Yet another Cirrus flying in coffin corner at high altitude in
turbulence.
It seems to me that if airline pilots can be taught to do this without
falling out of the sky, then surely a Cirrus pilot can be taught the
same,
or at least, like the rest of us, just stay out of there.

How can you discern that from the story? Nothing in the text says
that the airplane was at high altitude, only that it got into a spin
due to extreme turbulence. Did you have access to additional
information not given in the story that the posted URL gives you?

My question would be: why was the pilot flying the airplane in a
thunderstorm? Was he flying in clouds and encountered an embedded
stormcell?

Can you expand on your comment about coffin corner? My understanding
of coffin corner relates to jets flying high enough that their
indicated cruise speed is approach their indicated stall speed.

I looked up the SR22 POH for cruise speeds, stall speeds, etc.

If the SR22 was throttled back for economy or maneuvering.
47% pwr cruise @ 16000 feet = 162 KTAS
@ 16000 pressure altitude, 162 KTAS ~= 123 KIAS

Even at worst case CG and weight, stall speed for the SR22 is 70 KIAS.

That leaves margin of 53 kts. Seems ample to avoid a stall.

I do wonder what caused the pilot to stall @ 16kft.
