We did ours this summer as in Canada EASA AD's on EASA made gliders come into effect upon issue. Fortunately the closing forces were within spec and there was no damage to the parts. It wasn't that bad except for the derigging, rigging, derigging, rigging cycle needed to get it to the maintenance shop and back and then into the air again.

One thing I was curious about is that our Twin II already has inspection ports in the wings near the airbrake system parts in question but unlike the inspection ports in our Twin Astir RG they don't seem to be large enough to allow removal of the brake parts through them.
