Lee,
    Excellent records.
    Defining 'cause' of a crash as -- the last event before loss of control
or impact --  of the 93 accidents on your list, I labelled 16 as caused by
an 'unintentional stall', (US).
.  That includes two trying to lift off in ground effect, which is kind of
stalling while on a ground cushion of air.  That is also an unintentional
stall, and woujld make it  18 'US'.  Fifteen of the crashes caused preceded
by unintentional stalls were fatal, one serious and one - serious
injuries...  stalling during a steep turn into the trees near a friend's
airstrip
   In other words, if these pilots 'unintentionally stalled' anywhere but in
ground effect, the odds were 15-to-1 against them.
    Airplanes don't stall unless the pilot pulls the wing to a stall AOA.
The 'US' occur because pilots can't SEE what they're doing to the wing's
AOA.
    Further, some of your crashes mentiono no recovery from a spin.  Spins
start with a stall; and the things I've been reading about the LNC2 are that
the horizontal tail is marginal.  That means it needs something to provide
power to piutch the wing's AOA back down to a flying angle... either more
area, maybe added with a strake which could also produce a big vortex at
high angles, good also for preserving rudder power to stop rotation. Slots
work nicely too; I tried them on my AristoCraft.
 But I think the Navy's success with AOAs shows that the best, immediate
help for avoiding unintentional stalls.
Just some observation.  M ight be helpful.
