Flight Control Failures

Hello,

a clubmate landed his ASH-25 with one of the center flaperons
disconnected and hanging in the full down position. The ASH has three
control surfaces on each wing. His reaction was that the glider had a
great rolling tendancy and needed full opposite aileron and rudder to
keep straight. It was only on final that his rear passenger noted one
flaperon hanging down, so the pilot selected some positive flaps and he
made a good landing.

I also know of a Standard Libelle pilot who suffered aileron flutter
due to some loose connection. Spectators said it was a very nasty
sight, but the landing was fairly ok.
