So what is the difference between the certified and experimental prop, besides the sticker that says FAA approved?
Paperwork
Steve, do you know if approval is being pursued for installation on a 150 hp PA-12 for this ground adjustable prop or only PA-18 at this time? Thanks
PA18 with 150 and 160 hp O-320. The prop will then be Type Certified which will make it easier for others to get STCs for other aircraft. There have been DER approvals on O-360 powered Cessnas based on the data from the PA18 180 hp STC.
The flight test engineer that was here was on the committee that wrote that. He interpreted it differently than it was sold to us. He is right at home with the FAA.I sure wouldn’t want to be the DER that approved that. The PA-18 STC is an airframe STC based on the “new” Part 23. The approval is based on the airplane being a “Level 1” airplane, defined as having 0 to 1 passenger seats. The engineering rigor for a Level 1 is much less than for a higher level. FAA changed the certification rules based on “risk to the public”, so less seats is less risk. That’s part of the reason Sensenich changed gears and is now working on getting a TC for the prop. That opens up the availability to aircraft with more than 2 seats.

No idea, waiting on the FAA. Will updater this thread as things move along.

Props are being built, and should be sent out fast after the rubber stamp.
The DER has an amazing reputation.
