"This has nothing to do with the oil leaks detected in engines of Qantas and Singapore Airlines," he said, adding that the move would not result in any delays.

Australian carrier Qantas was forced to ground its entire Airbus fleet after a mid-air engine blowout on one of the planes nearly a week ago.
