The American
aerospace giant Boeing halted deliveries of its 787 Dreamliner on Friday but
said it would continue to build the aircraft while safety experts examine its
battery and electrical systems.
The
announcement capped a week in which all 50 787s in service around the world
were grounded on orders from multiple aviation authorities to investigate the
cause of two incidents, including a fire, linked to its batteries.
"We
will not deliver 787s until the FAA approves a means of compliance with their
recent Airworthiness Directive concerning batteries and the approved approach
has been implemented," a Boeing spokesman said.
"Production
of 787s continues," he said.

Dreamliners
had been flying in Chile, Ethiopia, India, Japan, Poland, Qatar and the United
States until their flights were stopped after a global alert issued by the US
Federal Aviation Administration.
Boeing's
chairman and chief executive Jim McNerney in a statement to employees defended
his company and the aircraft against "the negative news attention over the
past several days."
"As
everyone inside the company knows, nothing is more important to us than the
safety of the passengers, pilots and crew members who fly aboard Boeing commercial
and military aircraft," he said.
"We
have high confidence in the safety of the 787 and stand squarely behind its
integrity as the newest addition to our product family."
His
comments came as US and Japanese experts began examining an All Nippon Airways
787 forced to make an emergency landing at Takamatsu in southwest Japan on
Wednesday because of a smoke alert apparently linked to a lithium-ion battery,
the plane's main electrical power unit.
However,
reports today said the fire was not caused by an overcharged battery.
The risk
of fire from overheating powerpacks emerged as a major concern for Boeing's
cutting-edge new planes after pilots were forced to land a domestic Japanese
flight due to smoke apparently linked to the lithium-ion battery.
But the
National Transportation Safety Board (NTSB) said its examination so far has
shown the battery was not the culprit of an earlier January 7 fire on an empty
Japan Airlines plane in Boston.
''Examination
of the flight recorder data from the JAL B-787 airplane indicate that the APU
battery did not exceed its designed voltage of 32 volts,'' a statement said.
The
physical examination of the battery, including X-rays and scans of the
assembled battery and of its disassembled components, was still ongoing, the
agency said.
The NTSB
said representatives from its Japanese and French counterparts were
participating in the investigation, and noted it had sent its own investigator
to Japan for the investigation of the incident there.
No
airline has cancelled purchases for the 787, but with 850 of the ambitious
$US200 million-plus ($A190 million) aircraft on order, a fortune is at stake.
The
problems have cast a cloud over the aircraft heavily dependent on pioneering
electrical systems and lightweight composite materials that is meant to be
Boeing's future.

$US200 million-plus ($A190 million) aircraft on order, a fortune is at stake.
McNerney
stressed that since they entered service in October 2011, 787s have completed
18,000 flights and 50,000 flight hours with no serious problems.
But US
Secretary of Transportation Ray LaHood told NBC television that the 787 would
have to prove itself again to US inspectors.
"Those
planes won't fly until we're 1,000 percent sure they are safe to fly,"
said LaHood on Friday.
The
focus of investigators was on batteries supplied to Boeing by Japan's GS Yuasa
through France's Thales, two of many firms in a complex global chain of
suppliers for the 787 program.
Loren
Thompson, an aviation analyst at the Lexington Institute, said Boeing was under
heavy pressure "to find a solution as soon as possible," or else it
will stop receiving payments for the aircraft on order.
"It's
a question of weeks, not months," he said.
Boeing's
engineers union, representing 23,000 staff, raised the stakes in the case on
Friday as its representatives rejected the company's "final" contract
offer and blamed the 787 problems on the manufacturer's outsourcing strategy.
The
union members will likely vote next week on whether they agree to reject the
contract offer, and that ballot could include a vote on whether to go on
strike.
"Boeing
corporate created the 787 problems by ignoring the warnings of the Boeing
technical community," said Joel Funfar, one of the union negotiators.
"Now,
they propose to double down on their failed outsourcing strategy by outsourcing
the engineering work required to solve the problems caused by previous rounds
of outsourcing."
