  • Air Plains Services Announces Transport Canada Approval for its Unique Cessna 172R Model 180hp Upgrade STC

    WELLINGTON, KS (Feb. 1, 2024) – Air Plains Services, a world leader in General Aviation engine and avionics upgrades, announced today it has gained approval from Transport Canada for its FAA-approved Supplemental Type Certificate that upgrades Cessna 172R model aircraft to 180hp without a complete engine change. The Air Plains STC kit for R model Skyhawks includes a new propeller that allows the standard derated Lycoming IO-360-L2A to operate at 2,700 rpm instead of the normal 2,400 rpm, thus generating 180hp. In addition to increased performance for the airplane, the upgrade offers a 100-pound increase in payload. “Confirming approval for this STC from Transport Canada is the type of service we’re happy to perform to give our customers the confidence they want in buying from Air Plains,” said Katie Church, Air Plains president. According to Transport Canada, a number of international STCs such as this one can be approved for use in Canada based solely on the home nation’s certification. With FAA approval already in hand for the Air Plains STC, it qualified for Canadian approval without a separate approval process. “Our unique STC kit, shipped almost anywhere in the world, is a great option for 172R model owners to get more performance from their airplane with just a new propeller and a small upgrade kit,” Church said. “The payload increase makes it a true four-place aircraft which can be a game-changer in a training environment or allows it simply to carry more luggage on a family vacation.” For more information about any of Air Plains products or services, call 1-800-752-8481 or +1-620-326-8904, or visit For online shopping, visit the Air Plains web store at

  • Cessna 172 PMA Airbox

    Cessna 172 Airbox, FAA PMA Approved Replacement Part Number: 0552113-11 Model Eligibility: Cessna 172I, 172K equipped with the Lycoming O-320-E2D engine. Cessna 172 Airbox Description: As the leader in firewall forward STC products for Cessna™ single aircraft Air Plains is all too familiar with customers "airbox woes".  Until now customers had to choose between temporary repairing their airbox or purchasing a new airbox from Cessna™.  The problem is that both options can be very expensive, and the final product is still an airbox susceptible to several common issues.​ Air Plains now offers customers a third option; our FAA-PMA approved APS0552113-11/APS0552113-13 airbox provides MORE DURABILIY and MORE VALUE over previous options for 172 owners.  Furthermore, for fleet operators, our airboxes are more universal.  Both the APS0552113-11 and APS0552113-13 airboxes are identical and approved on all 172I, K, L, M, F172L, and F172M applications, this means you don’t need to keep two on hand.​ When we developed our PMA airbox we looked at the common issues with the factory airbox and identified several areas for improvement:​ Our airbox features structural adhesive reinforcement in the highest stress areas, this distributes the stress between the skins and prevents the common cracking and collar separation issues seen all too often.​ The collar flange on the body is made of a stronger alloy which has been heat treated.  This strengths the collar joint significantly when combined with the adhesive reinforcement. ​ The shaft is made from corrosion resistant steel and the troublesome needle bearing is replaced by a more robust oil-impregnated bronze bushing which eliminates the risk of needle ingestion by the engine.  ​ The steel bracket has been revised to prevent cracking of the co-pilot side skin below it.  ​ The crimped heat duct, known to loosen, has been replaced by a more robust welded assembly which is riveted and bonded to the side skin.​ The original two fuel drain holes have been replaced with four corner drains.  This allows fuel drainage from any attitude on the ground, preventing airbox fires when over-primed.​ Your air filter is held on with screws so there is no need for the troublesome quarter turn fasteners.  Our airbox has integrated nutplates to mount a Backett™ BA5110 filter using its hardware and can mount any other filter with the screws included with the airbox.​ This airbox also features Air Plains improved carburetor heat arm which is manufactured from hardened steel and has a larger bearing area for the clamp; this significantly reduces the wear from the cable clamp.  ​ Our PMA airboxes are designed with weight in mind because we understand that a heavy airbox is a highly stressed airbox.  Rather than using heavy materials such as stainless steel to replace lightweight aluminum components we have made intelligent design decisions such as better distributing loads and reinforcing riveted joints with the addition of adhesive.  This improves the strength of the airbox without adding weight.  The added benefit is that your aircraft does not get heavier!  ​ The result of these improvements is an airbox superior to the factory original which will provide many more years of trouble-free service. Hardware Included: 1X – 649974 – Airbox Carburetor Gasket​ 4X – 1728902-19 - Air Filter Screws For Non-Brackett™ Filters​ 1X - APS0750111-19-1 – Carburetor Heat Cable Clamp Bolt​ 2X – AN916-10L – Carburetor Heat Cable Clamp Washers​ 1X – MS21083N3 – Carburetor Heat Cable Clamp Locknut Installation Instructions and Tips: Download Airbox ICA here Recommended Purchases with this product: 649974 Gasket DP0552130-11 Carurtor Heat Box Induction Seal BA5510 Brackett Air Filter For more information, visit us at Call: 800-752-8481 or (outside the U.S.) +1-620-326-8904 Email:

  • Air Plains Services Introduces New PMA Long Airbox for Stock Cessna 172s

    WELLINGTON, KS (Dec 4, 2023) – Air Plains Services, a world leader in General Aviation engine and avionics upgrades, announced today it has gained FAA approval for a new-manufacture Cessna 172 long airbox designed for a variety of stock OEM engines, adding to the range of PMA airboxes it produces for the 180hp 172XP engine upgrade and for various Cessna 180, 182 and 188 aircraft models. “We’ve been including a new airbox with our 172-180HP engine upgrade package for about 10 years, so it seemed a natural move to develop a similar, improved design for a wider range of 172s that don’t have our upgrade,” said Katie Church, Air Plains president. “Like the other PMA airboxes we produce, we’ve used our years of experience repairing damaged factory airboxes to identify common issues and develope a number of improvements for a stronger unit, at a significantly lower price than the OEM unit.” Improvements for the new 172 PMA long airboxes produced by Air Plains are similar to those developed for the company’s other PMA airboxes and include the addition of structural adhesive reinforcements in areas of high stress, a hardened control arms with a thicker cross-section, and added nut plates to the front of the airbox to accommodate a Brackett air filter, if installed. One of many improvements also includes an additional two fuel drain holes. This allows fuel drainage from any attitude on the ground, preventing airbox fires when over-primed. The airbox also features structural adhesive reinforcement in the highest stress areas, this distributes the stress between the skins and prevents the common cracking and collar separation issues seen all too often. The PMA airboxes were also designed with weight in mind beccause we understand that a heavy airbox is a highly stressed airbox. Rather than using heavy materials such as stainless steel to replace lightweight aluminum components we have made intelligent design decisions such as better distributing loads and reinforcing rivited joints with the addition of adhesive. The result of these improvements is an airbox superior to the factory original which will provide many more years of trouble-free service. The new Air Plains airboxes are PMA replacements for part numbers 0552113-11, 0552113-13 and 0552164-4 on stock engines for Cessna 172I, K, L, M, N and P models and for Reims, France produced 172I, M, N and P models. Air Plains has produced PMA airboxes for its 180hp engine upgrade kit (STC SA4428SW) for 10 years. In early 2020, Air Plains gained PMA to produce replacement airboxes for Cessna 180, 182 and 188 models (part numbers 0750144-1 and 0750144-33). The company also produces PMA airbox replacement accessories such as collars, gaskets and adjustable attachment brackets. Air Plains manufactures and inspects all its parts, including all its airboxes, onsite at the company’s machine shop prior to placing into inventory.
