## Discrepancy

THE LEFT PROPELLER WOULD NOT COME OUT OF FEATHER WHEN THE AUTOFEATHER TEST WAS ATTEMPTED PRIOR TO DEPARTURE.  THE AIRCRAFT RETURNED TO THE GATE. MAINTENANCE INSPECTED THE AIRCRAFT AND FERRIED THE AIRCRAFT TO PIT.  MAINTENANCE REPLACED THE LEFT TORQUE SIGNAL CONDITIONER IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 77-11-02.  OPERATIONAL CHECKS WERE COMPLETED AND THE AIRCRAFT RETURNED TO SERVICE.
