REFLECTOR: Aircraft leveling

[steve korney]

Something only had to move .0347 of an inch at the pivot to be 2.5 inches 
off at the wing tip...


Best... Steve

Jim,
I am not flying yet but, considering that the cause is not apparent in the 
gear, I would
not fly it until figuring out the source.  Something gave way to cause what 
I believe to
be a significant change after the landing.   If the spar and wings became 
unleveled as a
whole (both sides), and that is probably your case, I would look further in 
the gear and
its structural points.  I would also run your question and final outcome 
through Velocity.
They may have additional knowledge and experience to share with you and as 
Velocity
owners, we want them to be the repository of information so that we all can 
tap into that
knowledge as needed.  My 2 cents.

  After a  really hard landing with side drift the gear on my 173 RG showed 
cracking in the
fiberglass & pain and also the gear doors broke loose, more like a semi 
controlled crash.
After removing the gear and all paint and wraps to the core to check for 
damage, we
determined they were not damaged so redid the lay-ups with carbon fiber and 
reinstalled.
bolts were not bent and go in and out easily and no other apparent damage.  
The camber on
the axels in the same as before in specs and the upper gear fits tight in 
the sockets just
as it did before but now I have one wingtip about 2& 1/2 inches lower than 
the other and
the spar is no longer level sitting on the ground..
Does anyone have any Ideas as to what could have changed to cause this. I 
would guess the
remedy would be to move the sockets but then this would change the camber 
and make it
necessary to fix that also.  Im planning to flyit this way and see if the 
legs change
shape a little after a few landings as everything else went right back in 
place.
Thanks.
Jim
