Disconnecting ASW-20 BL Flaperons

Hi there!

ASW-20 BL c/n 20952 of our club crahsed last summer and now we are inspecting it for repairs. One of the first things to do is remove flaperons. Loosing hinges by drill was quite simple, but how on earth the pushrods can be disconnected? The Wartungshandbuch does not give the answer.

So far it seems that rod end is attached to flaperon by sort of hollow pin (deformed from both ends). Is that correct and does anybody have experience of this matter? Do we have to use drilling machine again? (We have already ordered instructions from the factory, not arrived yet)

Hi Jouni, The ailerons and flaps on your 20 are removed by drilling out the *stop* rivets (I think you have already done this) next you must drill out the steel sleve where the drive is connected. When its time to reinstall, you can get a new sleve from Schleicher or (my solution) replace it with a bolt and locking nut.

I removed the fairing and the two bolts holding the attachment bracket. To reinstall, use a dremmal tool and remove some of the filling on both the wing and fairing. Mix up a real thick batch of epoxy and microballons. Glue the fairing on and fill.
