Up to 40 Rolls-Royce engines on Airbus A380 superjumbos worldwide will need to be replaced, according to Australian airline Qantas.
Qantas chief executive Alan Joyce was speaking two weeks after a Rolls-Royce Trent 900 engine on an A380 exploded in mid-air, forcing an emergency landing.
Qantas has grounded its six A380s since the incident.
The Trent 900 engines are used on A380s operated by Qantas, Lufthansa and Singapore Airlines.
Between them the three airlines operate 20 A380 planes, each of which has four Rolls-Royce engines.
Mr Joyce told reporters at Sydney airport the airline had already replaced three engines on its planes.
"We've been talking to Airbus and Rolls-Royce and we understand that the number [of engines to be replaced] is around 40," he said.
"We'll have a daily dialogue with Rolls-Royce to determine which engines actually need to be taken off," he said.
