Aviation Partners Announces Record Sales.

Business Editors

SEATTLE--(BUSINESS WIRE)--Feb. 2, 2000

In a record-breaking sales month to kick off the New Year, Aviation Partners sold five shipsets of patented(a) Blended Winglet Systems during January. With close to 100 Blended Winglet Systems for the Gulfstream II sold to date ($475,000 installed in 10-12 days downtime) it won't be long before the entire GII fleet is upgraded to Performance Enhanced IISPs.

&uot;Selling this many Blended Winglet sets in one month is a landmark for our company,&uot; says Aviation Partners Vice President of Sales and Marketing Dick Friel. &uot;But, more than that, it's a testimonial to the market acceptance and the pent-up demand for this remarkable Performance Enhancing Technology.&uot;

Since Blended Winglet Technology was first introduced in 1993, IISP operators have enjoyed 7% additional range, higher initial cruise altitudes and improved performance through all phases of flight. These tremendous advantages, made possible by correctly sizing and shaping winglets for maximum drag reduction, will soon be available as standard equipment on the Boeing Business Jet. Up to 10,500 existing Boeing commercial aircraft stand to benefit from the advantages of revolutionary Blended Winglet Technology through Aviation Partners Boeing, a joint venture partnership established last year.

&uot;The technology we have works very well and it will benefit any aircraft flying today,&uot; explains Aviation Partners CEO Joe Clark. &uot;I'm gratified by the acceptance of our Blended Winglet Technology in the marketplace. Our aerospace team of top industry engineers has a full plate these days in applying Blended Winglet Performance Enhancing Technology to a range of commercial, business and regional transports. We expect a banner year in Blended Winglet sales.&uot;
