Propellers - Overhaul or IRAN?

[edasmus]

I had a very good experience a year ago with H&S Propeller in White Lake, MI. They overhauled my rear prop of my 1973 C337G. I had a not good experience with Aircraft Propeller north of Chicago the year before and ended up buying a brand new front prop.

Not all shops are willing to do IRAN’s or reseal. I had one shop that required overhaul on any prop that was beyond 10 years since last overhaul. Based on my experience with H&S, I would start there. They seemed quite reasonable and demonstrated a desire to keep old equipment airworthy if at all possible. Good luck! 😊

My front was OH in 2011, and the rear IRAN.

Still very low time in hours.

So obviously in 2011 the parts required for overhaul, were available, ...but may not be now?

Any clues gents?

I recently had my front prop overhauled by H&S as well. Haven't flown it yet but a generally good experience.

The issue with threaded props is that once you pull them apart, you can't put the ferrules back in the same place. So you usually have to find used ones from another prop that was dismantled similarly. And that's getting very difficult to do. H&S had a hell of a time, delaying the overhaul by a few months. If you're interested, I might sell the pair of mine as I've been looking for an excuse to spend otherwise perfectly good money on 3-blade composite props. My marriage is apparently going too well, so...

In Canada for private ops, we are required to overhaul every 10 years of calendar time, regardless of airtime or manufacturer's TBO.

I had my front prop done last winter by BL Aviation outside of Montreal. Great service, final invoice was as quoted.

Rear prop is due next year - will likely go with BL again.

Okay, I will bite.

How much for a pair of spare ready-to-re-use ferrules?
