The Puch is overepresented in these kinds of accidents.
And generally with an instructor on board. And not spinning

the circuit, but spins deliberately initiated at altitude.
They recover just fine 99.99% of the time. But it seems that

.. no.
All the Puchacz spin ins I know of had a most likely reason that
n
recovery action was initiated.
One because a couple of instructors kept it spinning until too
low
t
recover. There was a voice recording and no indication of a
proble
recovering, or any attempt to do so.
One because it had a low cable break and the instructor did a
low circuit
got too slow round the final turn.
One because the pupil froze on the controls so the instructor
couldn't ge
the stick forwards. I saw that one.
And one where the instructor seems to have had a heart attack
and the pupi
didn't cope.
The Puchacz recovery process is normal and what matters is to
move th
stick forwards to pitch the nose down to reduce the angle of
attack and s
unstall the wing. It takes more movement than a Ka13 but not
more than
lot of single seaters.

Well said Chris! The Puchacz is a superb training machine . It
comes out of the spin as well as it goes in! Anything will hurt if
you don’t use the correct recovery procedure of spin too close to
Mother Earth.

P.S. I think the accelerated spin to which you refer is called a high
speed stall with yaw in the U.K..
