Narrative:

This was an aerobatic training lesson. Our aircraft was just recovering from a wing over (nose approximately 10 degrees below horizon and rising, bank approximately 30 degrees and rolling out). At this time my student and I spotted the small transport at 12 O'clock, going from right to left. He was beginning a right bank. We continued our right bank and passed well clear. When we arrived at dispatch I was informed that the small transport had called and reported a near miss. He also complained that we were practicing aerobatics in a busy area. We were clear of all air traffic area's, TCA's, control zones and were more than 4 NM from the nearest victor arwy. I did not believe this was a near miss. No unusual action was required to avoid the small transport.

Narrative: THIS WAS AN AEROBATIC TRNING LESSON. OUR ACFT WAS JUST RECOVERING FROM A WING OVER (NOSE APPROX 10 DEGS BELOW HORIZON AND RISING, BANK APPROX 30 DEGS AND ROLLING OUT). AT THIS TIME MY STUDENT AND I SPOTTED THE SMT AT 12 O'CLOCK, GOING FROM RIGHT TO LEFT. HE WAS BEGINNING A RIGHT BANK. WE CONTINUED OUR RIGHT BANK AND PASSED WELL CLR. WHEN WE ARRIVED AT DISPATCH I WAS INFORMED THAT THE SMT HAD CALLED AND RPTED A NEAR MISS. HE ALSO COMPLAINED THAT WE WERE PRACTICING AEROBATICS IN A BUSY AREA. WE WERE CLR OF ALL ATA'S, TCA'S, CTL ZONES AND WERE MORE THAN 4 NM FROM THE NEAREST VICTOR ARWY. I DID NOT BELIEVE THIS WAS A NEAR MISS. NO UNUSUAL ACTION WAS REQUIRED TO AVOID THE SMT.
