I need to correct this, MT Germany did ONLY ask for the serial numbers
not what type of engine!
I try tomorrow to find out more abot what is behind but you can imagine
they are busy....

They did ask the engine type and as I have two governors from them one
on a O-320 and the 2nd for an IO-540 I got only feedback by email so
far (still need to supply the O-320 serial which is at the airport).

OK. Will have to see what the bulletin says, as I have 860-5 mfd 06/13.

told me. In certain situations, the fly weights can become loose and
cause the failures that we have seen. They have already identified the
modifications needed and will be publishing SB 31 this coming Monday.
All 860-3 governors manufactured between April 2010 and July 2013 are
affected regardless of the type of engine.
I did encourage him to post something so that they could get ahead of
the issue.
By the way, my governor is in that range.

Kelly,
I'm just passing along what MT in Florida told me. They have my
governor in their shop and told me they have the parts on order from
Germany to correct the issue. Beyond that, I don't know what the
specific issue was other than they said it only affects non
certified IO-540s.
I really wish someone from MT would at least get out in front of
this and post something.

I might see higher compression pistons affecting the prop via
harmonics. I do not see what else about the engines would have
anything to do with who put them together. For the most part,
engines built by the reputable shops mentioned will have flow
balanced cylinders, well balanced rotating parts and run
smoother than a factory engine. I see nothing about that has
anything to do with the governor. So far we are not getting any
information beyond the service bulletin about where the problem
might lie.

Werner,
What engine do you have?
I have an Aerosport Power IO-540 with 9.2:1 pistons and MT
is telling me
that mine is impacted as well. From talking with MT in
Florida, the
engine is what is driving the modification requirements. Ie
Barret,
Aerosport etc....
Is this what others are hearing as well?

I got this morning a feedback from MT, that my Governor with
S/N 10G598G
is impacted and that I should send it to the factory to
be fixed
(this is manufactured in 2010

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?

I'm thinking that most of them were delivered
around the

related to some
issue that came around that timeframe. I bet
the SB serial
number range
is insufficient.
Because there are so many MT governors flying
since 2005
that we would
hear of more if there were a large number of
failures. That
said, if
your governor was from 2011 thru 2013, I'd be
concerned even
if your
governor isn't within the S/N range.
