IIRC, There was a specific non-combat maneuver which, when
removed from the
pilot's repertoire, cut the accident rate in half, for
both models. It was
called, among other names, "bow to the crowd". It was done
in a hover, and
was a tip the nose down and return maneuver that
accentuated some instability
in the hover, and caused several crashes over the years.

Seems to me there was also a problem with "weathervaning"
under certain wind conditions that caused instability and
loss of control.

I've seen a couple of mishap videos where "airshow" type
manuevers caused losses.
