That in turn caused an oil fire , Rolls-Royce said . A Rolls-Royce spokesman said Thursday the ATSB recommendation was consistent with those findings . `` We have instituted a regime of inspection , maintenance , and removal which has assured safe operation , '' the spokesman said . `` This program has been agreed in collaboration with Airbus , our airline customers , and the regulators . '' Qantas grounded its A380 fleet for several weeks while it inspected the problem . It said Thursday it is doing further one-off inspections of the engines for possible tubing defects . The ATSB plans to hold a media briefing Friday when it releases its preliminary report into the mishap . CNN 's Melissa Gray contributed to this report .
