San Diego, USA- North America, California, May 29, 2007

Hamilton Sundstrand has delivered the first APS 5000 Auxiliary Power Unit (APU) to Boeing for the initial flight-test of the 787 Dreamliner. Hamilton Sundstrand is a subsidiary of United Technologies Corp. (NYSE: UTX). 

A delivery ceremony recently took place at the Hamilton Sundstrand Power System facility in San Diego. 

“The delivery of the first APS 5000 is a significant milestone for the 787 program,” said Dan Buchacher, Boeing's APU life cycle product team leader. “We look forward to working with the Hamilton Sundstrand team here in San Diego as we near flight testing later this year.” 

“This is a major accomplishment that couldn't have been achieved without the outstanding support of all our employees and the guidance and support of the Boeing APU team,” added Tim Morris, president of Hamilton Sundstrand Aerospace Power Systems. 

Auxiliary power units provide power to aircraft while they are on the ground, and back-up power while in-flight. The APS 5000 APU is rated at 1,100 shaft horsepower and is designed to start and function throughout the full range of the 787 operating envelope up to 43,000 feet.

In addition to the APU, Boeing chose Hamilton Sundstrand to provide the 787's environmental control system, electric power generation and start system, remote power distribution system, primary power distribution system and high-voltage DC equipment racks, emergency power system, nitrogen generation system and electric pump subsystem. 

Rolls-Royce also chose Hamilton Sundstrand to supply the gearbox system for its Trent 1000 engine being developed for the Boeing 787. And Kidde Aerospace & Defense, which recently joined Hamilton Sundstrand, is supplying Boeing with the complete fire protection systems package for the 787. The 787 program is expected to generate more than $15 billion in revenue for Hamilton Sundstrand over the life of the program.
