M250 turboprop

One of the industry's most popular 300-450shp turboprop engines

Product details

  • Excellent power-to-weight ratio
  • Extremely compact design
  • 62 applications to date, 43 of which were upgrades of piston-engined designs
  • Over 1,200 engines produced to date
  • Recent applications include the Extra EA-500, Fuji T-7, Soloy Cessna 206 Mark 2, O&N Silver Eagle I, II, and III, Vulcanair Aviator and Tradewinds Bonanza

As a part of the M250® family, the first 317shp Model 250-B15 is part of a family of highly successful engines for light fixed-wing aircraft, culminating in today's 450shp Model 250-B17F.

The M250 turboprop has found popularity due to its small size and high power-to-weight ratio, which make it ideal for Original Equipment Manufacture Type Certified designs and for Supplemental Type Certificate conversions of existing piston-engined designs. Over 1,200 M250 turboprops have now been produced, with over 5 million flight hours.

These lightweight, high power engines operate on all certified aircraft fuels, a feature favoured by operators who take them into remote regions of the world. Their legendary reliability, combined with vibration free turbine smoothness, gives an easy ride to both the passengers and the airframe components. Cabin noise levels can often be cut by over 10 dBA, enabling pilots and passengers of M250 turboprop powered aircraft to converse at normal levels, without headsets.

The M250 turboprop enjoys the same world-class global support as the turboshaft family, and benefits from a continuous improvement culture which has seen the M250 remain at the forefront of small gas turbine engine design.

The latest generation M250-B17F turboprop is common to the M250-C20R+ turboshaft, and develops 450shp. The M250 turboprop has approximately 20 current applications, including the Grob G 120TP, Fuji T-7 trainer, B-N Group Defender, O&N Cessna P210 Silver Eagle, Soloy Cessna MkII 206 and Tradewinds Turbine Bonanza.
