## Discrepancy

UNABLE TO RETRACT LANDING GEAR.  THE NLG LOWER STRUT ASSEMBLY WAS FOUND TO BE ASSEMBLED INCORRECTLY.  THE UPPER CAM WAS MISALIGNED PREVENTING THE SHOCK ABSORBER LUGS FROM ENGAGING INTO THE SHOCK STRUT BACKPLATE.  THE NLG LOWER STRUT ASSEMBLY, WHEELS, TIRES AND APPLICABLE SENSORS WERE REPLACED.
