## Discrepancy

PRIOR TO BRAKE RELEASE ON TAKEOFF, THE AUTOFEATHER GREEN ARMED LIGHT WAS ILLUMINATED.  IMMEDIATELY AFTER BRAKE RELEASE, THE AURAL WARNING FOR AUTOFEATHER SOUNDED AND TAKEOFF WAS ABORTED.  REMOVED AND REPLACED AURAL WARNING UNIT WITH SERVICEABLE UNIT.  PERFORMED ENGINE RUN-UP AT TAKEOFF POWER SETTINGS WITH AUTO FEATHER SYSTEM ARMED.  ALL CHECKS GOOD, NO AUTOFEATHER AURAL WARNING.  AUTO FEATHER FUNCTIONAL CHECK GOOD.
