PRATT & WHITNEY PW4000S SET RELIABILITY STANDARD ON NORTHWEST AIRLINES 747-400

 PRATT & WHITNEY PW4000S SET RELIABILITY STANDARD
 ON NORTHWEST AIRLINES 747-400
 EAST HARTFORD, Conn., April 27 /PRNewswire/ -- Four PW4000 engines delivered on a Northwest Airlines 747-400 in 1989 have set a new industry milestone for dependability. They have never been removed for maintenance after more than 10,000 hours of day-to-day service.
 Northwest took delivery of the aircraft on Aug. 22, 1989. Since then, the aircraft's engines have not been removed for any reason. "We've had individual engines remain on wing for over 20,000 hours," said Nick Tomassetti, executive vice president of Pratt & Whitney's Commercial Engine Business. "To have an entire shipset of four engines remain on the wing for more than 10,000 hours speaks well for the PW4000's reliability."
 Northwest's senior vice president -- Technical Operations, Terry Rendleman, said, "PW4000 reliability has been nothing short of excellent. We have about 50 PW4000s in service, and they are all performing to the highest level of reliability. We have some engines with more than 11,500 first run hours and they just keep going."
 Keeping engines on the wing means the aircraft remains in service continuing to generate revenues. It also reduces maintenance costs by eliminating unscheduled engine removals. "Any time we can go nearly three years with engines on the wing we keep our cost down and improve our competitive position," Rendleman said.
 Another measure of reliability is dispatch rate. The PW4000 fleet has a dispatch reliability of 99.88 percent. This is the best dispatch rate of all FADEC (full-authority digital electronic control) engines in service. This means for every 10,000 departures, only 12 will be delayed for engine related causes. "A big part of passenger comfort is leaving the gate on time, and we pride ourselves on being the on-time airline," Rendelman said.
 "All of the advanced technology we put into the PW4000 has shown its worth in outstanding performance each day at airlines around the world," Tomassetti said.
 To date, nearly 2,800 PW4000 engines have been ordered by 60 customers worldwide. The engine has captured about 55 percent of all wide-body engine competitions since service introduction in 1987.
 The Pratt & Whitney PW4000 family spans a range of 50,000 to more than 100,000 pounds thrust. In service today at Northwest and other leading airlines is a 94-inch fan version generating from 50,00 to more than 62,000 pounds of thrust. Currently at test is a 100-inch fan variant capable of producing over 70,000 pounds of thrust. This engine, the PW4168, will be certified in 1993 and enters service in the summer of 1994 on the A330. The PW4084, the 112-inch fan engine, goes to test this summer. It's the sales leader for Boeing's new 777 supertwin and is scheduled for certification at 84,000 pounds thrust in mid 1994.
 The entire PW4000 family features the same common core. The fact it's already service-proven will enable both the 100-inch and 112-inch engines to meet early ETOPS (Extended Twin Operations) criteria. "The same reliability Northwest is experiencing with today's engine will be in our growth engines -- and then some," Tomassetti added.
