## Discrepancy

THE NOSE GEAR WOULD NOT RETRACT AFTER DEPARTURE.  AIRCRAFT LANDED WITHOUT PROBLEMS.  FOUND THE NOSE GEAR RETRACT FORK BOLT BROKEN.  THE BOLT SEPARATED AT THE LAST THREAD BEFORE WHERE THE SHANK STARTS.  THE BELLCRANK THAT THE BOLT SCREWS INTO WAS ALSO DAMAGED AND WAS REPLACED AT THE SAME TIME.  (PN 0842104-3)  SUGGEST THESE BOLTS BE REMOVED AND INSPECTED WITH NDT INSPECTION PROCEDURE.  PROBABLE CAUSE, METAL FATIGUE.  (SW05200403502)
