    Owner produced needs to conform to an approved design. If there is no approved design, you don’t have an owner produced part, you have research and development and that falls under Experimental!

    The PA-22 and PA-200 TCDS both specify a fixed pitch metal propeller with a Lycoming O-320.

    The only engine option that allows for a wooden prop is the Lycoming O-290 and that is limited to a maximum diameter of not over 74 inches.

    The only way I can see for a 80" wood prop on an O-320 would be via STC. Unfortunately.

    Props, at least older designs are designed and manufactured to CAR 14, not CAR 4. The PA-20 and PA-22 series are CAR 3 airplanes, so prop installation would be CAR 3.

    Any updates on this prop? Eddie Trimmer’s website still says the STC is only for the O-360. Can ayone confirm if he’s been able to add the O-320? Performance update?

    Airframes Alaska (the Bushwheel guys) are selling the wood Sensenich for O-320 powered super cubs. They might be able to help you find an STC or Field Approval.

    I do have to say though that I am not overly impressed with the one hanging off my O-360. I intend to borrow a couple of props to make some comparisons at some point. I'll be able to make a better opinion of this prop after I do that.

    Thanks for the info. If you do the comparisons, I would like to hear what you find out. I have the old "club" prop on the O-360, and it would be nice to lose those LBS off the nose. But I would want to know I'm replacing it with something better!
