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

Air Plains Services , a world leader in general aviation engine and avionics upgrades, announced today it has gained Parts Manufacturing Approval (PMA) from the Federal Aviation Administration for its forward spinner bulkhead  for a number of Cessna 172 models. This component joins the Air Plains parts catalog that includes the Cessna 172 aft spinner bulkhead PMA component and the forward and aft bulkhead assemblies designed specifically for any Cessna 172 with the Air Plains 180hp engine upgrade STC. “We’re always looking to expand our PMA range of parts for Cessna pistons, focusing on high quality and low market cost,” said Katie Church, Air Plains president. “We’ve already gained design and production expertise for this part through the STC process, so expanding the PMA product line to include legacy aircraft models was a logical extension.” The forward PMA spinner bulkhead (Part #APS0550321-4) is approved for Cessna 172 I through P models and for French-made 172 L through P models. Air Plains produces hundreds of PMA and STC parts for a wide variety of Cessna single-engine piston such as components for the air induction system including airboxes, collars, gaskets, adjustable brackets and baffles assemblies, all available at the company’s online store . For information about the new spinner bulkhead or any Air Plains product, call 1-800-752-8481 or +1-620-326-8904 or send an email to sales@airplains.com .

WELLINGTON, KS (July 31, 2025) – Air Plains Services , a world leader in general aviation engine and avionics upgrades, announced today it has gained Parts Manufacturing Approval from the Federal Aviation Administration for the airbox filter seal assembly  for Cessna 172 L and M model aircraft. “The seal assembly is an important part of the cooling system and plays a key role in proper CHT management,” said Katie Church, president of Air Plains. “We specialize in PMA parts for Cessna piston, particularly the cooling system, and when we find ways to improve on an original design, we want to add it our product range.” Mechanics at Air Plains report the absence of the filter seal assembly on many L and M model Cessna 172 Skyhawks coming in for engine upgrades. This can cause a change in designed air flow over the engine, resulting in higher CHTs, as much as 10 to 15 degrees F. “The seal is essential to achieve a greater pressure differential in the engine compartment that strengthens the flow of cooler air over the engine,” Church said. “As we’ve done with other components such as the airbox, we’ve made it better, easy to install and less expensive than other options.” Air Plains opted for a special, lightweight polycarbonate plastic due to its higher temperature resistance, weight and strength. The fiberglass-reinforced silicone material is a single piece seal that provides the best differential pressure between the upper and lower cowl and is designed for easy installation. Air Plains offers a wide range of PMA parts for the induction system including airboxes, collars, gaskets, adjustable brackets and baffles assemblies, all available at the company’s online store . For information about the new airbox filter seal assembly or any Air Plains product, call 1-800-752-8481 or +1-620-326-8904 or send an email to sales@airplains.com . ### Air Plains Services, based in Wellington, Kansas, is a leader in general aviation aircraft upgrades, specializing in high performance engine upgrades  for most Cessna 172, 180 and 182/182RG piston aircraft, avionics systems  and components as well as custom avionics panels, high quality spare parts  and enhanced performance systems, and aircraft modification and maintenance . Air Plains stands apart from most other companies, shipping complete, ready-to-install engine upgrade kits anywhere in the world. Air Plains Services, serving the aerospace industry for more than 40 years, is also the home of the Inpulse ADI modification that allows high compression aircraft engines to use 91 octane auto fuel. Air Plains also owns Petersen Aviation  of Minden, Nebraska, known worldwide for its wide inventory of Supplemental Type Certificates (STCs) that allow general aviation aircraft owners to use less expensive, unleaded auto fuel instead of 100LL avgas.  For more information, visit the Air Plains website at www.airplains.com  and follow the company on the Air Plains Facebook  and Instagram  pages. For information on Air Plains’ Inpulse system for unleaded auto fuel, visit www.flyinpulse.com .

Air Plains Services, a world leader in General Aviation engine and avionics upgrades, announced today it has acquired Petersen Aviation of Minden, Nebraska. Petersen developed Supplemental Type Certificates (STC) that allow general aviation aircraft owners to use less expensive, unleaded auto fuel instead of 100LL avgas. Petersen owned STCs for 48 engine types powering more than 100 airframes around the world, all of which now transfer to Air Plains. “We’ve been working with Todd Petersen for more than 10 years and we’re so excited he has entrusted us to continue his family’s legacy of innovation and customer service through this acquisition,” said Air Plans President Katie Church. “Todd developed our Inpulse anti-detonation injection STC for high-horsepower engines to burn auto fuel so we now offer the full range of auto fuel STCs for the industry.” For the immediate future, Air Plains will continue to sell the STCs through the Petersen website as well as by contacting Air Plains.
