It does make one wonder. I seem to recall something on r.a.s. to the =
effect
that an inspection of a Puch in the USA turned up a metal plate that =
was
adrift somewhere in the rudder control curcuit. This loose plate, it =
was
said, could prevent the rudder from moving back from the fully =
deflected
position. I seem to recall that it was suspected that some of the =
spin-in
accidents might be due to this.

One day I was told about a Puchacz accident at Bielsko in southern =
Poland, many years ago. The trim handle (a small green ball made of =
fabric) went loose and disappeared. The student replaced it with another =
one, but didn't check where's the one which got lost, and then took off =
for a spin training...
The ball has been left inside, and it managed to get into controls, and =
in the moment they were in spin and tried to move stick forward to get =
out of the spin, it locked itself preventing the stick from moving =
forward. The student with instructor kept on pushing the stick, and =
finally hit the ground killing themselves.
Finally it became clear that if they had moved stick back for a second, =
they could survive, because thic could loosen the ball...

I just wonder how the student stupid had to be to not check the glider =
throughly after noticing that the handle has gone.
