I've been associated with a couple of these situations. *If your shop
knows exactly where, one or two 5cm round holes can be cut in the
bottom skin through which a wrench will fit. *A perfectly round hole
is a simple repair and you'll never see where it was.

Why do you need access?

The ball race that couples to the air brake paddle side has corroded and
needs replacing. *My shop also reckons a couple of holes will be needed to
allow access by wrenches (though the hope is that bolt doesn't have to be
fully retracted). *We were hoping that we could find some pictures of what
we might find before cutting any holes.

Yep, I've seen that. The ASK-21 spoiler boxes, like most composite
gliders, don't have drain holes for water, which has leaked in around
the spoiler cap, to escape. If a glider is to be tied out, it's a
good idea to tape some colorful plastic sheet over the spoilers to
keep water out. I worry a little about using white wing gap tape to
seal the spoiler boxes - someone might not see it and take off with
the spoilers taped shut.
