| Subject: | Re: Cowl Fasteners |
I have 2000 plus hours on my RV8 with the Skybolt cam lock fasteners and a
Sam James Cowl.and ;plenum. There is nothing better. Cowl can be removed
and reinstalled in 2 to 3 minutes. Nothing comes loose and no ratteling.
I
never hesitate to remove and check engine etc. because of the ease of
removing and reinstalling.

Here's a spreadsheet with settings from my AFS engine monitor. It's a
little hard to read at first but you'll get the idea.
These aren't the strict limits set by Lycoming. I've massaged them a
bit after living with the plane for a while. For example, if you set
the RPM limit at 2700, you'll get a nuisance warning at 2710 so I
bumped that up a bit.

| Subject: | Tailcone crack found per SB 08-6-1 |
I found a crack in my tailcone as described by the SB during this year's annual.
I've got 775 hours on the Hobbs. It's been flying for 3 1/2 years.
I've only done stalls a couple times, i.e., Phase 1 and BFRs.
However, the first time I landed with a significantly aft CG it wasn't
pretty. I banged the tail tie-down hard enough to bend the "open
loop" eye bolt and grind half an inch off the rudder cap. That was in
December 2008. I think that event may have led to the crack.
I've been checking it visually at every annual and whenever I have the
panels off at the elevator bellcrank.
At some point during the previous inspections I saw what looked like a
minor wave in the bulkhead and a fine line where there is now
definitely a crack. When I first saw it, I crawled into the tailcone
and was able to feel the area with my fingernail. After first
noticing the "fine line", I watched it very closely at every
inspection. I never noted any change over the next two inspections.
This year it looked more pronounced so I looked even closer. I've
been working as an IA for 20+ years and I've seen a lot of cracks.
Even with my hand on it and solid boroscope inspections, I could not
convince myself that the mark was a crack. We finally confirmed it by
shining a bright light from the front of the bulkhead and looking in
from behind with a boroscope. After disassembly I centerpunched the
outboard rivet at the top of the bulkhead and the crack really jumped
out. Before that, even with the top plate removed and having complete
access to the bulkhead, it was hard to definitively call it a crack.
The repair is pretty straight-forward. The only comment I would make
is to completely remove F-1010A in Step 9. It's only three more rivet
heads and it makes working in the area a lot easier since you can
drive the tails out of F-1010A on the bench instead of with it
attached to the bulkhead.
In the future I plan to treat any warping or marks on the bulkhead as
reasons to add the doublers. The damage seems to have happened
slowly, not suddenly, so the 25 hour inspections seem adequate to
catch the problem. You can see the area through the elevator
bellcrank covers with a bright light, so the inspection shouldn't add
more than few minutes to a preflight.
Last week we inspected another -10 for a customer and there were
definitely no cracks, lines, warping, etc. It just looked completely
different.
I'll post another picture with the doublers installed and the total
time to complete the repair.

Well, I guess that proves that the S.B. was a valid one
and should be done. I know lots of people were
doubtful, but now that there is another case it's clear
that it's a good idea to do. It was a 1 day job to do
the whole thing, so in the big scheme of things it
wasn't too bad.

Has anyone found cracks without a tail strike or heavy turbulence? At this
point we seem to have two instances of crack. Are there others?

I banged the tail tie-down hard enough to bend the "open loop" eye bolt and
grind half an inch off the rudder cap. That was in December 2008. I think
that event may have led to the crack.

No crack in N256H after 934 hrs. No major tail strike, but the SB is still on
the To-Do list.

I purchased my RV-10 a year ago. It was built in 2008-2009. The builder is no longer
alive. How can I
tell if the sb was complied with? What should I be looking for.
Nothing in the logs that I can find.

Have a look at http://www.vansaircraft.com/pdf/sb08-6-1.pdf. That is the
specific bulletin - it details the change and how to spot it.
FYI - for any service bulletins related to vans aircraft, you can find
them here -> http://www.vansaircraft.com/public/notices.htm.

nnual.
I've got 775 hours on the Hobbs. It's been flying for 3 1/2 years.
I've only done stalls a couple times, i.e., Phase 1 and BFRs.
However, the first time I landed with a significantly aft CG it wasn't
pretty. I banged the tail tie-down hard enough to bend the "open
loop" eye bolt and grind half an inch off the rudder cap. That was in
December 2008. I think that event may have led to the crack.
I've been checking it visually at every annual and whenever I have the
panels off at the elevator bellcrank.
At some point during the previous inspections I saw what looked like a
minor wave in the bulkhead and a fine line where there is now
definitely a crack. When I first saw it, I crawled into the tailcone
and was able to feel the area with my fingernail. After first
noticing the "fine line", I watched it very closely at every
inspection. I never noted any change over the next two inspections.
This year it looked more pronounced so I looked even closer. I've
been working as an IA for 20+ years and I've seen a lot of cracks.
Even with my hand on it and solid boroscope inspections, I could not
convince myself that the mark was a crack. We finally confirmed it by
shining a bright light from the front of the bulkhead and looking in
from behind with a boroscope. After disassembly I centerpunched the
outboard rivet at the top of the bulkhead and the crack really jumped
out. Before that, even with the top plate removed and having complete
access to the bulkhead, it was hard to definitively call it a crack.
The repair is pretty straight-forward. The only comment I would make
is to completely remove F-1010A in Step 9. It's only three more rivet
heads and it makes working in the area a lot easier since you can
drive the tails out of F-1010A on the bench instead of with it
attached to the bulkhead.
In the future I plan to treat any warping or marks on the bulkhead as
reasons to add the doublers. The damage seems to have happened
slowly, not suddenly, so the 25 hour inspections seem adequate to
catch the problem. You can see the area through the elevator
bellcrank covers with a bright light, so the inspection shouldn't add
more than few minutes to a preflight.
Last week we inspected another -10 for a customer and there were
definitely no cracks, lines, warping, etc. It just looked completely
different.
I'll post another picture with the doublers installed and the total
time to complete the repair.
Fly safe,
