## Discrepancy

THE NLG WOULD NOT RETRACT AFTER TAKEOFF FROM BOS.  THE AIRCRAFT WAS RETURNED TO BOS WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE SWUNG THE NOSE GEAR SEVERAL TIMES AND WAS UNABLE TO DUPLICATE THE FAILURE.  THE STRUT PRESSURE WAS FOUND LOW.  THE NOSE STRUT WAS SERVICED AND THE NOSE GEAR WAS LUBRICATED IAW MM 32-21-02.
