Posted for "John Barrett" <2thman@cablespeed.com>:

  Excessive wear is the very nature of aluminum in a hinge environment.  The
  wear is not on the pin, but rather on the inside diameter of the hinge
  itself.  Aluminum is a relatively soft material and it corrodes easily.
  Logically as the aluminum wears away on the inside diameter that houses the
  pin, you would conclude that the slop would increase over time.  Flutter is
  caused by unbalanced control surfaces.  I don't think loose pins would
  necessarily lead to flutter, but perhaps, if there is a minor imbalance,
  movement allowed between the control surface and airframe via a sloppy
  fitting hinge could move you closer to destructive flutter.
