Rolls-Royce Holdings Plc says one of its line of Indianapolis-made engines is expected to hit a significant milestone this year. The M250 line of aircraft engines “will pass the 250 million flight hour milestone in 2017, a rare occurrence among any engine product in aviation history,” Rolls-Royce said.
Rolls-Royce introduced the engine in the 1960s to power U.S. Army helicopters. Since then, it has been adapted for use in multiple types of military and commercial helicopters, including those used in the oil and gas, tourism, law enforcement, medical evacuation, and other industries and for private uses.
About 16,000 M250 engines are in service around the world, Rolls-Royce said.•
