Regarding Scott Krueger's note on main gear cylinder bottoming....

This is news.  About 6 months ago, a Lancair tech rep was emphatic that the
NOSE
gear cylinder be setup as Scott describes in order to react the loads internal
to the cylinder.  Issue, as was discussed here, was that the nose gear tunnel
could crack.  When I asked about the mains, I was told this is not a problem
because of the way loads are reacted at the main cylinder attach points.
And in
fact, the inboard supports for the main cylinders do look "beefy".  The problem of a bent cylinder rod as Scott reports may or may not have
anything
to do with bottoming out the cylinder internally.  What would bend that (very
strong) rod?   How would the forces be applied to accomplish this?  I ask
these
arcane questions because I wonder if the rod impacted the inboard linkage
attach
- the one the manual warns us about.  Or, if it's a misallignment during the
stroke that was the culprit then changing the bottoming condition won't
help.  Obviously, first thing I will do when I get to the shop will be to
re-inspect my
installation.
