Hey all,
On my RV-10 I've generally had not too bad an experience with
backfire. My engine will almost definitely backfire if I pull
the power all the way off during a descent. You can feel it under
your feet. Yes, the ground lean is set well. I've heard plenty
of planes do the same thing when fully reducing power, so it
didn't suprise me, and it's reproduce-able.
Now with my IO-390 on the RV-14 I experience the same thing.
I did the ground lean setup and if anything I have it even
leaner than the RV-10. But, it does tend to backfire a bit
earlier. I don't need a full power reduction to cause it.
If I just get the power very substantially pulled back, it'll
happen.
Is there anything else I could be missing that I should
be doing if I want to reduce that? I'm guessing if I
were to lean more aggressively that would help. But, I
haven't been leaning it as far lately simply due to the
engine being "new".
Just thought I'd troll for ideas on this one before I
just resign myself to living with it. I *think* I can
even see it on the EGT more on certain cylinders at
times. (i.e. #2 is the most common) It shows up as a
slightly raised EGT due to the fuel burning in the
pipe further down.

I don't know for sure, but I would go full fine on the prop to keep rpm up,
and avoid actually reaching the stop on throttle. I've seen it on the
IO-360-A1A in my Mooney, but only with throttle fully closed.

Short version, there have been three in flight failures of the MT prop govs in
rapid succession, on three different RV10's, the most recent being mine on Sat
the 13th and the previous on the 6th.
I know this is cheeky to say and I apologize to Matt in advance, but full discussion
with pictures of all three events are on TOF (the other forum).
Two failed to high pitch and oversped. Mine went to coarse pitch. Two of the
three actually breached to wall of PG resulting in massive oil leakage that you
wouldn't know about until it is gone.
Several entities working on this. I personally would not fly an aircraft with
this PG until this is resolved.

Question... After reading the threads and noticing the discussion on a SB from
a few years ago, I am wondering... How old or are there any similar dates of manufacture
on these 3?
I have one P-860-3 that was installed in 2005 and has 1200 hrs and there are many
flying from that era and these are the first failures of this type I've heard
of. So either I've been way out of touch (which I don't think it is as I communicate
with many on things like this) or there is some other piece of info
missing that may be common to the situation. If they were all of newer vintage
perhaps that would explain it?

Tim, my MT governor failed right out of the box. The bushing seized almost
instantly where the drive shaft exited the housing, which caused a prop over
speed, and ruined the crankshaft of my IO-540. My MT governor was listed on
SB#27 which unfortunately I didn't know about. 3 months and $10K later I've
started test flying again. Not happy to say the least.....

Good question Tim.
Mine carries 10/11 on the sticker and 9/11 on the data plate. These were actually
manufactured by an entity with an unpronouncable name starting with J that
makes for different brands.
According to MT-USA today, the SB only applies to units that carry 2012/2013 dates.
They checked mine this afternoon and said it was outside of the SB.

Mine was manufactured in mid 2012 and purchased directly from MT in
Germany. It is currently in route to MT in Florida to have the SB performed
as well as thoroughly inspected.

That's basically pointing in the direction I was thinking. Yours was a low-time
failure and manufactured fairly recently. Rick's was the same. I don't know
what Todd's story was on time but I don't think he has as much time as many
do. So if these were manufactured more recently maybe that's the common issue.
There were many P-860-3's sold... Mine being installed in 2005, but it's only
recently that these came up. So there may be a difference in materials for
the vintage or something. Very interesting though.

I'm in the same manufacturing date for P-860-3 as Tim -- 2005. And so far, nary
a glitch with it (knock on wood). Like Tim, flying since 2006, but not as many
hours as Tim.

Makes me wonder...I am on road with plane right now. My governor came
direct ship from Germany and is the -5 variant specified for the wide deck
engines, not the -3 that Vans sells. My prop was assembled by MT in FL and
shipped direct to me. Have 700 mi flight tomorrow to get home. Guess will
have to plan route to avoid over the water and desolate stretches.

Kelly - The folk who experienced the failure said they felt like 10 min of t
ime before becoming a glider was about what they experienced.
Might be worth carrying a tad bit more oil in the sump while this gets figur
ed out.
Checked my -3 and it's 1/11 date. (9 months before one of the failed gov's
) My fingers are crossed that they can get this figured it soon since I shou
ld be flying fairly soon.

I suspect extra oil might only get you and extra minute, and might get on

Basically I was just saying that I wouldn't knowingly be running it on the l
ower end.. If carry as much as possible without giving it so much that it w
ould blow out.
I should have mentioned that 90 kts was the limp-along speed reported withou
t over speeding (again).
The over speeding has occurred in 2 of the 3. Both of those props became d
ecorations and the engine cases split for inspection. (I believe 1 owner f
ound it was cheaper/better to buy a new IO-540 than to repair the existing o
ne. That's 2nd hand knowledge from a reasonably good source though, so don
't hold me to it if it's wrong.)

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.
