More failure trend. This needs attention. That's three in a few weeks.

Default Housing interference

Joel,

Sorry to hear of your issues and damage. Hope you get it resolved and back in air soon as I know your RV10 is utilized frequently.
Question, Do you think it is possible the weights interfered with the housing prior to catastrophic failure? Do you think it is the reason for the weight snapping the ear of the retaining pin because the weights interfered with the housing?

I dont know for sure but there is very little scoring of the case internally so I think it happened when the ear broke. Also every thing abnormal looks "fresh".

Nothing looks like it had been wearing over time.

My governor is the 860-4 mated to an IO 320 with a Hartzel prop. Since I'm at 5 years and the recommended overhaul is 6 years according to the folks at MT I spoke with, I decided to send it for overhaul. At $550, is seems prudent, given recent experiences. It will be interesting if they find anything. I'm sorry you all have gone through the malfunction and resulting troubles but am grateful for you sharing your experiences.

That is considerably less than what I just paid. Who are you using?
In another thread, it was questioned why a perfectly working governor would have a calendar year limit. Many folks are not aware of this,
Or don't care, and run them to TBO, and probably beyond. I chose the rebuild path as you are. Considering the circumstances, Inwould say you are wise to do this.

Outside of this circumstance, there is another option, if your governor is working and you don't have concerns like is being brought up in this thread. You can have an "inspection and re-seal". They replace all of the seals, visually inspect and check for limits. They don't magniflux all of the parts. So, it is a short cut that is about half the cost, but would be better than just letting it go to TBO.

Again, considering these problems, I wouldn't be taking any short cuts.

I called MT directly in Deland. They gave me a quote of $550 for overhaul. I also called American Propeller in Redding, Ca and they were $900+ for the same service..

The manual that Dan provided a link for seems to indicate there is no TBO

The Jihostroj governor is marketed here in the USA by
Aero Technologies, LLC. Aero Technologies, LLC is the FAA/PMA holder of all

their own S-1 design governor for the homebuilt market. The PCU5000 has a large service center network with Propeller and Accessory shops that can sell new or overhaul these governors. New units can be ordered direct, email to: partquote@aircraftpropeller.com, Maciej "Mac" Paszkowski-Sikorski is our sales representative. PCU5000 has been an advertiser on this website for years and continues to support the GA/Homebuilder aircraft community.
