N95598 gets a new prop (reconditioned like new)

Re: N95598 gets a new prop (reconditioned like new)

Hank,
Any mechanical means of removing the existing finish can compromise the blade symmetry and airfoil profiles. For this reason, the FAA only allows very minor prop maintenance tasks to be performed by A&P. This prop was re-conditioned by an FAA approved repair station. They have the data and tooling necessary to re-finish, re-pitch, balance, and verify airfoil profiles. The finish is anodizing, which requires surface preparation that is normally only authorized under repair stations. On this particular prop, you can see that the anodize job left a diagonal line across the hub. I assume this is because they did only one blade at a time in the plating vat. As best I can determine, this is cosmetic only and does not affect the integrity of the prop. The logbook has a return-to-service approval by the repair station, so I am pleased. I am not saying that an owner or A&P could not refinish a metal prop. But if you do, just be aware of the FAA requirements and study up on the important issues. Even the simple task of painting the tips has some implications on balancing. I intend to check this and use black paint on the blade backside to fine-tune the balance. Look up the manuals published by Sensenich on their website for some good maintenance information.

My 45 prop was polished at one time but is dull and nasty looking now from years of storage. Any idea what is needed to bring it back to look so nice? I have heard owners are NOT supposed to polish props (from the same ramp rats who give all kinds of bad advice). I actually kind of like the painted prop like yours.
What's the straight skinny on refinishing metal props?

Hey Terry,
Does look about like a new prop-Really going to be a nice finishing touch on the T/Craft.

Terry, it looks great! I had a 7445 on my BC-12 (and will again if I ever finish the restoration) and though it flew great most of the time, it would have been nice to have a 7443 in the summer time!

The tips and stickers turned out great! Why isn't that thing on the Taylorcraft yet?

This morning painted the tips on my new (well like new) McCauley 1A90/CF7443 propeller. Getting closer to having N95598 back in the air.... thanks to a really great barter/trade with AJ Frisby.
