ANALYSIS-Boeing 787 output, review threatened if engineers strike

(Changes dateline. Adds Boeing response to union offer, FAA

grounding of 787s and Boeing response in paragraphs 6-8.)

SEATTLE, Jan 16 (Reuters) - An escalating series of mishaps

on Boeing's new 787 Dreamliner has dealt engineers pushing for a

new contract a strong card to play at the negotiating table.

The engineers are considered by aviation experts to be

crucial to a safety review of the 787 that the Federal Aviation

Administration launched last week after a fire, fuel leaks and

other failures sparked widespread fears about the new jet.

The safety concerns threatened to turn into a full-blown

crisis for Boeing on Wednesday when Japan's two leading airlines

grounded their 24 Dreamliner passenger jets when one of the

aircraft made an emergency landing after instruments indicated a

battery error and smoke. The Japanese aircraft

account for nearly half the 50 Dreamliners now flying.

On Wednesday, the union made a "best and final" offer to

Boeing, proposing to incorporate areas where the two sides had

already agreed into the expired contract and extend it for four

more years.

This would end "protracted and increasingly contentious

negotiations that appear headed for a strike," the union said,

and allow Boeing and its workers "to focus on reaffirming

confidence and proving the 787 is the reliable and safe product

employees know it to be."

Boeing said it was reviewing the offer and talks would

continue Thursday.

The news came as the FAA required airlines to stop flying

787s, and Boeing CEO Jim McNerney said the

company would use all of its resources to find answers to the

problem qu ickly. [ IDA:L1E9CH0EY]

The FAA action, and its review , come after an extraordinary

string of mishaps, including a battery fire, two fuel leaks,

three electrical faults, a cracked cockpit windscreen, an engine

oil leak and brake problems that have raised safety concerns

with the new carbon-plastic composite aircraft.

Experts said a walkout by engineers would impede both the

safety review and Boeing's ambitious effort to double production

of the 787 this year because key people with knowledge of the

aircraft and the clearance to certify that production lines are

meeting FAA requirements would be taken away.

"The engineers have to be involved," said R. John Hansman, a

professor of aeronautics and astronautics at Massachusetts

Institute of Technology. "Nobody at the FAA knows this airplane

as well as the engineers who were involved in the design and

testing."

STRIKE WOULD SLOW REVIEW

Boeing has said it has engineers in California and elsewhere

who can work on planes if the union-represented engineers walk

out. Some Boeing managers also have the necessary high-level

clearance to certify aircraft, according to officials at the

union and industry experts.

However, before it could use replacement engineers either

for production or the review, Boeing would need to convince the

Federal Aviation Administration that those workers have the same

skills as the union members, Boeing and the FAA said.

Obtaining FAA approval would slow the safety review, which

is already expected to take months.

"Under the rules, Boeing would need to submit a plan to the

FAA to show that any replacement workers brought in to work on

certification issues would be as capable as those they replaced,

and the FAA would need to approve it, for the 787 review to go

on," an FAA spokesperson said.

"Anytime any company has labor issues or is in bankruptcy,

we would normally heighten surveillance of the compliance" with

FAA certification rules.

Boeing declined to comment further on how it would handle

the review or production during a strike, although industry

experts said it might have more people in reserve who have the

high-level FAA authorization to conduct the review or work on

planes.

"We don't generally talk publicly about contingency for a

strike because we are focused on getting an agreement," Boeing

spokesman Doug Alder said.

For its part, the union says the safety review needs to

include engineers who oversaw the original plane certification,

or the review will not be credible.

"I don't see how you could do that review without having the

key people present to participate," said Ray Goforth, executive

director of the Society of Professional Engineering Employees in

Aerospace, or SPEEA.

PLANE PRODUCTION MIGHT CONTINUE

Boeing may still produce aircraft if the engineers walk out.

During a 40-day SPEEA strike in 2000, Boeing produced 19 planes,

according to union records.

Boeing made clear last Friday that it could call on

contingent workers from its wider operations, which include not

just airplanes, but defense, space and security businesses.

"We are the Boeing company and I have access to significant

resources across the entire corporation," Mike Delaney, a vice

president of engineering and a member of Boeing's labor

negotiating team, said during a news conference call.

There also is potential for the two sides to strike a deal.

Boeing made a contract offer on Friday that improved raises

for the engineers to between 4 percent and 5 percent a year from

3 percent to 4.5 percent.

But SPEEA said it views the latest offer as making

across-the-board pay and benefit cuts at "a time when Boeing is

posting record profits and lavishing pay raises and bonuses upon

its executives."

The FAA told Reuters it has started to work with Boeing to

assemble teams for the safety review. The teams ordinarily would

include the relatively few union-represented engineers with

high-level FAA authorization to certify the plane is in

compliance with FAA safety rules, the FAA said.

If those people are on strike, then the review could not

call on those most familiar with the design and manufacturing of

the plane. The team likely would draw on some replacement

workers, who would need to be approved by the FAA, the FAA said.

Hansman, the MIT professor, who also serves on an FAA

advisory committee, said replacement workers who have not dealt

with the 787 before could turn to technical records and

drawings.

"But that will take them a lot more time," he added.

SERIES OF FAULTS

The FAA, Boeing and SPEEA say the 787 is safe to fly and

that minor problems are common when new types of jets first

start operating. Airlines and analysts also back that view.

The National Transportation Safety Board has launched a

separate investigation into the battery fire that occurred on a

Japan Airlines jet in Boston.

The NTSB said on Wednesday it is sending a person to Japan

to investigate the smoke and battery issues that grounded the

fleets there.

The other incidents are considered normal by aviation

experts, but their quick succession on relatively few planes has

drawn attention to the problems.

Boeing stock closed down 3.4 percent at $74.34 on Wednesday.
