AIRSHOW PLT PARTICIPANT MADE UNAUTHORIZED LOW PASSES OVER RWY DURING AN AIRSHOW.

Narrative

MY ACFT TOOK OFF FOR THE AEROBATIC FLT DEMONSTRATION. UPON COMPLETION OF THE AEROBATIC MANEUVERS; THE SHOW BOSS REQUESTED AN EXTENSION OF THE FLT DEMONSTRATION; TO ELIMINATE THE LONG VOID UNTIL THE NEXT AND FINAL DEMONSTRATION. I REQUESTED 2 LOW APCHS ON THE RWY TO EXTEND THE FLT TIME. THESE WERE APPROVED BY THE SHOW BOSS VIA RADIO. THE 2 LOW APCHS THEN WERE FLOWN ON THE RWY CTRLINE IN BOTH DIRECTIONS AND FLOWN AT LOW CRUISE PWR IN ORDER TO EXTEND THE FLT TIME TO THE MAX. UPON COMPLETION OF THE 2 PASSES ON THE RWY CTRLINE; I CALLED INBOUND. I THEN LANDED; THUS COMPLETING MY FLT DEMONSTRATION. THE ABOVE WAS A CHRONOLOGICAL NARRATION OF PERTINENT EVENTS THAT TOOK PLACE AT THE SHOW SITE. 4 DAYS LATER I RECEIVED A CALL FROM THE FAA MONITOR OF THE SHOW. HE CLAIMED THAT I HAD FLOWN MY ACFT TOO CLOSE TO THE SPECTATOR LINE. MY REPLY AND UNDERSTANDING WAS THAT THE RWY CTRLINE WAS NOT TOO CLOSE AND ALLOWABLE FOR NON-AEROBATIC FLY-BYS AS NO RESTRICTION WAS NOTED IN THE WAIVER FOR NON-AEROBATIC FLY-BYS. I FURTHER COMMENTED THAT THE AEROBATIC PORTION WAS FLOWN AT THE DESIGNATED DISTANCE FROM THE CROWD PER THE WAIVER. THE FAA MONITOR STATED THAT THIS WAS NOT CORRECT AND THAT THIS ISSUE WOULD BE RESOLVED AT A LATER DATE. MY CONTENTION IS THAT THE WAIVER DOES NOT PRECLUDE NON-AEROBATIC FLY-BYS ON THE RWY; AS LONG AS ALL THE PROVISIONS ARE MET. ADDITIONALLY; I HAD FLOWN THIS SAME SHOW SITE IN 1989 AND 1990; WITH FAA MONITORS PRESENT AND I HAD FLOWN THE SAME FLT PROGRAM WITH THE NON-AEROBATIC FLY-BYS WITHOUT COMMENT OR RESTRICTION. FURTHER; 4 PRIOR ACFT USED THE RWY CTRLINE FOR AEROBATIC AND NON-AEROBATIC DEMONSTRATIONS WITHOUT RESTRICTION (PER THE NARRATION). SHOULD THIS BE AN IMPROPER FLT PROC PER THE PROVISIONS OF THE WAIVER; THE WAIVER SHOULD HAVE CONTAINED DEFINITIONS FOR THE ALLOWED MANEUVERS TO BE CONDUCTED OVER THE RWY CTRLINE. THIS RESTRICTION SHOULD HAVE BEEN PRESENTED TO ALL THE PLTS AT THE PRE-SHOW BRIEFING AND INCLUDED IN THE WRITTEN WAIVER PROVIDED TO EACH PLT. HAD THE FAA MONITOR INTRODUCED HIMSELF AS THE ATTENDING MONITOR AND THUS PRESENTED THE RWY RESTRICTIONS; NO AMBIGUITY WOULD HAVE EXISTED ON THE ALLOWABLE FLT MANEUVERS OVER THE RWY CTRLINE.
