Terrence,
   
  What percentage of those 24 planes had AOA indicators, and what is the percentage in the entire fleet, preferably by model?
   
  While AOA is a useful tool, I am not convinced that having AOA and using it under normal conditions will immunize you from a spin under abnormal conditions.
   
  If an AOA systems fails in a non conservative way it could induce an accident that would not otherwise have happened.

  Thanks for the Lancair accident update. 
  Note that of these 126 Lancair accidents, 54 included fatalities, and 24 of the accidents definitely resulted from a stall/spin --  the last pilot-controllable event before the pilot pulled his wing past its stall AOA and became a doomed passenger.
  Note that a wing of a trimmed a/c will not stall unless the pilot pulls the stick back too far, causing his aircraft to pitch up to a stall AOA...
  which he unintentionally does because he cannot SEE the realtive wind and his wing's stall AOA.
  A sad, unnecessary waste of friends' and families lives, beautiful aircraft, and years of creative work, all for the lack of an inexpensive AOA indicator and a little training to develop habitual use of it.
