| Subject: | Re: MT P860-3 Prop Gov fail. |
Guys my governor chewed itself up internally, the bushing spun on the drive
shaft, which opened up a misshaped hole in the housing, which allowed the
gears inside to scallop and gouge the inside. The unit was tested and had
more than 50% leakage, ie it wasn't putting out enough pressure to operate
the prop blades. Unfortunately from the onset there was no indication of a
problem other than the over speed, which I eventually adjusted out by moving
the arm on the splined shaft. Had I not taken the governor off and tested
it, I would have probably kept flying. Since it happened on the very first
flight of my -10, I had no reason to suspect anything was amiss.
Of course MT is bearing no responsibility from the emails I've seen so
far.......

One thing that I will add is that I get what experimental aviation is all
about and that we exist and are successful because we all absorb liability
for own misfortunes.
However, this is a now at least a three peat failure of a CERTIFIED part,
each one of which sold carried a chunk of liability insurance cost for just
these types of failures that we paid for ourselves in the purchase cost.
I'm not looking for anything other than being made whole and for preventing
something like this from happening in the future with, God forbid, less
fortunate results.

I've checked the plate on my MT860-3 manufactured in 11/10 but it says
made by Avia-Propeller not by Jihostroj.
It looks as well a tad different then the one on the pictures from Myron.

Ctoday's adventures.
1. There are now four confirmed failures. Details on the fourth are forthcoming,
but apparently happened on first flight. My flight time was 235 hours, I believe
one other was 140ish and another over 1000.
2. Of the three previously known and described here, all three units were shipped
by Van's in a five month span of late 1011/early 2012.
3. Alan Barrett gave me a list of things to do to check my engine. Unfortunately,
we found significant metal in the finger filter and the main oil filter media.
There was only about 12 hours on the oil since last check which was clean.
4. Hartzell said that since mine over torqued instead of oversped, the prop wasn't
necessarily toast but because of metal in oil, the prop would need to be torn
down and serviced. Hartzell was already fully aware of the situation when
I called them.
5: Obviously all red arrows point to MT, with Van's, Lycoming, Hartzell, and BPE
being coincidences. (So far). The MT-USA office keeps pointing to the German
office which I have yet to talk to because they close at 8:00 am Pacific time
and are on some kind of holiday as well.
6. My insurance is AIG with Gallagher. They were very up to date on the issue before
I called and are trying to be helpful. They are working with at least one
of the other parties as well. An AIG adjuster is meeting with me at the hangar
tomorrow.

Hi all, so here is the rest of my storey.
All in all not too impressive. This happened on April 27, 2016, during my
very first flight. Engine over speed to 3060 rpm, which heated the
crankshaft thrust surface and caused multiple heat checks. Unfortunately I
didn't respond as quickly as I could have so the crank was destroyed (first
flight, just coming off the runway, not expecting this etc). Engine was
torn apart, none destructive tested and crank shaft was replaced.
Here are a few picture of what my governor looked like internally.
#2083 shows the bushing that was seized, #2084 shows some of the gouging,
#2089 shows the make, serial # etc, #2092 shows where the bushing should
have been, there were sharp ridges etc from the bushing rotating in the
housing, #2095 show one side of the area where the gears were located,
#2096 shows the same area, opposite side, as does #2098, #2082 shows the
house where the drive shaft passed through to the engine drive and where the
bushing used to be located.

You are right under me on the SB list. I feel EXTREMELY lucky nothing has
happened in my 135 hours of flight. I am really at a loss as to how to
proceed here. MT has my governor for the SB, but I wonder if I shouldn't
just bite the bullet and go to a different brand.
Is there a better mouse trap out there? I'm not sure if it matters, but I
have an MT 12B prop.
Thanks,

I'm curious as to whether Rick's failure is related to the failures of
Myron and Todd. It seems to me that Rick's failure is directly related to
the published SB (Matching SN and bearing issue). Myron and Todd's both
has SN's outside the SB and experienced broken metal as opposed to a
rotating bushing.
It seems to me like Ricks failure, while very significant, expensive,
noteworthy, and concerning, is unrelated to the recent failures....
Am I right?

Hi all, looks like I messed up the attached pictures. I'll try again.
Here are a few pictures of what my governor looked like internally. #2083
shows the bushing that was seized, #2084 shows some of the gouging, #2089
shows the make, serial # etc, #2092 shows where the bushing should have
been, there were sharp ridges etc from the bushing rotating in the housing.
I will send the other half separately.

Here's the rest of the pictures.
I must point out I had to take my governor to Ohio as there are no repair
facilities in Canada for MT governors. I took it to Tiffin Aire (Tiffin,
OH). Mike Baird the manager I dealt with was very good to me and certainly
helped secure a brand new replacement governor from MT for me. I did end
up paying $340 USD for duty, shipping etc.

Phil you are correct, it is a different failure. The one fact I wonder
about is whether Myron and Todd failures somehow started with the
bushing? Does anyone know?
Unfortunately I can=99t figure out how to post any pictures on
Matronics. Anyone know how?

I'm thinking that most of them were delivered around the same timeframe and t
hey are probably just differing failures but still related to some issue tha
t came around that timeframe. I bet the SB serial number range is insuffici
ent.
Because there are so many MT governors flying since 2005 that we would hear o
f more if there were a large number of failures. That said, if your governo
r was from 2011 thru 2013, I'd be concerned even if your governor isn't with
in the S/N range.

Well, I have pretty much the same governor and prop. My governor is a
-5, which came direct from MT in Germany, but that may or may not be a
difference. I have the same MT 3 blade prop Vans sells.
I made some minor modifications to my flight today with these issues in
mind...to minimize time over water, away from roads or civilization, but
mad 4.5 hour flight to get myself and plane home. Where to go from here
will depend a lot on the reports. No one wants to do a teardown, or have
a lot of expenses not covered by insurance. Nor do we want to have
hangar queens awaiting a solution.
I have to look up the service bulletin and see if my governor falls in
that range. Has anyone posted the service bulletin?

Thanks Phil. I sure thought you would be flying before I first got into

I was thinking we'd be up about the same time.
I got stuck communing 3.5 hours each way to work on the plane and I did it every
single week for a year and a half. That really slowed me down.
Last December I finally got a hangar in Waco and could finally move the plane
up here with us. Now it's just a 10 minute walk from the house to the airport.
It's within striking distance to flying (I think).

I had just this morning an email feedback from MT Germany, they are
working on a new SB which should cover the impacted serial numbers so
they now seem to be aware of what is causing this issue?
