## Discrepancy

DURING REPLACEMENT OF THE NOSE GEAR ACTUATOR, THE PIN RETAINER FOR THE ACTUATOR/UPLOCK WAS FOUND CRACKED UNDER THE HEAD OF THE RETAINING BOLT. SUBMITTER STATED IF FAILURE HAD OCCURRED, IT MAY HAVE GONE UNDETECTED FOR SOME TIME DUE TO THE LOCATION. MALFUNCTION OF NG RETRACTION WOULD HAVE RESULTED.
