## Discrepancy

UPON REMOVAL OF RUDDER FOR REPAIR TO RUDDER TOP AND MIDDLE RUDDER NEEDLE, BEARING ASSYS FELL APART, I.E., NEEDLES FELL OUT.  PRESENTLY, CESSNA HAS NO INSPECTION INTERVALS FOR THESE BEARINGS.  THERE NEEDS TO BE SOME KIND OF INSPECTION INTERVAL IN WHICH THE BEARINGS ARE INSPECTED AND LUBRICATED AT A SPECIFIC TIME.
