Thanks for the update on that Tim, I've not seen that posting strange
but I know now.
I guess there will then be an SB update on that.
Cheers Werner

Hello Werner
If you decide to order the parts for this SB, count with1 set for me.

I sent email request to Van's support late Friday and had reply
yesterday morning. Parts are being supplied free.
Just contact them with your builder number.

Hello Carlos,
I'm afraid to late Michael did order for all 4 Swiss (at least what
we've discussed) but it's easy, you call Van's have your serial handy
and tell the status of your engine mount.
Are you in Bracciano for the EFLEVA meeting?
Cheers Werner

Sorry Carlos the order was sent already to Vans. I wasn't aware that you need this. Please send me your details and I can include you in my RV-10 distribution list going forward.
To all I think it's more helpful to report cycles from grass rather then flight hours.
Kind regards
Michael

Scott,
I agree with Vic.
My concern is as the elastomer donuts contract, space develops between
the donuts and the weldment when it is unloaded in flight. I have had
this happen twice in 300 hours, and had to insert shims to remedy. You
can here it rattle during taxi. When this occurs, my concern is that the
edges of the new plate insert will rub on the 4 tubes going into the
current bracket. We can see this as currently evidenced by the elastomer
metal washer today. I do agree that adhesive in between the new plate
and the old one may not be the right answer, but using a thin enough
layer might prevent this situation from occurring I don't have the
answer other than to weld the new reinforcement plate even on the
non-cracking mounts.
Did engineering look at this situation Scott?

I completed the no-crack SB on my RV-10 this morning. I painted the
plate yesterday and let it dry over night. This morning I put a small
ring of red RTV on the plate half way between the inner circle and the
outer edge. I stuck this into position to ensure the plate doesn't come
close to any of the engine mount tubes at the corners. Then I lowered
the airplane and a little of the pro seal squeeze out the side. Cleaned
that up and then install the top cap with a single washer spacer.
I like Vic told Van's that it needs some way to stop the plate from
vibrating around and destroying the engine mount tube and they agreed,
but didn't really suggest anything.
Thanks

Yes, it was looked at.
That is why my previous post mentioned

Yes, it will take some effort on owners part to occasionally check for
loss of preload in the nose gear elastomers. It has always been a design
intent that there not be play in this location. It is in fact possible
that some level of play can have contributed to damage in some cases.
N410RV went almost 2000 hrs using the originally installed elastomers,
but it did require some periodic adjustment by adding an additional
spacer washer.
The need for that periodic check should probably have been better
conveyed to those with flying RV-10's. As a result of the continued
airworthiness program for the RV-12, I think we are beginning to do a
better job with that type of thing.

Actually Van's didn't agree, which is why the NOTIFICATION was issued
without that recommendation.
Since you used some RTV (or proseal? you mention both...), report back
at your next inspection and let me know if it is still holding the plate
in place or not.

All went together really well. The aviation welder did a beautiful job.
Fixed a cracked step too!
I forgot pics today but I will be zip tie crazy in the morning tethering
all the wires, and I will take some then.
Only problem has been the extra nose height gained from new rubbers, new
nose wheel tyre (higher quality one is bigger in diameter) and the extra
thickness has dropped outré tail down. The Comanche now will not pass
its stabilator under our tail.
Ohh well……time to fix that problem. But it is a good problem to have.
Total man hours to date;
Strip down and have ready for welding 10 hrs.
Welding repairs 4-5 hrs approx.
Reassemble 9 hrs.
Tidy up and re cowl and paper work estimate 3-4 hrs.
All up about 27-28 hours I guess.
The fix with the spacer ring looks really solid. I assume that the
doubler insertion actually achieves the same result.

Default Nose sits higher
Yes, I noticed that the nose sits a little more proud now. I measured it
at about a 1" gain. Mine has both the new plate and the doubler. I
noticed it as well when I was cleaning the vertical fin, as I could
reach up quite a bit higher.
And it sounds much more solid when taxiing now, too.
Scott, I did religiously make certain the elastomers were tight. I had 4
of the washers in mine. I see now that the service bulletin recommends
replacement when 3 are needed.

I think the recommendation is to replace if you need MORE than 3.

I did my SB work this weekend. I ended up using a thin layer of RTV but
did it over the entire surface, and then jacked the back end up so
squeeze everything out that I could. In the end, there is really almost
zero gap between the 2 plates, and there shouldn't easily be any
moisture that gets in there.
I believe the SB should prevent much worry about that particular part
breaking, but I do have one area of concern that will linger.
The shaft that the elastomers ride on, directly contacts the hole in the
engine mount. The doubler is slightly larger, so there won't be an issue
with that.
But, when you look at the shaft, right at the top of the topmost
elastomer, one side of my shaft was chafing on the hole of the engine
mount. This led to a slight thinning of the shaft in one area. One other
thing I noticed is that the shaft had a bit of rust inside.
I believe that: 1) people should prime (NOT liquid plumber, but liquid
PRIMER) the inside of that shaft before initial assembly.
2) That shaft won't last forever. At 1070 hours, it's showing wear. I'm
sure it'll go 2000 hours. But, since this thing was designed with no
replaceable wear surfaces, it won't last forever. I would love to see a
sleeve over that part of the shaft, that can be replaced, but doing so
would require that the elastomers were made with a larger hole, and the
tophat shaped retainer would have to be wider too. So this isn't likely
to be an easy thing to fix. So, I think people are going to have to pull
that shaft and inspect it (I'd recommend maybe a 500hour inspection at
least) and replace as necessary. On Van's end, I'd hope that they keep a
dozen of these in stock, because it's going to be considered a wear part
on higher time RV-10's. I don't know what that part costs, but it would
be nice if there was some sort of bushing there to protect it...either
on the hole side, or the shaft side, that could be replaced.
Maybe Planearound should re-engineer for a bushing.

Two thoughts
1. With the WD-1001K-MOD doubler installed it looks like there will be more clearence so the metal plates of the elastomers may clear the support tubes
2. With the added thickness of the doubler, you may need fewer U-1002 washers to take up the slack. I wonder if three washers will still be the max allowed

Having owned a Mooney for 16 yrs with the exact same shock disks as those on the nose of the RV-10,
I am a bit surprised that they would lose that much height. They are installed with more compression on the Mooney, requiring sizable tools to compress, they only lose height on the newer, heavier models. My E model is about 1645 lbs empty with 2575 gross. It uses 4 disks on the mains and 3 on the nose. After 14 yrs they still meet spec for tension, with no added spacers. Perhaps the RV could use more compression...........

I found no cracks, and ordered the WD-1001K-MOD today from Van. They told me that it was backordered, so it will be a few weeks. I don't plan on installing it until my next Condition.

I'm not flying yet so if someone needs one (and I'm not on the backorder

it out.

I requested mine last week, got it today. If someone is AOG and really
needs it, could forward. Planning on painting this pm and mount in the
next day or two.
