Quantas officials said they initiated the action against engine supplier Rolls-Royce as a backup in case it can't reach a settlement with the company over the explosion of one of its engines in flight last month, the BBC reported.
The pilots in the November flight made a successful emergency landing in Singapore after one of the explosion.
The Australian Safety Bureau found a manufacturing problem with the Rolls-Royce Trent 900 engines.
"This condition could lead to an elevated risk of fatigue crack initiation and growth, oil leakage and potential catastrophic engine failure from a resulting oil fire," the ATSB said.
Not all A380s use the Rolls-Royce Trent 900 engines, but they are used on 20 planes owned by Qantas, Lufthansa and Singapore Airlines.
Rolls-Royce said it is addressing the problem and has "instituted a regime of inspection, maintenance and removal which has assured safe operation.
The Airbus A380 is the world's largest passenger jet and can carry as many as 800 passengers.
