## Discrepancy

SHORTLY AFTER TAKING OFF FROM ST37 I EXPERIENCED A NR 2 ECU FAILURE TO THE HIGH SIDE.  FOLLOWED THE EMERGENCY CHECKLIST BY GOING TO MANUAL CONTROL OF NR 2 ENGINE AND RETURNED TO BASE WITHOUT FURTHER INCIDENT. THE MECHANICS DETERMINED THAT THE NR 2 ENGINE TORQUE TRANSMITTER FAILED. NOT THE ECU.  REPLACED THE TORQUE TRANSMITTER AND OPERATIONAL FLIGHT CHECKED OK.
