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.”
