## Discrepancy

DURING FLIGHT, THE CREW REPORTED CARGO DOOR OPEN INDICATION.  THE CREW MADE AN AIR-TURN-BACK.  THE AC WAS INSPECTED BY MECHANIC WHO CHECKED THE PSEU`S MEMORY AND FOUND THE CARGO DOOR OVER-CENTER PROXIMITY SENSOR HAD LOGGED SEVERAL FAULTS.  MECHANIC REPLACED THE PROXIMITY SENSOR.  THE AC WAS RETURNED TO SERVICE WITH NO FURTHER DEFECTS. (K)
