Narrative:
On takeoff; the auto feather failed to arm. The outside air temperature was 26 degrees C and power levers were advanced to 90% before rejecting takeoff. After clearing the runway the crew performed the auto feather/power-up trim test and the auto feather still failed to arm. The crew returned to the gate and the flight was cancelled.the problem was detected using the normal takeoff scan.[this aircraft] has been written up 15 times in the past month for the auto feather system; many of which resulted in rejected takeoffs. Prior to this event; the aircraft had originated from maintenance after having the same write-up the day before; and had flown multiple legs without incident.the crew performed a rejected takeoff and returned to the gate. The auto feather system was meled and the aircraft operated with weight restrictions to [the next airport] where it went to maintenance.apart from fixing the reoccurring issue; the standard operating procedures captured the failure so I can give no additional suggestions.
