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,

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.
