## Discrepancy

DURING A ROUTINE INSPECTION IT WAS NOTICED BY THE TECHNICIAN THAT THERE WAS A LARGE AMOUNT OF VERY THIN GREASE SEEPING OUT FROM AROUND THE MAIN LANDING GEAR ACTUATOR CAPS ON BOTH THE LEFT AND RIGHT SIDES.  THE GEAR ACTUATORS AND PIVOTS WERE FOUND TO BE CRACKED IN THE RADIUS AT THE BOTTOM OF THE GEAR SPLINES.  TO PREVENT THIS PROBLEM IT IS SUGGESTED THAT THE MAIN LANDING GEAR PIVOTS BE REMOVED FROM THE AIRCRAFT AND INSPECTED EVERY 1000 HOURS.  IT IS ALSO SUGGESTED THAT THE MFG OF THIS PART REDESIGN THE PART OUT OF STEEL.  AD ON THE MLG PIVOT ASSEMBLIES HAD BEEN COMPLIED WITH.
