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 in Singapore 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.
Qantas Boeing 747-400’s are usually equipped with 4 Rolls-Royce RB211-524G-T engines of the type which suffered an in-flight failure in August this year.
