## Discrepancy

AFTER TAKE OFF FROM SBP THERE WAS A HEAVY VIBRATION FROM THE NOSE LANDING GEAR AREA.  RETURNED TO SBP.    PERFORMED NUMEROUS GEAR SWINGS AND FOUND GEAR DOORS WOULD ONLY CLOSE WHEN UP AND LOCKED HALF OF THE TIME.  REMOVED AND REPLACED LANDING GEAR RELAY BOX IAW 32-31-02 EMB 120 MM.  ALL OPS CHECKS GOOD. DOORS NOW CLOSE NORMALLY.PNON 120-43270-501 SN ON 120150 SN OFF 120124
