Stefan,

I didn't know this.


Because it is not true.

Cirrus chose to comply with the spin certification by installing the
parachute. This was NOT done after spin recovery in the traditional way
had been tried unsuccesfully, as CJ implies. It was done in order to
save money by not doing traditional spin recovery testing at all.

Thus, the official spin recovery testing requried for certification
wasn't done. This says nothing about whether the aircraft is
recoverable from a spin by traditional methods. It was NOT tried, at
least not to the extent necessary for certification. Instead, the
parachute was installed and accepted by the FAA (and EASA) as a
certifiable means of dealing with spins.
