## Discrepancy

NLG DOOR LIGHT FLASHED PERIODICALLY DURING CLIMB AND LEVEL OFF. NO INDICATION DURING LEVEL FLIGHT.  NO DOOR CHATTER SOUND ASSOCIATED.  REMOVED FROM SERVICE.  PERFORMED GVI OF THE NLG DOORS AND HINGES WITH NO DEFECTS NOTED.  INTERROGATED PSEU AND FOUND THE NG DRCL SENSOR OUT OF LIMITS.  MOVED THE NLG DOORS BY HAND TO SIMULATE TURBULENCE AND WAS ABLE TO DUPLICATE THE NLG DOOR LIGHT FLICKER.  RIGGED THE NLG DOOR PROXIMITY SENSOR IAW AMM 32-61-06-830-801 AND VERIFIED THE NLG DOOR SENSOR INDUCTANCE IAW AMM 32-61-00-280-801. PROXIMITY SENSOR READS OK, UNABLE TO DUPLICATE DISCREPANCY AFTER RIGGING AND SIMULATING TURBULENCE. NO FURTHER DEFECTS NOTED. RETURNED TO SERVICE.
