Ren, that crash in NC didn't involve a stall, but a simple flipover from landing perpendicular to the plowed rows. Aircraft not equipped with a shoulder harness and pilot sustained head injuries and a broken neck. One of our IAC 19 guys is with the Greensboro FSDO and worked that crash. I've always been a fan of shoulder harnesses in airplanes.
I just walked away from an argument with a friend over shoulder harnesses. We both have cherokee 180s, serial numbers about 2 months apart. First thing I did when I bought it, 15 yrs ago, was install shoulder harnesses.
Every time this is brought up to my friend, he claims the installation of the after market harnesses, despite the STC, degrade the structural integrity of the airplane and he refuses.
Unsafe attitude. At least in my opinion.
