## Discrepancy

(CAN) DURING DESCEND IN PREPARATION FOR LANDING FLIGHT CREW SELECTED FLAPS DOWN TO 17 DEGREES. THE FLAPS DID NOT OPERATE AND THE SELECTOR WAS RETURNED TO ZERO.  CREW LANDED AIRCRAFT WITH ZERO FLAPS. MAINTENANCE DISCOVERED THE R/H SPLIT FLAP SAFETY SWITCH FAILED DISABLING POWER TO THE FLAP MOTOR. SPLIT FLAP SWITCH REPLACED AND FLAP OPERATION CHECKED OKAY.
