## Discrepancy

DURING CRUISE FLIGHT, THE CABIN PRESSURE WARNING LIGHT ILLUMINATED.  BOTH AUTO AND MANUAL SYS WERE INOPERATIVE.  THE CREW DECLARED AND EMERGENCY AND ALSO REPORTED THAT BOTH ENGINES ECU LIGHTS ILLUMINATED AND BOTH ENGINE TORQUE GAUGES DROPPED TO ZERO.   RESET THE CIRCUIT BREAKER FOR THE ECU AND WERE UNABLE TO DUPLICATE THE ISSUE.
