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
