State, local and company officials weren't popping champagne corks when Boeing Co. landed a $3.69 billion commercial jet order. But they were delighted about the years of economic stability expected to stem from the sale.

"As the saying goes, `what's good for Boeing is, by and large, good for Seattle,' " laughed D'Anne Mount, spokeswoman for the city's Department of Community Development.The order Boeing announced Monday represented most of a rec-ord $5.04 billion, 130-plane purchase by International Lease Finance Corp., which leases planes to many of the world's airlines. Europe's Airbus Industrie consortium got the rest of the order.

R.R. Albrecht, executive vice president in charge of sales and marketing for Boeing Commercial Airplanes, said the order would not change production schedules.

But it will add stability and keep the world's leading airplane manufacturer working at full capacity through 1991, even if Boeing receives no other airplane orders, Al-brecht said.

Boeing employs 90,000 people in the Seattle area and directly or indirectly provides for one of every four jobs in a metropolitan area of 1.5 million people, Mount said.

But the ripple effect of Monday's 100-plane order will be felt by the whole state through the early 1990s, said Dick Milne, Gov. Booth Gardner's press secretary.

"Any time Boeing gets an order of that magnitude it's good news for the whole state," said Milne. "It may not mean a single new job, but it means that the ones we have are secure through 1995."

Monday's order easily put Boeing on a record sales pace, one that industry analysts said may quicken more as recent safety incidents prompt airlines to review their aging fleet and consider orders for new planes.
