Subject: TS Speed versus Spin

        I remember a long thread a while ago on Lancair stall/spin behavior. My recollection was that it was inadvisable to intentionally spin a Lancair, and stall practice was risky and to be treated to the greatest respect. Up comes the discussion on TS and the obvious recommendation is to slow to below maneuvering speed. This keeps the wings on, but raises the risk of uncontrolled spinning. I wonder how a spinning aircraft handles TS loads? Perhaps that's why the FAA is so adamant that certified aircraft be either spin "resistant" or spin "recoverable".

"What this means to me is that pushing the envelope is a riskier proposition in a Lancair than it is in, for
example, a citabria, edge or other airplane ... For this reason, while I would gladly go out any time and do a stall series in a 172,
my experience in my Legacy consists of an approach to stall, done with Don Goetz on board as a part of initial flight testing.  Even with ACM experience under my belt, I not only don't stall my Legacy, I don't come close at any time at which I am not within ten feet of a runway.  It's not because the a/c is too high performance for me; it's because I don't know for sure what it will do and neither does anyone else."
