Australian air safety investigators have arrived in Singapore to examine how a Qantas passenger jet blew out an engine, punching a hole in its wing after it took off for Sydney.
The Airbus A380 was forced to turn back to make an emergency landing at Changi Airport on Thursday after the explosion which left debris strewn over the nearby Indonesian island of Batam.
Flight QF32 was carrying 433 passengers and 26 crew when part of the cover on its No 2 engine blew off about five minutes after leaving Singapore.
One passenger reported hearing a "massive bang" before the plane turned back.
Qantas said the passengers are heading home on several flights on Friday, the ABC reports.
A team of investigators from the Australian Transport Safety Bureau have sent the black box flight recorders from the plane to Australia for analysis.
Airbus, the European manufacturer of the aircraft, said it would send a team of specialists to assist the investigation.
The Qantas fleet of six Airbus A380s remains grounded, but Singapore Airlines said its fleet of 11 aircraft, the second largest in the world, has been inspected and is cleared for take-off.
Qantas chief executive Alan Joyce told news conference on Friday checks will probably show the engine failure was a material failure or some sort of design issue.
Mr Joyce said the company is talking to engine manufacturer Rolls Royce and Airbus.
Earlier, Rolls-Royce said it was in the process of checking the 20 A380 planes with with Qantas, Singapore and Lufthansa that use its Trent 900 engines.
The other 17 A380s in service - with Air France and Emirates - use another engine.
Airbus said it will provide full technical assistance to Australian and French accident investigators.
Stocks in Airbus owner, EADS, and the engine maker Rolls Royce have both fallen nearly 5%.
