PRATT & WHITNEY PW4000-POWERED 767 EARNS 180-MINUTE ETOPS CERTIFICATION

 EAST HARTFORD, Conn., Aug. 3 /PRNewswire/ -- The Pratt & Whitney PW4000-powered Boeing 767 has been certified by the Federal Aviation Administration (FAA) for 180-minute extended twin operations (ETOPS), Pratt & Whitney announced today.
 The PW4000-powered 767 is now permitted to fly efficient, extended routes that may take the aircraft up to three hours away from an alternate airport. ETOPS certification is the hallmark of an engines' reliability.
 "FAA certification confirms what our customers have been experiencing in the field -- the PW4000/767 combination is one of the most reliable aircraft in service today," said Thomas Harper, Pratt & Whitney's PW4000 program director.
 The PW4000 entered service in 1987 powering the Airbus A310 twinjet. Today, it has amassed over six million flight hours. It powers every model of every wide-body aircraft in service or in development. Its 65 customers are located throughout the world. More than 2600 engines have been ordered to date.
 "Reliability is key to an operator," Harper added. "It is our goal at Pratt & Whitney to have the most reliable engines in the industry. This ETOPS certification proves we are making progress."
 The PW4000 family spans a thrust range of 50,000 to over 100,000 pounds. The 94-inch fan version, similar to that just ETOPS-certified on the 767. has a thrust range of 50,000 to 62,000 pounds. The recently released Phase III performance improvement further reduces fuel consumption and operating temperatures, thus improving reliability and durability even more.
 Nearing FAA flight certification is a 100-inch variant capable of producing 64,000 to 74,000 pounds of thrust. This engine, designated the PW4168, goes into service next year on the Airbus A330 twinjet.
 In development testing is a 112-inch fan version covering thrusts over 74,000 pounds. Called the PW4084, this powerplant enters service in 1995 when it launches Boeing's new 777 supertwin.
 Pratt & Whitney is an operating unit of United Technologies Corporation (NYSE: UTX) based in Hartford, Conn.
