## Discrepancy

DURING CLIMB FROM YYC, CAPTAIN'S ADI HAD NUMEROUS INTERMITTENT GYRO FLAGS AND ADI WAS ERRATIC.  IN CRUISE, INTERMITTENT ROLL FLAGS.  REMOVED AND REPLACED NR 1 VERTICAL GYRO IAW DC-9 AMM 37-27-01-4.  SYSTEM OPS CHECKED GOOD. (CACTUS CALL OUT OF YYC ENROUTE TO FAR) THERE WERE NO PARTS IN FAR, SO DECISION WAS MADE TO ROUTE MXA OVER FAR DIRECT TO FSD.
