## Discrepancy

DURING A 100-HOUR INSPECTION, THE RIGHT MAIN LANDING GEAR ACTUATOR ASSEMBLY PN 9882015-2 ATTACH BOLT WAS FOUND LOOSE WHICH ALLOWED THE ACTUATOR TO HAVE MOVEMENT DURING RETRACTION AND EXTENSION.  UPON FURTHER INSPECTION OF THE ACTUATOR HOUSING PN 1281001-3, A CRACK WAS FOUND UNDER THE BEARING CUPS PN S1997C-8 ON BOTH SIDES OF THE HOUSING.  INSPECTION OF THE LEFT MAIN GEAR ACTUATOR REVEALED SIMILAR CRACKS; THUS, REQUIRING REPLACEMENT OF BOTH ACTUATORS WITH SERVICEABLE UNITS.
