B727 CREW TURNED THE WRONG WAY IN THE HOLD IN ZTL CLASS A.

Narrative

AFTER A PARALLEL ENTRY WAS MADE INTO A PUBLISHED HOLDING PATTERN (ENTRY WAS A L TURN); THE NEXT SUBSEQUENT TURN AT THE FIX WAS A PUBLISHED R TURN. FO WAS FLYING AND UPON REACHING THE FIX MADE A L TURN INSTEAD OF A R TURN. THE FE NOTICED THE MISTAKE AFTER ABOUT 30 DEG OF TURN AND CALLED IT TO THE CREW'S ATTN. THE FO PROMPTLY CORRECTED THE TURN BACK TO THE R. ATC QUERIED OUR TURN AND WAS NOTIFIED OF THE MISTAKE. THE L TURN TO MAKE A PARALLEL ENTRY WAS PROBABLY A CONTRIBUTING FACTOR TO THE L TURN AT THE FIX. ALSO; FATIGUE COULD HAVE BEEN A FACTOR BECAUSE OUR CREW REST WAS SHORTENED THE NIGHT PRIOR TO 8 HRS BECAUSE OF DELAYS AND OUR DUTY DAY WAS IN EXCESS OF 13 HRS TO BE MORE CLR WE HAD A 13+ HR DUTY DAY; 8 HRS OF REST AND THEN THE MISTAKE ON THE NEXT EARLY MORNING FLT. SUPPLEMENTAL INFO FROM ACN 484471: ABOUT 70 DEGS INTO THE TURN AND STILL DSNDING TO FL210; THE SO QUERIED MY TURN AND I BEGAN A STANDARD RATE (OR BETTER) TURN BACK TO THE R. THE CTR CTLR QUERIED OUR ACTIONS AND CAPT TOLD HIM OF OUR CORRECTING MANEUVER. NO LOSS OF SEPARATION THAT WE WERE AWARE OF. AUTOPLT WAS NOT COOPERATING TO MY SATISFACTION SO I DISCONNECTED IT AND COMPLETED TURN AND LEVELOFF MANUALLY. LEVELOFF WAS ROUGH; +/-200 FT. NO INTERACTION WITH CTLR AFTER INITIAL QUERY AND CAPT'S RESPONSE. FO COMPLETED NICE PARALLEL ENTRY AND GOT A L HAND MINDSET. SO VIGILANCE SAVED THE DAY (HOPEFULLY). FATIGUE A POSSIBLE FACTOR DUE TO 13 HR DUTY DAY THE PREVIOUS DAY AND MINIMUM 8 HR REST PERIOD.
