I inquired about this with Schleicher. This is only an Australian response to superficial cracking in the thickend resin around the spar butt at the wing root. These cracks are the subject of conversation at nearly every annual inspection of all ASK 21s that I look at. They show up fairly early in the service life and I have never seen any of them become more than superficial.

Unfortunately not. I inspected our club aircraft today. The crack has propagated into the bond between the root rib and the spar, right next to the front lift pin on both wings and is proceeding to zipper up the bond line. I'm aware of at least one other aircraft with exactly the same cracking. Happy to share high-res photos if anyone is interested. Far too big to post here. Ping me privately.
