## Discrepancy

ON AUGUST 8, 2010 WHILE ON APPROACH, THE "LANDING GEAR WARNING HORN" SOUNDED INTERMITTENTLY WHILE THE "GEAR HANDLE" LIGHT AND RED TRANSITION INDICATOR LIGHTS FLASHED.  ACFT MADE SAFE LANDING.  MX REVEALED THAT THE PSEU (PROXIMITY SWITCH ELECTRONIC UNIT) WAS AT FAULT.  PSEU WAS R & R , OPS CHECK WAS SATISFACTORY.  ACFT WAS RELEASED AND RETURNED TO SERVICE.
