Keystone Gains Dual M250-C47E Testing Certification
The testing certification also expands Keystone Turbine Services' capabilities to work on the complete M250 engine product line.

Precision Aviation Group’s Keystone Turbine Services announced this week that its two all-digital engine test cells are fully OEM correlated and certified for testing the complete series of Rolls-Royce M250-C47E Fadec engines for both pre- and final testing services. The engine type powers Bell’s 407GXi light single helicopter, the U.S. Navy’s Fire Scout MQ-8C unmanned rotorcraft, and the MD 540F helicopter.
