Aircell Axxess Selected by Gulfstream as Factory-standard Cabin Communications System September 24, 2007 ATLANTA, GA [NBAA Annual Meeting & Convention] – September 24, 2007 – Aircell is pleased to announce that Gulfstream Aerospace has selected the Aircell Axxess™ cabin communications system as standard factory equipment aboard the entire family of Gulfstream large-cabin business jets. The announcement comes during a period of extraordinary growth at Aircell, and adds to the more than two dozen factory aircraft programs where Aircell equipment is offered as standard or optional equipment. The program continues a burgeoning business relationship between the two companies, which began in October of last year when Gulfstream selected the Aircell Axxess EZ system as its aftermarket MagnaStar ® -replacement. Gulfstream continues to offer that system on a retrofit basis through its network of U.S. service centers and third-party authorized facilities. Jack Blumenstein, Aircell President & CEO, said, “We’re proud to extend our partnership with Gulfstream to the production line of their large-cabin jets. Having another Aircell system selected by one of the world’s most respected aircraft manufacturers is a wonderful affirmation of the leadership position we’ve earned over the years.” Aircell will begin shipping production Aircell Axxess systems to Gulfstream later this year, to be installed in large cabin aircraft delivering in the second quarter of 2008.
