Maybe you could just trim the other side to match.

Friend of mine got caught in the departure line at AV when the Breezy crashed and closed the airport for a few hours. Everyone in line just shut down and sat next to their planes. He said he noticed a guy off in the grass just off the taxiway working on his prop and being bored, walked over to talk to him. He was hacking off the tip of his Prince P-tip with a hacksaw. Seems he had an incident taxiing through the rough and wacked off the other tip. Was just "adjusting" it so he could fly home. The guy didn't want to talk much to my friend and so he just returned to his plane shaking his head.

Update guys, prop can't be repaired. The crack is to big they say. So I have to order a new one which will take 6 weeks. Crap!! John

Yeah give Lonnie Prince a call. He probably won't be any quicker than 6 weeks unless he has a cancelled order waiting for sale. His lead times recently have been longer than 2x 6 weeks...do the math, not trying to bad mouth him, his props are beautiful but woefully off of promised delivery dates.

Hey guys, would going to a Prince prop be an easy swap? I am new at this.
Also which would be better elliptical or p-tip?

Switching from one brand of prop to another is a very simple job in execution. The hub thickness may be slightly different so you may need a different length of AN-5 bolts for a Prince but otherwise it's pretty simple. Logic would say to contact your local FSDO and ask if going from one brand prop to another (same size and pitch) would be a "major change" and if they feel it is, you'll need to go back into Phase 1 for at least 5 hours. Some FSDO's will require it, some will say it's not a "major change."

With regards to the different models of prop Lonnie sells...I think most AeroVee owners are happy with the P-Tip prop given its ability to "flex" at high power settings and low speeds (i.e., climb) so you can get more climb rate without sacrificing cruise speed. On the other hand, I believe the elliptical is perhaps a little faster and also less expensive. It doesn't have the "flex" the P-Tip has though. I'd call Lonnie and talk to him about it. He's a great guy to work with!

Whatever the response is from the FSDO, get it in writing, or at least an email. Something more than just a verbal "OK", especially if they say it's not a major change. You may run into an inspector with a different opinion someday down the line, and you'll want evidence that you checked and got an "official" answer from the FAA. The old "better to ask forgiveness than permission" does not work with the FAA.

Help me out here, how does the FAA know which prop my plane is supposed to have? Its been a few years since my AW, but I don't remember specifying the model and serial number of the prop on the form, maybe I did. How does one specify it if they built the prop themselves?
