## Discrepancy

UPON GEAR RETRACTION, GEAR WARNING HORN SOUNDED.  PULLED AURAL WARNING CIRCUIT BREAKER TO SILENCE HORN.  RESET CIRCUIT BREAKER BEFORE GEAR EXTENSION, GEAR WARNING HORN CAME ON AND THEN WENT OUT WHEN ALL GEAR SHOWED DOWN AND LOCKED.  REMOVED AND REPLACED FLAP SWITCH S294 IAW MM 312612.  LANDING GEAR WARNING SYSTEM OPERATIONALLY CHECKS GOOD PER MM 326101.
