It is simple. We believe that 180HP and a fixed pitch propeller provides the best combination of power and reduced complexity for a Cessna 172. The proven and reliable factory new Lycoming O-360-A4M engine comes complete from Air Plains with roller tappets, Slick Magneto, EIS (Electronic Ignition System), wiring harness, spark plugs, carburetor and ring gear. The engine is paired with a light weight Sky-Tec starter and Plane-Power alternator.
We provide an all-encompassing kit during the upgrade. We like to call it a NEW firewall forward upgrade. Our goal is to provide all the hardware needed to complete the installation with ease.

All propellers have been matched to provide the best combination of airframe and powerplant. Propeller blades with different pitch rage are available if your goal is to achieve an optimal cruise speed or climb rate. The available fixed pitch propeller enables a light weight and low maintenance benefit.
Expand your envelope. One of the best benefits of our upgrade is the ability to carry additional weight on your flights. It adds flexibility on your range planning and an additional safety margin. This is why we developed STC SA2196CE. Your Cessna 172 will be a true 4 seat airplane with 1000 LBS useful load.
