[4] Its Electronic Engine and Propeller Control (EEPC) system received EASA type certification in late 2016.

The Diamond Dart 550 military trainer is due to fly it in early 2018 and it will be certified on the Thrush 510G crop duster in this year.

[1] The two-shaft, reverse flow design is derived from the Walter M601: its core features a two-stage axial and single-stage centrifugal compressor, an annular combustor and a single turbine stage, and its propulsion section is powered by a single-stage turbine driving a two-stage planetary gearbox.

GE redesigned the compressor with 3D aero to improve its pressure ratio and upgraded the hot section and turbine stages with modern metal alloys for higher temperatures with the same durability.

[5] The H75-100 weighs 94 lb (43 kg) more than the equivalent PT6 but pioneers single lever electronic propeller and engine control in general aviation, for an initial TBO of 4,000 hr which could be increased with experience.
