## Discrepancy

AIRCRAFT RETURNED DUE TO STRONG VIBRATION IN THE NOSE LANDING GEAR AND THREE RED LIGHTS - LANDING GEAR UP TURNED ON.  MAINTENANCE PERSONNEL REPLACED AND TESTED THE PSEU AND NOSE-GEAR STRUT SEALS IAW AMM 32-60-04 AND 32-21-02.  EXTENSION / RETRACTION AND GROUND SENSING CONTROL TESTS WERE PERFORMED IAW AMM 32-30-00, 32-23-01, AND 32-23-01, ALL CORRECT.  THE OVERWEIGHT INSPECTION WAS NOT NECESSARY DUE TO THE AIRCRAFT LANDED WITH 122,000 POUNDS AND THE MAXIMUM LANDING WEIGHT IS 128,000 POUNDS.
