Pratt & Whitney’s PW4000-94 Engine Marks 35 years and 150 Million Flight Hours

Pratt & Whitney announced that the PW4000-94-inch engine has surpassed 150 million flight hours and 35 years of operational experience. Over 2,500 engines have been delivered since entry-into-service in 1987. The PW4000-94-inch engine currently serves more than 70 customers in 30 countries, powering Boeing 747/767 and MD-11, Airbus A300/310 and the KC-46A aircraft across passenger, cargo, and military missions.

The 94-inch engine was the first model in Pratt & Whitney’s high-thrust family for large aircraft, covering a range of 52,000 to 62,0000 pounds of thrust. Over 55% of the fleet serves the cargo industry.

“This milestone is a testament to the PW4000-94-inch engine’s legacy of reliability and performance,” said Bernie Zimmerman, vice president, Operational Commercial Engines, Pratt & Whitney. “The 94-inch offers excellent operational flexibility and fuel economy and lower noise versus the competing engine.
