wrote: Have you ever spun one? I will repeat myself, it recovers from most spins with most cockpit loads if you let go the stick, so on the majority of occasions the instructor has to be vigilant that the pupil applies the correct recovery or an incorrect recovery technique will have been learnt. Until now I have not even seen a Puchacz in real life - but the sheer number of spin accidents with experienced pilots suggests that something is wrong, don't you agree? I wonder about "letting go the stick" and letting the glider recover itself - is this really being taught as a procedure? We teach our student pilots to center the stick, and apply opposite rudder - in that order. Letting go the stick is an unknown procedure for me, I have to admit. The DG-500 is fully compliant with JAR22 when the CofG is within limits. When the CofG is near the aft limit it requires the correct spin recovery to be applied, in the correct order, or the ground will do the recovery for you, it will continue to autorotate with the stick on the front stop if you just heave the stick forward without first centralising the ailerons and applying full opposite rudder. It may be possible to recover by applying the full opposite rudder after heaving the stick forward but it will be a delayed recover due to control surface masking. Hmm... looks like the missing 80 cm of wingspan on the 505 really seem to make a difference here - our 505 recovers nicely even at fully aft CG positions. A pilot who has acquired the impression from the Puch that all is required is to let go or relax the back pressure could be killed in this situation. I don't think this is the problem. A typical Puchacz spin accident has the instructor onboard, and I'm pretty sure that most of these instructors knew about the correct spin recovery procedure. Here in Germany we also had our share of Puchacz spin accident. One was a successful spin recovery that went into an opposite spin - the IP was not able to recover the second spin before impact.
