Rolls-Royce Model 250 Turboprop to Power New Executive Transport Aircraft

Released on Sunday, July 27, 2008

The Turbine 340, a new Rolls-Royce Model 250-powered executive transport aircraft, was unveiled today by O&N Aircraft Modifications, Inc. at the Rolls-Royce exhibit at EAA AirVenture.

The aircraft is a twin-engine Cessna 340 converted from its AvGas piston engine configuration to incorporate Model 250 B-17 series turboprops. The Turbine 340 made its successful first flight in early July and will begin extensive flight testing next month to complete its FAA Supplemental Type Certification.

Diane Olson, O&N President, said: "The launch of this executive transport aircraft opens up a new market for O&N, providing a comfortable, cabin-class aircraft capable of flying into and out of very small airports.

"Drawing upon all the advantages of turbine power, the Turbine 340 is the ideal choice for individuals and companies requiring twin-engine operations and looking for a reliable, competitively-priced choice."

Ken Roberts, President of the Rolls-Royce Helicopter Engine business, said: "The introduction of the Turbine 340 builds upon a successful relationship with O&N which began with the Model 250 turboprop-powered Silver Eagle P210. Fourteen years later, O&N is soon to celebrate the 100th delivery of this very popular, single-engine aircraft.

"Rolls-Royce looks forward to similar success on the Turbine 340 aircraft, tailoring our Model 250 turboprop to suit the unique needs of our customer."

The Model 250 engines for the Turbine 340 will be assembled and tested on a newly-commissioned small engine assembly line at the Rolls-Royce facility in Indianapolis, Indiana.

Rolls-Royce has served the light turbine general aviation market for over 40 years, producing 30,000 Model 250 engines, including 1400 Model 250 turboprops that have accumulated nearly seven million hours of flight experience.
