About the Rolls-Royce M250

It powers aircraft such as the Bell 206 JetRanger, Bell 206L LongRanger, Bell 407, MD 500 and others. When buying or overhauling a turboshaft like this, the figures that matter most to operators are time since overhaul, program enrolment (engine maintenance program vs time-and-material), and the cost of the next shop visit — all of which a seller quote should make clear.
