High Winds Destroys a Glider

I thought that this would be an interesting reprint (below my
signature) of the last page (un-numbered) of the Schweizer 2-33 manual
which details how to tie down the ship. This page may have been added
to the manual as an addendum after some accidents. The only section
in the main part of the manual (pg 1-8) which deals with tie downs
simply states;
"The 2-33 should never be left unattended in strong winds or gusty
conditions. Tie downs are at each wing where main struts are attached
and at tail wheel bracket. Be sure ropes and stakes used for tying
down are adequate and in good condition."
We had all of these recommendations except for a tail stand. In our
case, raising the tail might have lowered the force on the nose hook,
maybe preventing the hook from failing, and maybe saving the glider.
A lot of maybe's.
Each glider tie down area in Boulder, CO has 4' or so chain link fence
with vinyl slats to break the wind. It disturbs the wind enough to
prevent problems. The region gets 60-70 mph wind every year with 80 mph
wind storms every few years. The power side of the airport had a plane
break loose a year or two ago, but the gliders stay put.
