Boeing 757-300 Powered By Pratt & Whitney Engines Earns FAA Certification SEATTLE, June 6 /PRNewswire-FirstCall/ -- The first Boeing (NYSE: BA) 757-300 airplane powered by Pratt & Whitney PW2000 engines today earned certification from the U.S. Federal Aviation Administration after successfully completing a three-month flight-test program. The Pratt & Whitney-powered 757-300 also received validation from Europe's Joint Aviation Authorities. Until now, all of the 757-300s have been built with Rolls-Royce engines. "With the certification of the Pratt & Whitney engines on the 757-300, Boeing expands customer choice and offers commonality for airlines that operate 757-200s with Pratt & Whitney engines," said Carolyn Corvi, 737/757 vice president and general manager. The first Pratt & Whitney-powered 757-300 is destined for Northwest Airlines. The North American carrier currently operates a fleet of 55 757-200s that are equipped with Pratt & Whitney engines. Northwest Airlines will take delivery of the first of 16 757-300s this summer. The PW2000 engine family builds on the success of the 757-200s, which are offered with PW2037 and PW2040 engines. A higher thrust version of the engine -- the PW2043 -- also earned certification and provides 43,000 pounds of thrust and additional performance capability for the 757-300. The efficient 757-300 is the largest single-aisle twinjet, and it has the lowest operating cost per seat-mile of any single-aisle airplane and mid-sized airplane in its class. Seating about 243 passengers in a typical mixed configuration, the airplane's interior is based on the award-winning design of the Boeing 777, using state-of-the-art lighting and design concepts to enhance the feeling of spaciousness. After proven success in the European inclusive tour operator market, the 757-300 debuted in scheduled, dual-class service in the North American market last year and the European market this year. With the delivery to Northwest Airlines this summer, the single-aisle jetliner will have Roger EWROPS
