## Discrepancy

(CAN) PILOT REPORTED THAT HE WAS HAVING DIFFICULTY CYCLING THE PROPELLERS AND THAT IT APPEARED THAT THERE WAS SOMETHING BLOCKING THE CONTROL.   MAINTENANCE REMOVED THE THROTTLE QUADRANT COVER AND FOUND THAT THE PROPELLER FEATHER STOP HAD BROKEN INTO TWO PIECES. IT WAS INTERFERING WITH THE MOVEMENT OF THE PROP CONTROL LEVER. AT THIS TIME WE HAVE REPLACED 10 FEATHER STOPS IN 3 SEPARATE AIRPLANES SINCE APRIL 2010.
