 Posted: Sun Aug 03, 2008 5:46 pm Post subject: MT Prop Governor Follow-up Report |
 |
|
A while back I reported an issue with my governor "surging" at certain RPM settings. It would hold 2300 fine but trying 2500 it would jump up to about 2580/2600. After research and a call to Van's it turned out to be a known issue with SOME early revision MT governors. I was referred to MT in Florida, and after a discussion with them, found out that they too also were aware of this. Fix is to pull the governor, send it to them and they will modify it to the "F" level revision. He said that they'd do the modifications and turn it around in 2 days and that it was covered under warranty.
I was a little surprised when I called them back to get a Return Authorization number and found out that they didn't use them... I sent the governor to them insured and with a return receipt on a Thursday. Following Monday I got a call acknowledging receipt with a couple of questions. Wednesday afternoon of that same week I got a call from somebody else at MT asking if UPS ground shipping would be OK!
I returned from OSH today to find my governor waiting for me. Haven't had a chance to put it back on and try it, but here's the work they did per the 8130-3:
- installed new case hardened pilot valve
- installed new conical speeder spring
- installed new flyweight assembly
- installed new cover
- bench tested
The governor's serial number has also been changed to reflect the "F" level revision.
While it was a hassle to pull the governor, I am very happy with the service that MT provided. I would have preferred (I think) an exchange so the plane wasn't down, but this way I get back the same virtually new governor that I started with. Great company to do business with!

I have the same issue with the MT prop governor, it was surging 100 to 200rpm in cruise, and I pulled it off yesterday to send back to MT. A little bit of a hassle when you have the fairings installed. I asked them about exchange and I got the impression that they might be willing to do that but if you send them your current governor, when you receive it back and install it, it will be set at the same max RPM as when you removed it, so you don't have to do all of the adjustments that was required initially.
