We offer several aircraft upgrades such as Flint Tanks, gross weight increase, engine monitors, interior refurbishment and more... 1 2 3 4 5 6 1530 ºF 900 460 ºF 200 Engine Data Monitor Monitoring the health of your engine is crucial after a big investment on your powerplant. We recommend that our customers should take advantage of an electronic engine monitor during an upgrade. Because the engine is removed from the aircraft, we are able to reduce the installation time and carefully mount components on the engine when it is on the engine stand.

AVIONICS Reliability Performance Starts EIS reduces the scheduling headaches and downtime by providing operators with a 2,400 hour operating service time. More consistent spark energy with higher accuracy. 2 Lbs. lighter than a Bendix magneto Minimize wear and tear on starters and electrical systems with controlled timing at TDC below 400 RPM. Utilizes solid-state electronics eliminating the need to disassemble the SIM and introducing maintenance related failure.

Fuel Tank Increase the range of your aircraft with wing tip tanks from Flint Aero Inc. Carrying more fuel will enable you to deviate from weather, make your trip with less delays and plan a better route to find the cheap fuel. Most customers leave our shop with extra 23 gallons of fuel on their wing because it is a no brainer. Add another 2.5 hours of fuel to complete your mission. GAMI Injectors GAMI injectors are designed to deliver the specific fuel amount to each cylinder that will compensate for the fuel and air imbalance inherent in the fundamental design of the engine fuel/air system. Turbine Smooth On our 300HP upgrades we offer the ability to modify and reuse your existing engine mount or you can opt to install the Seaplanes West/Acorn Welding engine mount to enhance your ride experience. Engine Pre-heater Protect your valuable investment from a cold awakening. In less than a minute, a single cold start without proper preheating can produce more wear on your piston engine than 500 hours of normal cruise operation. New Interior We can all agree that there’s nothing better than the fresh smell of a new interior in your aircraft.

Our expertise is listening to the customer and applying our know-how. We perform maintenance, STC upgrades and modifications on single engine Cessna aircraft. 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.

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 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.
