Pratt & Whitney Canada's PurePower® PW814GA and PW815GA Engines Receive Type Certification to Power New Gulfstream Business Jets

LONGUEUIL, Quebec, Tuesday, February 17, 2015

Pratt & Whitney Canada (P&WC) announced today that it has received Transport Canada type certification for its PurePower PW814GA and PW815GA engines, which will power the new Gulfstream G500 (range of 5,000 nautical miles) and G600 (range of 6,200 nautical miles) business jets respectively. P&WC is a United Technologies Corp. company (NYSE:UTX).

Certification of these two engine models follows Gulfstream's recent unveiling of its new G500 and G600 business jets and the news that P&WC's PurePower PW800 engines were selected to power these next-generation long-range and ultra-long-range aircraft. In addition to the engines themselves, P&WC is providing Gulfstream with the Integrated Power Plant System (IPPS), which comprises the engine, nacelle, and thrust reverser systems.

"Transport Canada type certification of the PurePower PW814GA and PW815GA engines as well as Gulfstream's selection of the PurePower PW800 family represent major achievements for P&WC," said John Saabas, president, P&WC. "We are very proud to power Gulfstream's new business jet family."

During rigorous endurance testing, simulating various aircraft missions, the PW800 engine has achieved more than 3,300 hours of evaluation. This includes over 350 flight hours on P&WC's advanced Boeing 747SP flying test bed aircraft. Additionally, the PurePower PW800 engine's advanced common core technology – leveraged in six PurePower engine applications – has amassed 15,000 testing hours in total.

"The PurePower PW800 engine has successfully achieved all of its objectives under a broad range of environmental and operating conditions, exceeding expectations," said Walter Di Bartolomeo, vice president of Engineering, P&WC. "We are thrilled with the engine's performance, fuel efficiency and environmental characteristics, which put it far ahead of anticipated standards on emissions and noise levels and ensure its best-in-class availability."
