Textron Aviation has opted for GE Aviation's all-new turboprop engine to power its single engine turboprop (SETP). The 1300 shaft horsepower (SHP)-rated turboprop engine will be the first entry in GE's new family of turboprop engines designed specifically for business and general aviation aircraft in the 850- to 1600-SHP range.

Brad Mottier, Vice President and General Manager of GE Aviation's Business & General Aviation and Integrated Systems division, said during the recent announcement that “this new engine features an industry-best 16:1 overall pressure ratio (OPR), enabling the engine to achieve up to 20% less fuel consumption and 10% more cruise power compared to competitor offerings in the same size class, which usually feature an OPR of 9:1. It also has 4000-6000 hour MTBO,” or mean time between overhauls, which is about 30% longer than with existing engines.
