The excitement over this aircraft is high and has allowed us to pre-sell charter time in the plane. We fully expect to keep four-seven whiskey flying day after day.” “I’m already starting to get calls from potential H80 customers wanting to demo the plane”, continued Drumm.

Blake Tumbleson, Owner of Tumbleson Aviation Consulting handles aircraft sales for the company through a strategic alliance. “This program is about to be the talk of the industry. Smyrna Air Center has a winner with the Power90 Conversion and I’m so pleased to represent this product.”

“Power 90” is an FAA-Approved STC Engine Conversion, owned by Smyrna Air Center for Beechcraft King Air models 90, A90, B90, C90, and E90 aircraft. The conversion program includes a full phase 1-4 inspection, removal of the factory installed engines, installation of two GE brand new H80 engines, and installation of two brand new Avia 5-Blade Quiet Props.

The GE H80 engine combines the M601 engine with GE’s 3-D aerodynamic design techniques and advanced materials to create a more powerful, fuel-efficient, and durable engine than the already efficient M601. GE Aviation’s Business & General Aviation Turboprops have more than 1,600 M601 engines in service that have accumulated more than 17 million flight hours on 30 applications.

The GE H80 engine requires no fuel nozzle cleanings due to its unique slinger ring design, no required hot section inspections, and 3,600 flight-hours, and 6,600 cycles between overhauls. Owners can expect significantly enhanced hot-day takeoff performance and high altitude cruise speeds
