## Discrepancy

THE ACFT TOOK OFF & WHILE IN CRUISE THE COPILOTS AHRS FAILED, CAUSING THE LOSS OF HEADING & ATTITUDE, THE REVERSIONARY SYS WAS USED.  THE PILOTS MADE THE DECISION TO DIVERT & A TECHNICIAN WAS DISPATCHED TO THE ACFT & IT WAS DETERMINED TO BE A FAULTY AHRS UNIT.  THE PART WAS REPLACED & INSTALLATION PROCEDURES WERE FOLLOWED.  OPERATIONALLY CHECKED & THE ACFT RETURNED TO SERVICE.
