Sydney:
A Qantas jet with nearly 200 passengers on board was forced to make an emergency landing on Thursday at Sydney's international airport after its landing gear failed to retract following takeoff.
An airline statement on Thursday said the Airbus 330 jet bound for Shanghai was forced to circle over Sydney for more than two hours and burn off fuel, before safely making an emergency landing.
Australia's aviation safety agency in 2008 ordered Qantas to improve its maintenance system, following a review prompted by a series of safety problems, including an oxygen tank explosion on a Boeing 747-400 that ripped a hole in the jet's fuselage, forcing it to make an emergency landing in the Philippines.
No one was injured.
