Hi fellow Meyers owners,

My propeller governor is defect. I just get 2550 rpm on static or dynamic take off.

All the other performance data are okay.

I found as an alternative to overhauling the governor is to put a new PCU5000 on the engine.

Any recommendations from y’all?

Thanks and a have great day,

Thomas

Thomas-that looks like a good solution to deal with the older ones we have as they go bad. Any idea how the STC would work?

Hi Ed, do you see the hole in my foot? I almost shot me one…
No STC for our airplanes and no EASA Approval either. I will have to have him overhauled.

Thanks for pointing my nose to this minor bureaucratic problem…

Thomas.

Well, that was not my intent, but glad you did not spend money on something that was not approved.

I saw the note on your exhaust valve. That’s THE reason for borescopes.

Thomas,

I was having the same issue with N430DP this summer. I had it removed and sent to the prop shop for bench testing and had the springs replaced. They ran it for 2 hours on the bench with no issues, but I’m still only reaching 2600 RPM on takeoff.

I have the same problem, but my A&P thinks it is related to the linkage to the governor. Like it is not long enough to get that extra 100 RPM and will need some modification. I am going to address over the winter.

We adjusted low Pitch stop to maximum but no RPM rise. The linkage itself is quite simple to a adjust, but that is not the problem. I will measure the low pitch angle to check for a wear of the propeller. Last overhaul was 2009 and last maintenance was 2020, lubricaction of the hub.

A month before my Mitchell tach showed a malfunction, an overspeed on take off of 2900 rpm without a change in pitch tone. The new tach showed only 2600 and then 2550 on takeoff.
I will keep you posted…

Hello Thomas,

Jamon Pruitt just had his overhauled and might be a good resource for how that went.
