propeller governors

[Learjetter]

Just a quick thread update: I called several prop governor overhaul shops today to get quick quote ideas on cost and lead-time. Here's what I found out:

Supposedly, I have McCauley CF310D1/T1 or CF310D2/T1 governors (per the TDCS) with prop sync, and these are "old numbers", and the numbers are hard to look up and get good quotes, so take everything here with a grain of salt.

My logs say front gov was OH in 1999, the rear gov in 2012. OH engines went on in 2014 and 2018, and MT props in 2014, but no mention of governor OH at the time either the engines or props were installed.

McCauley recommends 5 years or 1800 hours TBO.

My symptoms include "slower than I'm happy with" responses on the feather check, and a little 20-40 RPM "hunting" in climb/cruise.

H&S propeller shop: $1050 each with a 10 day turnaround. Yes, he quoted me $1050 each, but I think I'd expect something closer to $1500 based on previous posts in this thread.

Tiffin Aire: $1500 each with a 5-7 day turnaround

Quality Aircraft Accessories (QAA): : $1520 each and 10-12 day turnaround

Aircraft Accessories of Oklahoma: $1600 each and 30 day turnaround (or $+175 AOG fee to jump to head of the line).

Based on this small survey, H&S is the winner in 2023. Are there any other shops you've used and can recommend?

As a follow up, H&S did my governor overhaul in March and it came in at $1100 which is right about what they told me it would be (mine is a Woodward). However, I was also told about a week turnaround time but in reality it was a month. So I think they are pretty good on the pricing, but the timing ends up being longer than anticipated. They do all my propeller work and I will continue to use them as they have always done a fine job.

During my engine rebuild, NO ONE has been even close to meeting the schedule they originally noted, so H&S isnt any different than anyone else out there in the aviation arena. I just think that is the way it goes and we have to expect delays in lead-times.

I sent mine to a Prop shop in California, but can't remember the their name. I can check my logs tomorrow, if needed. They charged $1500 and $1700 due to extra parts required. The governors are the accumulator type. I also sent them my non-accumulator type I think the price was about the same. Return around was about a week.
