## Discrepancy

(CAN) - ON DEPARTURE OPERATING ON AHRS NR 1, "RED" ROLL AND PITCH ANNUNCIATORS ON BOTH PILOT AND COPILOT PFD`S.  NR 1 PFD THEN SWITCHED TO AHRS NR 2.  THEN BOTH PFD`S TUMBLED.  AFTER 30 SECONDS BOTH PFD`S TURNED "BLACK" WITH "RED" X`S THROUGH THE EHSI AND EADI, WITH "YELLOW" "AHRS RETURN WINGS TO LEVEL" AND "AHRS NR 1 NEEDS SERVICE. RETURN FOR REPAIR" ANNUNCIATION ON PFD`S.  INFORMED BY MFG THAT THEY HAVE FILLED A REPORT IAW FAA 21.3 TO REPORT THE EVENT.  CURRENTLY WORKING WITH MFG TO RESOLVE ISSUE.
