## Discrepancy

NR 2 ENGINE DECELERATED DURING FLIGHT.  ENGINE WAS SHUT DOWN AND A SINGLE ENGINE LANDING WAS MADE.  UPON INVESTIGATION BY MAINTENANCE, THE PR LINE AT THE GOVERNOR WAS EXTREMELY LOOSE. TIGHTENED B-NUT AND ENGINE PERFORMED SATISFACTORY DURING POST RUN-UP.  GOVERNOR AND CONTROL HAD RECENTLY BEEN REPLACED.  NO TORQUE STRIPE WAS FOUND ON FITTING TO INDICATE ANY SLIPPAGE OF NUT.  POSSIBLE CAUSE:  LINE NOT TORQUED PROPERLY.  ALL OTHER B-NUTS WERE CHECKED FOR PROPER TORQUE.  (X)
