The PW4000-94-inch engine is currently used by more than 70 different companies across 30 different nations to power aircraft for passenger, cargo, and military missions, including the Boeing 747/767, MD-11, Airbus A300, and KC-46A.
Pratt & Whitney has announced that the PW4000-94-inch engine has surpassed 150 million flight hours and 35 years of operational experience. Since their introduction to service in 1987, more than 2,500 engines have been delivered. The PW4000-94-inch engine currently powers more than 70 customers’ aircraft across 30 nations, including the Boeing 747/767 and MD-11, the Airbus A300/310, and the KC-46A for passenger, cargo, and military missions.
The 94-inch engine, with a thrust range of 52,000 to 62,0000 pounds, was the first model in Pratt & Whitney’s high-thrust family for large aircraft. The cargo industry is served by more than 55% of the fleet.
“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. It’s an engine that’s been proven on a variety of applications — passenger, cargo, and military,” he further added.
In 1989, United Airlines’ Boeing 747-400 fleet received the PW4000-94-inch engine and starting in 1991, the Boeing 767-300 fleet, for a total of 81 aircraft.
“United has appreciated the reliability, great fuel economy and low maintenance costs of these engines,” said John Wiitala, Vice President of Technical Services at United. “It’s no surprise that these Pratt & Whitney engines have served United and our customers well for 33 years and counting.”
