A Qantas airline jumbo jet has been forced to return to Singapore because of an engine problem.
The Boeing 747-400 turned back shortly after take-off from Changi Airport, airline officials said.
It comes a day after a Qantas Airbus A380 was forced to make an emergency landing at the same airport after one of its engines exploded.
Qantas grounded its six-strong fleet of A380s and an investigation is under way into what caused the failure.
The latest incident affected Sydney-bound flight QF6, which managed to land safely.
"Shortly after take-off the captain experienced an issue with one of its engines," a Qantas spokeswoman said.
No further details were immediately available.
Earlier, Qantas said the engine failure on its flagship A380 may have been caused by a design fault.
CEO Alan Joyce said the blowout was "an engine issue" and not one of maintenance on the two-year-old plane.
Rolls-Royce, the British firm which makes the Trent 900 engine involved, said it was checking all the A380s in service.
One of the plane's four engines blew up over western Indonesia, sending debris falling on to the island of Batam and leaving a trail of smoke.
