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-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…

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.

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…

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

Update: had another cylinder overhauled and all rotocaps replaced. On Runup the fuelflow was well below spec. Had the fuel control unit overhauled here in Germany. Came back with factory settings. On run-up engine stalls below 1500 rpm. Need to setup the FCU according to SB. Did anybody venture this way before and has some knowledge to share?
I Miss flying the Meyers…

Thomas-My understanding is the fuel flow set-up is not overly complex for the person who understands it and has done it. Who in Germany have you used in the past? Wonder if you might find a YouTube that might show it?
One thing to make sure is that you adjust your fuel flow at wide open throttle at sea level to be 10% of your rated HP. So on my IO-520 rated at 285 HP, my fuel flow at takeoff is 28+ GPH. That ensures keeping CHT’s reasonable on climb out.

Update: some tweaking of the idle mixture and the engine runs fine. Take off fuel flow ist 28,3 gal/h resulting in good temperatures and performance „as expected“ by us. Annual done and the weather is also improving.
Keep on flying them birds!

Excellent!! Very glad to hear. I am dealing with a gear door issue that hopefully is resolved tomorrow. 73’F in NC today. A big fake…February 17, 2023 at 2:21 am #2581

Even bigger fake on WX. Going to be 84’F in NC on Thursday. Tress and plants ae very confused.
My gear door issue was satisfactorily resolved and they were also able to re-weld the wind walk support on the wing inside of the flap. I dare say a lot of our fleet has busted wing walk supports. I don’t think it is an AW issue, but more of a PITA and something you need to deal with. A sign will be some flexing and creaking when you get on the walk, especially to clean the windshield.
