## Discrepancy

FLT 96 - HNL-KOA - WHILE CLIMBING THROUGH 6000 FEET, FLIGHT CREW REPORTED A PROBLEM WITH THE FIRST OFFICER'S ADI TO MAINTENANCE CONTROL.  MAINTENANCE CONTROL ADVISED THE CREW TO RETURN TO HNL FOR REPAIRS.  LANDING WAS ACCOMPLISHED WITH NO FURTHER PROBLEMS.  MAINTENANCE REPLACED THE F/O'S ADI AND THE NR 2 VERTICAL GYRO.  GROUND OPS CHECK OF THE ATTITUDE SYSTEM TESTED GOOD.  AIRCRAFT RETURNED TO SERVICE.  (M)
