  • Excellent power-to-weight ratio

  • 62 applications to date, 43 of which were upgrades of piston-engined designs

  • More than 1,400 engines produced to date

The M250 turboprop was developed from the famous Model 250 turboshaft. The first 317 shp M250-B15 turboprop spawned a family of highly successful derivatives, culminating in today's 450 shp M250-B17F Series. The engine found popularity due to its small size and high power-to-weight ratio, which make it ideal for turbine conversions of existing piston-engined designs.

The M250 FIRST network provides an opportunity to choose support from one of 35 authorised facilities and is the most diverse and customer-focused gas turbine engine support network in existence today.  To learn more about the service options and quality products visit www.m250first.com.

The M250 Series II turboprop engines have a two-shaft modular design featuring four to six-stage axial and single-stage centrifugal compressors, a two-stage LP turbine, two-stage HP turbine with a hydromechanical fuel control system, and a gearbox with 2,800rpm output. Compressed air is routed to the aft end of the engine for combustion, with exhaust gases exiting upward from the middle of the engine.

Applications: Grob G120TP, GippsAero GA10, Extra EA-500, Fuji T-7, Soloy Cessna 206 Mark 2, O&N Silver Eagle and Cessna 340, Vulcanair aViator, Tradewinds Bonanza, and B-N Defender
