Good points below, but a friend who just repaired the
following on his LS-3 reminds me...

Many of these LS gliders have rubber shock absorbing
gizmos built into the landing gear - and they are now getting
very old and turning to mush. The glider will typically sit much
lower to the ground then when new (and has less shock
absorption, wrong angle of attack on ground etc).

If the strut wasn't recently replaced, you'll want to have
a good look at that part as well !

Hope this helps,

Speaking of these rubber bushings used for shock absorbing, can anyone
point me to any documentation that describes how to measure the amount
of allowable "give"? I have an LS1f and I have nothing in my
maintenance log that shows these were ever replaced. Would my energy
be better spent on just replacing them? Or is it worth finding the
information needed to measure their current condition?

By the way, my "f" does not have any gas struts any where in the
landing gear system (although some other f's do). I've never had any
issues with it, although it sure is a nice ride on the "sprung" gear.


Thanks,
Dave
