DO YOUR CONTOL CHECKS!

Was a 2-33. Heard about it secondhand (or I'd give more
detail). I've seen service difficulty reports in Cezznas,
dunno if there are such things for gliders, maybe the
mechanic who fixes it will give official details...I'll
ask...

Recently, however, during a PCC a bellcrank broke and
this was caused by the pressure exerted by the "helper."
Nice to have this happen on the ground, and I can't
think of how this could have been detected without
a PCC. So now I think a PCC is useful too...

WHat aircraft was this, which bellcrank, and how was the helper exerting
pressure? Or was he simply holding the surface steady while the pilot
applied the pressure? What, exactly, broke (bellcrank, mounting of the
bellcrank, a bearing), and why did it fail?
