## Discrepancy

THE FLIGHT CREW REPORTED THE CARGO COMPARTMENT SMOKE DETECTION SYSTEM - HAD THE CARGO SMOKE WARNING TURN ON WHILE IN FLIGHT, DIVERTED BACK TO KFAR, SMOKE WARNING WENT OFF AFTER LANDING IN KFAR.

PERFORMED VISUAL INSPECTION OF THE FIRE DETECTORS AND THE GENERAL AREA AROUND THE FIRE DETECTORS.  NO DISCREPANCIES NOTED.
