## Discrepancy

GRR - FLT 1123 - THE FLIGHT CREW EXPERIENCED TORQUE FLUCTATIONS OF THE RIGHT ENGINE IN-FLIGHT, TURNED BACK TO GRR.  THROUGH TROUBLESHOOTING, MAINTENANCE FOUND THE PRIMARY GOVERNOR FAILED AND REPLACED IT.  DURING A RUN-UP CHECK, THE RIGHT AUTOFEATHER WAS TESTED ON THE GROUND AND THE RIGHT PROPELLER STAYED IN FEATHER.  MAINTENANCE CHANGED THE OVERSPEED GOVERNOR CLEARING THAT PROBLEM.  PN, 122-389037-3, SN 2699964A, TSN:  5,372.6 HOURS.  (X)
