Subject: RV8-List: Air Ramp Cracking
After a mere 60 hours TT I have
noticed cracks around rivets on the F867 air ramp on my
RV8A. The cracks are at the outboard rivets that
attach the air ramp to the center F867D stiffener. I
suspect there is a lot of vibration from the engine exhaust
pipes that end just about in that area. I have the
standard Vetterman exhaust bought through Vans and after
about 20 hours or so I added a set of 20 degree turndown
exhaust extensions from Vetterman. The
extensions seemed to help overall noise and vibration
in the cockpit, but obviously there is still a significant
amount of vibration causing the ramp to crack. It
looks like I'll have to replace the ramp, but that is
not addressing the root cause of the problem.
Has anyone else seen and solved this problem?
Additional stiffeners on the air ramp? Longer exhaust
extensions? Any help would be appreciated.
Thanks in advance.

Probably not on this E-mail list but if you do a search on the larger lists I am
sure it will come up.
Adding a doubler, in my case stainless, is so easy to do especially when building
why not just do it. At least that's my thinking.

Oh I also bonded it with Pro-seal to hopefulle stop

exhaust
ramp Its a simple fix that actually looks good with

After a mere 60 hours TT I have
noticed cracks around rivets on the F867 air ramp on
my
RV8A. The cracks are at the outboard rivets
that
attach the air ramp to the center F867D
stiffener. I
suspect there is a lot of vibration from the engine
exhaust
pipes that end just about in that area. I have
the
standard Vetterman exhaust bought through Vans and
after
about 20 hours or so I added a set of 20 degree
turndown
exhaust extensions from Vetterman. The
extensions seemed to help overall noise and vibration
in the cockpit, but obviously there is still a
significant
amount of vibration causing the ramp to crack.
It
looks like I'll have to replace the ramp, but that
is
not addressing the root cause of the problem.
Has anyone else seen and solved this problem?
Additional
stiffeners on the air ramp? Longer
exhaust
extensions? Any help would be appreciated.
Thanks in advance.
