The Puch is overepresented in these kinds of accidents.
And generally with an instructor on board. And not spinning accidentally
in
the circuit, but spins deliberately initiated at altitude.
They recover just fine 99.99% of the time. But it seems that every so
often
.. no.
All the Puchacz spin ins I know of had a most likely reason that no
recovery action was initiated.
One because a couple of instructors kept it spinning until too low to
recover. There was a voice recording and no indication of a problem
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 get
the stick forwards. I saw that one.
And one where the instructor seems to have had a heart attack and the pupil
didn't cope.
The Puchacz recovery process is normal and what matters is to move the
stick forwards to pitch the nose down to reduce the angle of attack and so
unstall the wing. It takes more movement than a Ka13 but not more than a
lot of single seaters.
