NG Aircraft, the company behind the new Fokker 70/100NG, is planning to have the aircraft powered by Rolls-Royce BR725s, the same engine type that powers the Gulfstream G650.

Industry executives close to NG Aircraft say the airframer has chosen the BR725; however, NG Aircraft’s managing director, Maarten van Eeghen, declined to confirm this when contacted by Aviation Week. “I’m not able to divulge this as we are still in final negotiations,” he says.

One industry executive says van Eeghen may be reluctant to comment publicly on this issue, because even though the aircraft maker may have made a decision internally, it still needs to secure commitments from the engine maker for product support.

But the fact that the BR725 already powers the Gulfstream G650 and an earlier variant of the engine powers the Gulfstream G550 and Bombardier Global Express means this engine type is well-supported. There are maintenance, repair and overhaul firms in markets around the world certified to do light and heavy maintenance checks on the BR710 and will be certified to work on the BR725.

Gulfstream also speaks very highly of the BR725. The U.S. aircraft maker’s senior VP-marketing and sales, Larry Flynn, says the engine is about 10% more fuel-efficient than the variant used on the G550. He also says the engine type is well supported by Rolls-Royce, which has a power-by-the-hour program.

Rolls-Royce has a strong historical association with Fokker. Rolls-Royce Tay engines power the original Fokker 70 and Fokker 100. Other Fokker aircraft, such as the F27 and F28, are also powered by Rolls-Royce.

NG Aircraft’s decision gives a major boost to Rolls-Royce’s commercial narrowbody engine business, which has suffered some major setbacks recently.

Rolls-Royce is a partner in the International Aero Engines (IAE) consortium, which makes IAE V2500 engines. IAE lost out to Pratt & Whitney on the Bombardier CSeries and Mitsubishi Aircraft MRJ engine selection, and IAE lost out to CFM International on the Commercial Aircraft Corporation of China C919.
