Prop replacement (Aztec)
I heard today that one of the props on the Aztec was found at Notice 75 to be "scrap". It's the CSU unit itself, rather than the blades, that is apparently beyond repair.
Before I just toddle out and buy another one, is this an opportunity to replace both props with quiet ones? Are there any quiet props certified for the Aztec E?
What will it cost? How long will it take? Are there any disadvantages?
Your urgent answers will be appreciated as I have to get the old girl airworthy in the next couple of weeks.

Don't know about 3-bladers for the Aztec, but we had a new CSU fitted to our existing blades a few years ago and it was a LOT cheaper than an all-new prop. I expected the blades to be "scrap" at the next Not75, but they weren't. The new CSU now has about 700 hours on it and we're still on the same blades etc.

I think that there is a mis-understanding here the CSU is bolted to the engine not the prop and is NOT subject to the notice 75 check.
Keef you could not have had a CSU fitted to your blades , I think that you mean that you had a new prop hub.
It should be no problem to get an OHC CSU try .

Hi Timothy,
I had a quick look a the websites for the three most likely contenders (McCauley, Hartzell and MT) but none seemed to be offering anything exciting for the Aztec.
There is a guy on the piper owner site, looking to see if people are interested in an upgrade with the more powerful Navajo engines and matching three bladers.

Thank you all.
I am particularly interested in A & C's point.
If the CSU does not go to the prop shop, how could the prop shop tell me that the CSU was beyond repair?

I would agree with A & C here.All the CSU's I have had any thing to do with are fitted to the engine.I have never worked on an Aztec mind you.Have another word with the prop shop doing the notice 75.As for a three bladed prop your best bett is to e mail the likes of McCauley and Hartzell and ask them if they have a three bladed prop with an STC for your aircraft.

My mistake, it was the hub all along.
A reconditioned hub is £1600
Better than a new prop at £6,000 mind you
So, the cost does not justify moving to quiet props, but thank you all for your help.
