Narrative:

On visual approach to runway 35R at pie, landing checklists completed, I called for the flight directors to be turned off. The captain did not hear and left his on. I turned off the autoplt and began descending manually. At approximately 800 ft, the FMA went to climb from speed and the motors began to spool to climb power. The captain and I realized something was wrong, but at the time didn't know what it was. The captain moved the thrust levers from the climb detent (normal position) to idle, causing the fadec to revert to idle. We had already flattened out the approach too much to land, so I called for a go around. During the go around, the autothrust had been turned off and the heading bug left at 090 degrees from when the autoplt was turning off. The instructions were to climb to 1600 ft and turn left to 270 degrees. Trying to level at 1600 ft, the speed was increasing rapidly, causing the plane to climb. At 2600 ft, we realized that the autothrust was off. I turned on the autothrust and autoplt at the same time. The aircraft stopped its acceleration and leveled at 2600 ft, but started turning toward 090 degrees to the right. I turned the heading bug to 270 degrees and the plane turned back to the left. Finally, everything was normal. We landed at pie with no further incident. Probable causes: lack of follow-up, CRM, lack of proper roles of PF/PNF. Solutions: better CRM and understanding roles of captain/first officer and PF/PNF.

Title: AN ACR FLC FLYING A320 AT PIE FAILS TO SET THE PROPER FLT DIRECTOR MODE FOR A VISUAL APCH WHICH RESULTS IN A GAR.

Narrative: ON VISUAL APCH TO RWY 35R AT PIE, LNDG CHKLISTS COMPLETED, I CALLED FOR THE FLT DIRECTORS TO BE TURNED OFF. THE CAPT DID NOT HEAR AND LEFT HIS ON. I TURNED OFF THE AUTOPLT AND BEGAN DSNDING MANUALLY. AT APPROX 800 FT, THE FMA WENT TO CLB FROM SPD AND THE MOTORS BEGAN TO SPOOL TO CLB PWR. THE CAPT AND I REALIZED SOMETHING WAS WRONG, BUT AT THE TIME DIDN'T KNOW WHAT IT WAS. THE CAPT MOVED THE THRUST LEVERS FROM THE CLB DETENT (NORMAL POS) TO IDLE, CAUSING THE FADEC TO REVERT TO IDLE. WE HAD ALREADY FLATTENED OUT THE APCH TOO MUCH TO LAND, SO I CALLED FOR A GAR. DURING THE GAR, THE AUTOTHRUST HAD BEEN TURNED OFF AND THE HDG BUG LEFT AT 090 DEGS FROM WHEN THE AUTOPLT WAS TURNING OFF. THE INSTRUCTIONS WERE TO CLB TO 1600 FT AND TURN L TO 270 DEGS. TRYING TO LEVEL AT 1600 FT, THE SPD WAS INCREASING RAPIDLY, CAUSING THE PLANE TO CLB. AT 2600 FT, WE REALIZED THAT THE AUTOTHRUST WAS OFF. I TURNED ON THE AUTOTHRUST AND AUTOPLT AT THE SAME TIME. THE ACFT STOPPED ITS ACCELERATION AND LEVELED AT 2600 FT, BUT STARTED TURNING TOWARD 090 DEGS TO THE R. I TURNED THE HDG BUG TO 270 DEGS AND THE PLANE TURNED BACK TO THE L. FINALLY, EVERYTHING WAS NORMAL. WE LANDED AT PIE WITH NO FURTHER INCIDENT. PROBABLE CAUSES: LACK OF FOLLOW-UP, CRM, LACK OF PROPER ROLES OF PF/PNF. SOLUTIONS: BETTER CRM AND UNDERSTANDING ROLES OF CAPT/FO AND PF/PNF.
