## Discrepancy

THE LT AND RT FLAP IDLER BELLCRANKS, BOTH P/N 5865105-3, ARE FOUND TO BE WORKING BETWEEN THE CAST ARM AND THE TUBULAR BEARING SUPPORT COLUMN.  THE 4 SECURING RIVETS ALSO APPEAR TO BE LOOSE, BUT NOT SHEARED.  IT IS BELIEVED THAT RIVET FAILURE WOULD RESULT IN FLAP BINDING.  THESE WERE FOUND ON A RELATIVELY LOW TIME AIRCRAFT (UNDER 4,000 HRS).  SERVICEABLE BELLCRANKS ARE INSTALLED.
