## Discrepancy

(CAN) AFTER TAKEOFF, CLIMBING TO FL 240, THE LT PROPELLER ELECTRONIC CONTROL SHOWED A FAULT AND WAS FOLLOWED BY A NP DROP TO 73 PERCENT.  AFTER A FEW MINUTES OR SO THE ITT RAISED PROGRESSIVELY TO 770C AND NR 8304.  THEN THE MASTER WARNING CAME AND RAPID THE TORQUE, TQ, DROP AND A LOW OIL PRESSURE INDICATION WAS OBSERVED.  THE ENGINE WAS SHUTDOWN AND THE ACFT TURNED BACK.  THE ACFT LANDED NORMALLY IAW THE SINGLE ENGINE PROCEDURES.
