Rolls-Royce has delivered its 250th engine to Enstrom Helicopter Corporation. The RR M250-C20W has powered the Enstrom 480B for more than 25 years, first entering service together in 1993. Engine number 250 will power a helicopter for the Botswana Police-Air Support Branch as part of a deal announced this week by Enstrom.

The 480B is Enstrom's flagship turbine helicopter, known for its combination of safety, stability, comfort and value. The five-seat aircraft serves as a military trainer, and is well suited for law enforcement, emergency medical and commercial, agricultural and private operations.

Jim Payton, VP of civil helicopter sales at Rolls-Royce says: “We're proud of the strong relationship we've built with Enstrom Helicopter, exclusively powering the 480B for nearly three decades. To deliver 250 engines is a significant milestone and compelling testament to the exceptional fit and performance of the M250.”

Enstrom president Matt Francour adds: “The relationship between Enstrom and Rolls-Royce has been just like its engines; strong and reliable. We look forward to maintaining our partnership for many years to come.”

The proven Rolls-Royce M250 engine has powered more than 260 million flight hours of dependable service. More than 33,000 M250 engines have been delivered to the marketplace.
