the most popular way to screw up?


The best way to make it terminal seems to be to get the loading wrong in
such a way that you can't recover from the spin. According to a fellow I
spoke to at the Maule factory, it is nearly impossible to recover in an
MX-7 with the CG at one extreme of the envelope (he did not remember
which extreme but thought it might be aft). Maule placards the aircraft
"Intentional spins prohibited." Between 5 and 10 years ago, two CFIs
died in a PA-28 near Solberg when the spin went flat. The last time this
thread surfaced, several people said that loading is also critical in
some models of C-172.

Loading is important is pretty much all airplanes. Having the CG too
far aft will tend to induce a flatter spin and give the rudder less
authority.
