LS 6 Undercarriage collapse

So, a few years back, there was a spate of undercarriage collapses on
LS 6 sailplanes and a Technical Bulletin was issued by the LBA on how
to fix the problem.

Does anyone know if the suggested replacement part for the gas strut
(4R2-111) is still available?
Were there any other fixes enacted for this problem?

Thanks for any info,

Bob

My LS6C is much later than the gliders in the TM if I recall correctly the
later ones were manufactured with a solid bar in place of the gas strut
and the bulletin is to replace the gast strut with a bar.

Unfortunately DG have changed the production LS8 undercarriage so they may
not have the same part.

My glider does have a small sliding clip to prevent the undercarriage
jumping out of the gate which was fitted by the previous owner after an
undercarriage collapse, it certainly looks like an LS part as it matches
the cockpit paint.

I believe that it is also a good idea not to leave the wheel fully
retracted when the glider is derigged and in its trailer. This is because
there are some rubber suspensions blocks that can become compressed over
time and reduce the over-centre locking effect.
