Market Wire, June, 2006

Pratt & Whitney Canada Corp. (P&WC), a United Technologies Corp. (NYSE: UTX) company, has received Transport Canada type certification for its new PW980A auxiliary power unit (APU). The PW980A will provide power for main engine starting, environmental control and electrical systems on the Airbus A380, the world's largest commercial passenger jet. The certification enables P&WC to obtain Transport Canada's manufacturing approval and thereby begin delivery of production PW980A engines.

"The certification of the newest and largest member of our PW900 family is an important milestone. The PW980A will continue the legacy of the PW900 family as the industry benchmark for APU reliability and durability," said Alain M. Bellemare, president, P&WC.

The PW980A sets new standards for reduced noise and emissions. A derivative of the highly successful PW901A, it incorporates the latest technology advances in areas such as aerodynamics, materials and engine controls to offer superior levels of reliability, durability and efficiency expected by major airlines.

"The PW980A is the largest APU in the market, with power equivalent to more than 1,800 hp," said John Saabas, senior vice president, engineering & operations, P&WC. "Its successful development was made possible through integrated product teams among P&WC, Hamilton Sundstrand, which also is part of UTC, and Airbus."
