Hamilton Sundstrand Auxiliary Power Unit for Boeing 787 Program Undergoes Successful Testing

    WINDSOR LOCKS, Conn., March 5 /PRNewswire/ -- The Hamilton Sundstrand
 APS 5000 auxiliary power unit (APU) for the Boeing 787 Dreamliner is
 undergoing successful cold-weather testing in Fairbanks, Alaska. Hamilton
 Sundstrand is a subsidiary of United Technologies Corp. (NYSE:   UTX).
     Federal aviation regulations and Boeing require the APU to complete
 certification testing for cold-weather starts, operation during heavy snow
 and freezing rain, and exposure to de-icing procedures. Testing in
 Fairbanks began last November and the APS 5000 APU tailcone section has
 performed very well.
     "All of us at Hamilton Sundstrand are working extremely hard to meet
 all the requirements of the 787 program," said Geoff Hunt, Hamilton
 Sundstrand's 787 program director. "We look forward to delivering more
 hardware and seeing the 787 fly for the first time later this year."
     Auxiliary power units provide power to aircraft while they are on the
 ground and in-flight back-up power. The APS 5000 APU is rated at 1,100
 shaft horsepower and is designed to start and operate throughout the full
 range of the 787 operating envelope up to 43,000 feet. Hamilton Sundstrand
 Power Systems, based in San Diego, Calif., currently has more than 13,000
 APUs in commercial and military service.
     "Every step forward on this program, including the success of the cold-
 weather tests for the APU, is another signal of our progress in meeting our
 customers' expectations," said Ron Hinderberger, leader of the 787
 Propulsion team for Boeing. "This is a big year for us and it is great to
 see Hamilton Sundstrand and our other partners proving out the technologies
 of the 787."
     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 $8 billion in
 revenue for Hamilton Sundstrand over the life of the program.

 approximately 17,000 people worldwide and is headquartered in Windsor
 Locks, Conn. Among the world's largest suppliers of technologically
 advanced aerospace and industrial products, the company designs,
 manufactures and services aerospace systems and provides integrated system
 solutions for commercial, regional, corporate and military aircraft. It
