Fuel Injection

Anytime an engine generates more than 260 HP we believe that fuel injection provides the needed even fuel distribution on each cylinder to make your flying worry free. You will achieve more predictable CHTs and EGTs and enjoy a smoother ride with reduced vibration. This minimizes premature component failure. Did we mention 0% carburetor ice issues?


Dual Magneto

Our STC upgrade addresses one of the most critical design challenges of your current engine - The single housed magneto. Some of the issues are cams loosening, impulse couplings failing and magneto movement. All these failure modes result in either a drastic reduction of power or complete failure of the engine.

With Air Plains there are a few options to get 180 horsepower into your Skyhawk. We do not sell the "STC Paperwork" only because we believe that the kit parts that we offer with the engine upgrade is the "secret sauce" to a complete, safe and successful installation. We have added several more parts over the 40 years with our continual engineering. Our goal is to make the installer's job as easy as possible. Installation instructions and blueprints safeguard the procedures and standards for installation and maintenance of your new engine... no matter where you choose to have it installed. Did you know that in the state of Kansas there is no sales tax on aircraft maintenance or modification?​​​
