Our club's Twin III had a major problem that was found in a Positive
Control Check, the bolt holding the belcranks for the airbrakes and
the elevator (located behind the rear seat in the control hookup area)
had sheared.

Grob will probably be doing an AD for instpection soon, our plane is
at Grob right now being inspected (they are only a 20 minute drive
from the club!).

Please inspect your Twin III before you fly in again.

And for those of you who don't feel the need to do a PCC .... This
wouldn't have shown up with a visual inspection nor probably on a
"hands on" inspection.
