Sensenich Gets Prop STC For Piper Super Cub


Sensenich Propellers has received a supplemental type certificate (STC) for the installation of its carbon fiber short takeoff and landing (STOL) propeller on Piper Super Cub aircraft. The STC for the two-blade, ground-adjustable prop covers Super Cubs powered by Lycoming O-320 engines. According to the company, the STC is now available and shipment of preordered propellers is underway.

“Extensive testing was performed during the certification project in both Alaska and Texas,” Sensenich said. “Reduced weight, increased responsiveness, and increased operational flexibility are clear benefits of this high-performance propeller. In addition, this propeller’s innovative pitch adjustment feature and stainless steel leading edge protection gives the customer maximum performance in multiple harsh and dynamic operating conditions.”

Pricing will be $6350 for the propeller and $735 for the spinner through the AirVenture Oshkosh fly-in, going up on Aug. 1 to $7250 for the propeller and $785 for the spinner. Sensenich reported that it is also working on projects including FAA approval for carbon fiber ground-adjustable propeller STCs for Lycoming O-320-powered Cessna 172s and propeller type certification for 65- to 140-horsepower four-cylinder Continental and Lycoming engines. Sensenich, which got its start with wooden propellers in the early 1930s, introduced carbon fiber props to its lineup in the late 1990s.

  1. This is a fine example of the type of mod and more rugged and better performing aircraft to soon be eligible for operation by Sport Pilots!
    FAA is expanding Sport Pilot to allow gross weights up to 3,000 pounds, stall speeds up to 54knots, retractable gear, cruise speeds up to 250knots, and use of 4 seat aircraft (with only pilot and 1 pax aboard). The author of “Sport Pilot Encyclopedia” [sold by Aircraft Spruce, etc) has begun advising book purchasers that despite years of interference by industry flacks Dan Johnson and Roy Beisswenger [who were lobbying to add commercial revenue ops of little or no use to everyday sport pilots] on July 24 the FAA will finally publish an NPRM for comments on a new 61.316 with these and other changes expanding Sport Pilot operations that could be effective NLT November 1, 2023.
