Hi Tom,
The ''operating and maintenance manual'' in English is available on this web site (see download). It has been scanned from my personal Canadian ASW 15 and the works of few members from here (+ web site creator). If you want more info, look on the Alexander web site. I've already contact them successfully for few minors things.
About the fungus AD, you just have to inspect inside the wing for contamination by the access panel on the side of the wing (side with attachment to fuselage) and by the access panel cut in the intrados (hole cut by the AD (mandatory)). You need mirror with extension, small flash light and a good eye
My glider has been impacted by this AD in 1988 and still does not have any new contamination. If you found something wrong, the aircraft is grounded until problem fixed.
There is also few AD to check but also 2 others important to check: rudder gap (easy to check) and elevator bellcrank if the mod is not done. Check also if ailerons have friction with wings. My glider had this problem after not flying for 3 years and stored in humidity condition. Drying the glider 2 days under the sun fixed the problem by itself before I got a fix procedure (sand the wing) from Alexander schleicher. Still no issue after 200 hours and lot of fun.
I hope this help. I'm not an expert for glider inspection but I'm well implicated in the inspection of my glider. (My AME is my friend and my crew chief at work and I'm also an avionic AME)
