Just had this go round at Ryan. The argument is that the hypothetical
prop was manufactured, alodined and painted. Some FSDO's consider the prop to no longer comply with the TC when stripped and polished. My friend (an A&P) contacted Sensenich about his polished prop. He asked them if polishing it affected its airworthiness. They said no. He asked them to put that in writing. They declined. His prop went to the prop shop and returned painted. -- Kevin McCue KRYN '47 Luscombe 8E Rans S-17 (for sale) -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =-----

Is polishing your prop legal?
Probably not. See http://www.aopa.org/whatsnew/newsite...03-3-140x.html Dang. And we just finished it today. It took two days of stripping, Scotch Guarding, wet sanding with 220, then 400, then 600, and a whole bunch of Simichrome and Mother's polish -- but it looks fabulous! Guess I'll have to ground myself now...  -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination"

Ha! Yeah, I had it pressed and steam-cleaned, too... Sheesh. My hands are so sore from sanding, Scotch Guarding would probably do them good. How the hell do people strip planes for a living? And how do people keep bare aluminum planes shiny? Speaking of which, why is THAT legal, if a polished prop isn't? Weren't those planes "painted at the factory", and now they don't have sufficient "anti-corrosion protection"? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination"

Actually, I believe most of the shiny, polished, bare aluminum planes I've seen were not painted at the factory.

Welp, 2025 alloy and 7075 alloy, two of the alloys of aluminum props, develop intergranular corrosion and die if the passivating layer of chromic acid conversion and paint are not left on the prop. But I guess if it is polished every day . . .

Paint is an option.

It's legal, but mama said it would make me go blind.

Now that we've got ours almost done, of course one of our airport wags mentioned that it might not be acceptable -- despite the fact that every 10th plane you see has one. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination"
