## Discrepancy

DURING THE DAILY INSPECTION, IT WAS DETECTED THE TOP BOLT IN THE NOSE GEAR SCISSOR LINK WAS SHEARED.  THE GEAR WAS INSPECTED AND NO DEFECTS NOTED.  THE BOLT WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE. (HAVE SEEN THIS ONCE BEFORE ON ANOTHER TWIN OTTER ABOUT 6 MONTHS AGO) THE BOLT SHEARS WHERE THERE IS A GROOVE CUT IN THE SHANK FOR LUBRICATION.
