| Subject: | RV-7 loss -> tail inspections -> spar cracks and loose jam |
nuts found
A thread at VAF discusses the results of empenage inspections after the
recent loss of an RV-7.
(http://www.vansairforce.com/community/showthread.php?t=104551) A
couple of spar cracks were found, as were several instances of loose jam
nuts on rudder/elevator rod end bearings.
Those rod end bearings form the hinge pivot for our elevators and
rudders. My understanding: If the jam nut is tight, the spar is held
in compression between the rod end bearing's plate nut and jam nut. If
the jam nut comes loose, the loads from the rod end bearing transfer to
the rudder/elevator spar only through the rivets holding the platenuts
to the spar. Not so good.
Prompted by this thread, I inspected my RV-10 tail structure. No spar
cracks found. But I found that the top rudder rod end bearing jam nut
(page 11-7, similar to plans page 11-2) was loose. The torque seal on
this nut was (obviously) broken.

I ordered the air valve back in August, and received an email
confirmation and PayPal debit immediately. In the last three months I
have repeatedly tried to contact Eric thru email and phone calls, but
have never heard back from him. The archives report several other such
incidents, but none that have gone on for this long. Pretty crappy way
to run a business, even a part time one. Does anyone know if this guy is
still around?
Does anyone know of another source for a air-valve other than the one
Vans sells?

Bill,
Two forklift supports was 3 x 5 x .188" Across rear was 4 x 4 x.188" . Slid in
each side was 3.5 x 3.5 x188" tube that was welded to 18" of heavy 8" c chan.
Center front was 24" 8" c chan. 1" pipe weld on each rear skid for handles and
also round support for straps to pull down on landing gear. Flat bar welded
for and aft of each tire to gain extra wedge for tires to ride in.
When I get it back from paint shop I can send you better pictures and dimensions.
It took about a hour to weld up and about $300 of metal but I was not going
to chance rolling all that work up a ramp and end up upside down during unload
at paint shop. This was quick and secure and can be used by others once we
are done with it.
Hope this helps and let me know what else you need.
