Many prop shops will not recertify a polished prop unless it is repainted.

Nothing had been said about spinners as far as I know.

I understand the only legal polished prop is a Hamilton Standard.

I have been told this also. As long as the prop manufacturer has a procedure for polishing it is approved. Ham Standard does.

I am restoring a Stinson 108 right now. The previous owner had it parked down at Oakland International and a Fed ramp checked the airplane and red tagged it on the spot because his prop was polished.

Not very nice! :x

Thank goodness for the FAA. How would we survive with out them?

That's the info I was looking for.

Thanks Rob

I read a letter for McCauley, i think, and the issue was corrosion resistance. I have never heard of the load path issue before but...

Story I heard is that you change the stress levels when you change the surface of a stressed member. Makes about as much sense as corrosion though. How much corrosion can you have on a polished surface?
Some of these people think we fly space shuttles or something, where little dents or scratches can really be a problem. If these people saw an average AG plane they would have a fit.
