A Qantas plane returned to Singapore with an engine problem shortly after take-off today, local reports said.
Channel 5 said the Boeing 747 was forced to return to Singapore soon after leaving the airport.
Channel News Asia said flight QF6 turned back after a problem with engine one. It gave no other details.
It came a day after a Qantas Airbus A380 superjumbo made an emergency landing in Singapore after one of its four engines suffered a blow-out.
Channel News Asia quoted Qantas as saying the flight, which had 431 people on board and was operating from Singapore to Sydney, “experienced an issue with its number one engine”.
Qantas added that as a precaution, the captain of the jumbo jet sought priority clearance to return to Singapore, CNA reported, and the aircraft landed safely.
It said there were 412 passengers, three flight crew and 16 cabin crew on board.
