Boeing Co. and All Nippon Airways are investigating a potential glitch with Boeing's new 787 Dreamliner after the landing gear failed to deploy properly on one plane.

British Airways and Rolls-Royce said Thursday that they have completed contracts for Trent 900 engines to power a dozen Airbus A380s, the first announcement of any deal for the giant engines since one disintegrated in flight on a Qantas superjumbo in November.

Australia's Qantas airline hopes to resume its A380 flights to Los Angeles by mid-January, more than two months after an engine blowout forced the carrier to temporarily ground its superjumbo fleet.

The global aircraft industry will recover faster than expected, according to European manufacturer Airbus, which on Monday predicted about $3.2 trillion in new passenger and freighter planes will be needed over the next 20 years.

Australian officials investigating the mid-air disintegration of an engine on a Qantas superjumbo said Thursday they identified a potential manufacturing defect in Rolls-Royce engines used in 20 A380s worldwide that could cause engine failure.

A Qantas A380 carrying more than 450 passengers, including the airline's chief executive, took to the skies Saturday in the first flight by one of its superjumbos since a midair engine explosion three weeks ago triggered a global safety review.

Rolls-Royce modified a problematic section on new models of its engine for the world's largest jetliner months before one caught fire and blew apart over Indonesia, a Lufthansa spokesman said Thursday.

Up to half of the Rolls-Royce engines of the type that disintegrated on an Airbus superjumbo this month may need to be replaced by the three carriers in Australia, Singapore and Germany that use them, the Qantas chief executive said Thursday.

Silence has not proved golden for Rolls-Royce, the maker of an engine that blew apart on the world's biggest commercial jetliner this month, shooting metal scrap into the wing and setting off a plunge in the British company's stock price.

Rolls-Royce will temporarily replace entire engines suffering from oil leaks on the world's largest jetliner, an aviation regulator told The Associated Press on Monday.

Australia's national airline is keeping its flagship superjumbos on the ground more than a week after a frightening midair engine disintegration, disrupting its most lucrative long-haul routes even as regulators and pilots say the Rolls-Royce motors are safe.

Airbus' parent company EADS NV reported a narrow third-quarter profit on Friday, rebounding from a loss a year earlier as its plane-making business continued to improve in line with the global economic recovery.
