A Z50L PLT; UNABLE TO SALVAGE A MISCALCULATED LNDG AT GRIFFIN; GA (6A2); ACCELERATED DOWN THE RWY TO A HIGH SPD; THEN PITCHED UP TO A HIGH DEG; WHILE ROLLING INTO A 45 DEG BANK TURN; TO RE-ENTER THE TFC PATTERN.

Narrative

ON THE MORNING OF THE EVENT; I CALLED GRIFFIN UNICOM 5 MI OUT REQUESTING ARPT ADVISORIES; WITH NO ANSWER. THEN; 3 MI OUT; AND WAS TOLD THEY WERE LNDG RWY 32. I CALLED DOWNWIND AND BASE TO FINAL TO LAND RWY 32. XING THE THRESHOLD MY SPD WAS 20 MPH FAST. I SLOWED TO A 3-POINT ATTITUDE AND FLOATED. MY AIRPLANE HAS A 110 KMH BRAKE APPLICATION SPD SO I ADDED FULL PWR AND ANNOUNCED MY GAR. I ACCELERATED DOWN THE CTRLINE TO 200 KMH AND PITCHED UP AND THEN ROLLED INTO A 45 DEG BANK. THE AIRPLANE CLBED RAPIDLY AS EXPECTED AND I AM CONFIDENT I WAS CLRLY ABOVE 500 FT AGL BEFORE LEAVING THE RWY ENVIRONMENT. I REDUCED PWR SO AS NOT TO ACCELERATE AND LEVELED AT PATTERN ALT. AGAIN; MAKING POS CALLOUTS; I DSNDED IN A TURNING DSCNT (FOR VISIBILITY) AND LANDED. I ROLLED TO 80 KMH WELL BELOW THE 110 KMH LIMITATION BECAUSE OF THE 90 DEG F TEMP AND APPLIED BRAKES AND TURNED OFF THE RWY. AFTER PARKING; A GENTLEMAN APCHED ME SAYING HE WAS THE ARPT MGR AND WAS GOING TO SEEK CERTIFICATE ACTION AGAINST ME FOR PERFORMING AEROBATIC FLT IN THE PATTERN. I TRIED TO ASK HIS CONCERNS AND HE SAID HE WASN'T GOING TO ARGUE; THAT I HAD SINGLE-HANDEDLY SET BACK PUBLIC RELATIONS 10 YRS; AND HE GOT IN HIS CAR AND LEFT. I DO NOT BELIEVE HE WAS ACCUSTOMED TO THE PERFORMANCE OF HIGH SPD AEROBATIC AIRPLANES; AND WAS UNWILLING TO DISCUSS HIS CONCERNS. AT NO TIME DID I EXCEED 45 DEGS OF BANK OR 30 DEGS OF PITCH; NOR DID I PERFORM ANY MANEUVER NOT NORMAL TO THE PERFORMANCE OF THE AIRPLANE. THE ARPT MGR SHOULD BE MORE OPEN TO DIFFERENT ACFT PERFORMANCE AND SHOULD BE WILLING TO DISCUSS A SIT BEFORE TAKING ACTION.
