## Discrepancy

AIRCRAFT RETURN OF FLIGHT, DURING TAKEOFF ROLL, THE NLG HIT A BIG BUMP ON THE RUNWAY AND IT DID NOT RETRACT.  DURING REVISION WAS DETECTED THE NLG SHOCK STRUT LOW.  AIRCRAFT WAS SENT TO HANGAR, WHERE THE PISTON AXLE ASSEMBLY CYLINDER ASSY AND SHOCK STRUT SEALS WERE REPLACED IAW MM.  OVERWEIGHT LANDING INSPECTION WAS PERFORMED IAW MM, ALL CORRECT.
