Sensenich said it received a supplemental type certificate, or STC, for a carbon propeller with ground-adjustable pitch. The new prop is designed to enhance the STOL performance of Piper Super Cubs with Lycoming 0-320 engines.

The new prop’s light weight and increased responsiveness contribute to its improved performance on the Super Cub, the company said. The ability to adjust pitch also gives pilots more operational flexibility.

Sensenich said it tested the new propeller extensively in Alaska and Texas during the certification process and said the STC is available, and shipments of pre-ordered propellers have begun. The company said pilots have been “raving” on about the propeller's performance on their airplanes.

Sensenich said it is working on other projects for FAA approval including ground-adjustable carbon props for 0-320-powered Cessna 172s and for other Continental and Lycoming 4-cylinder engines ranging from 65 to 140 horsepower.
