## Discrepancy

AFTER TAKE OFF FROM ITHACA, NEW YORK TO PHILADELPHIA, PENNSYLVANIA ON FLIGHT 5460, THE CABIN DOOR ANNUNCIATOR ILLUMINATED. THE AIRCRAFT WAS THEN RETURNED TO FIELD WITH NO FURTHER INCIDENT.

THE CORRECTIVE ACTION WAS THAT THE MECHANICS CLEANED AND ADJUSTED  THE ASD SAFETY SWITCHES. NO PARTS WERE USED.
