[rebel-builders] S/M FUS 331 Reinforcement
Posted: Sun Feb 19, 2012 11:13 am
Hi Tom: A while ago I posted pictures in SR/Moose landing gear section
titled Redesigned Fus 331. This is a new gear fitting to capture the top of
the gear leg. Very similar to what you are doing except the bolt is only
subjected to "shear loads". There is a drawing (ACAD) available. We had
these new fittings made at 1 1/2" wide are an easy bolt in replacement.
Again, these should compensate for a less then perfect landing. - Bob J

For those interested, I just uploaded a few photos of a modification I
made
to my FUS 331 gear mount. I put them in section 124 S/M-Modifications.
It's
an attempt to reinforce the area around the bolt. The one gear failure we
all saw photos of showed that this bolt sheared through the thinnest
section
of FUS 331 after the failure of the outer gear mount bolt/nut assy. Most
of us have gone to the next larger bolt AN8 which further decreases the
wall
thickness where the failure occurred. I also remember someone mentioning
that they are seeing some wear/enlargement of this hole with time. My
belief (hope) is that the steel clamps around this area will minimize wear
and lesson the chance of catastrophic failure with my less than perfect
landings.
Regards,
Tom Packard
