Maintenance MNYR085K PQ3524CE Certified Repair Station FAA-PMA Our Legacy Mike Kelley started doing aircraft maintenance in 1977 in a hangar on Wellington’s municipal airport, hanging out his shingle as Air Plains Services , a nod to both the Great Plains of southcentral Kansas and the region’s reputation for aviation. Just a few miles north is Wichita, home to aviation legends Clyde Cessna, Walter Beech and Lloyd Stearman and known today as the Air Capital of the World. It wasn’t long, though, before Kelley and his wife, Carolyn, turned a passion for flying and for innovation into an industry leader as an airplane transformer, turning legacy Cessna pistons into power singles with STCs for Extreme Performance engine upgrades. Forty-five years later, the company still ranks as the leader in engine upgrade STCs and has added a wide range of avionics upgrades, propeller STCs, PMA parts, specialty manufacturing, interiors, and, of course, full aircraft maintenance.

Engine Pre-heater Protect your valuable investment from a cold awakening.

As the legacy aircraft fleet ages the original propeller installed by the factory may have become obsolete and parts now very difficult to find. Contact us today for specifics on approved diameters for your aircraft. Besides greatly improving the aesthetics of your airplane when parked on the ramp or in your hangar reduced vibration is one of the biggest advantages of a three blade propeller. The McCauley Blackmac McCauley is offered for your airplane in different diameter lengths. The extra blade adds static thrust, which improves takeoff acceleration and climb. A three blade prop lessens the vibration in a way that most people find more comfortable. ​ ​ STC SA01952WI Trailblazer Cessna 180 Model Eligibility: Engine Eligibility: 180 All IO-550 STC SA01952WI Trailblazer Cessna 182 Model Eligibility: Engine Eligibility: 182H J, K, L, M, N, P, Q, R IO-550 STC SA00152WI Scimitar Cessna 182 Model Eligibility: Engine Eligibility: 182H, J, K, L, M, N, P, Q, R IO-520, IO-550 Hartzell Prop Options Air Plains Services also offers a number of optional propellers both metal or composite that are available for further consideration when making the selection for your mission. ​

SHOP NOW About Us Mike Kelley started doing aircraft maintenance in 1977 in a hangar on Wellington’s municipal airport, hanging out his shingle as Air Plains Services , a nod to both the Great Plains of southcentral Kansas and the region’s reputation for aviation. Just a few miles north is Wichita, home to aviation legends Clyde Cessna, Walter Beech and Lloyd Stearman and known today as the Air Capital of the World. It wasn’t long, though, before Kelley and his wife, Carolyn, turned a passion for flying and for innovation into an industry leader as an airplane transformer, turning legacy Cessna pistons into power singles with STCs for Extreme Performance engine upgrades. Forty-five years later, the company still ranks as the leader in engine upgrade STCs and has added a wide range of avionics upgrades, propeller STCs, PMA parts, specialty manufacturing, interiors, and, of course, full aircraft maintenance. “The performance of my C-180 after the Engine Upgrade has far exceeded my expectations! The interior and avionics installation are works of art, as well. However, it was the people at Air Plains that made a major undertaking a pleasurable experience.” ​ Kyle, AZ C-180 300HP “I really wanted more power and the Air Plains upgrade has it. We’re getting a big increase in speed and 1000fpm climb rate, and we’re really pleased with the gas consumption. Air Plains is just so easy to deal with and I love great value in service!” ​ Jeff, OK C-172 180HP “ Airplains took my inquiry from Europe very serious and they have delivered an outstanding job and service. The 300HP engine has taken me safely three times over the North Atlantic. I can well use that power here on small strips and in the mountains in Switzerland” ​ Alfred, CH C-182 300HP
