## Discrepancy

FOUND DURING PHASE INSPECTION LANDING GEAR RETRACTION TEST;  THE LEFT LANDING GEAR RETRACT ACTUATOR JACKSCREW NUT ASSEMBLY BROKE (THREADED SCREW DISCONNECTED FROM CHROME TUBE), AND THE LEFT LANDING GEAR FELL DOWN, BUT NOT LOCKED.  PROBABLE CAUSE:  BAD ACTUATOR NUT BRAZE.  THIS PROBLEM IS ADDRESSED BY MFG SB.  THE FAILED ACTUATOR NUT WAS ONE OF THE AFFECTED NUT PART NUMBERS IN SB.
