Singapore Airlines has grounded three of its A380 fleet after detecting issues with Rolls Royce engines fitted on the craft.
The carrier will change the engines in the three planes, which an airline spokeswoman said were on the ground in Melbourne, Sydney and London.
Singapore Airlines says the measures are "precautionary changes" following a mid-air engine failure on Qantas-operated superjumbo last week.
Reuters reported that the replacement model of engine will remain the same - a Trent 900 - but they will receive minor modifications.
"Based on further analysis of inspection findings as the investigation into last week's incident involving another operator's Airbus A380 is progressing, Singapore Airlines will be carrying out precautionary engine changes on three A380s," the carrier said in a statement.
Singapore Airlines said passengers flying from Melbourne to Singapore were delayed for a few hours on Wednesday morning before being accommodated on an alternative aircraft.
It warned that passengers due to leave Sydney for Singapore on Wednesday afternoon may face disruptions as the airline seeks to accommodate them on other flights.
"We are assessing the best options for passengers making connecting flights from Singapore and looking to minimise passenger disruption," the airline spokeswoman said.
"We apologise to our customers for flight disruptions that may result and we seek their understanding."
