The LBA restricts the AD to DG1000. The EASA mentions "with
unfolding propeller". All gliders in your list have unfolding
propellors except the Ventus CM which means the AD doesn't
apply to it (yet ?).

I have no idea what EASA means by "with unfolding propeller".
On the list above, only the DuoT has a hinged (flapping)
propeller, which would I think reduce fatigue loads. All the
others have conventional one-piece propellers (except maybe a
handful of early Ventus CM which had some kind of asymmetrical
prop; I can't remember if those were hinged)...

I'll try contact SH after the holiday break.

Have a great holiday,
