Narrative:

I was working a student in the area between miami VOR and dade-collier airport at the assigned altitude of 2500'. The student was practicing steep 360 degree turns. The student was having problems holding the altitude I assigned (2500') and I found out later that an air carrier flight reported we were doing aerobatics, and that we were at a much higher altitude. They also stated they had to take evasive action. I never saw the air carrier flight, although I saw numerous large jets inbound to mia and fll, and numerous high wing single engine aircraft at our altitude or below. Most of the deviations from the 2500' were dscnts, and at no time did I allow the aircraft to go above 2700' to 2750'. The lowest we went was 2000' or very slowly below. The first I knew of a problem was on landing at north perry airport, and being told to contact miami approach.

Title: ACR FLT REPORTS SMA TRAINING FLT AS PERFORMING ACROBATICS INTO THE MIA TCA AND POTENTIAL CONFLICT WITH ACR FLT.

Narrative: I WAS WORKING A STUDENT IN THE AREA BTWN MIAMI VOR AND DADE-COLLIER ARPT AT THE ASSIGNED ALT OF 2500'. THE STUDENT WAS PRACTICING STEEP 360 DEG TURNS. THE STUDENT WAS HAVING PROBS HOLDING THE ALT I ASSIGNED (2500') AND I FOUND OUT LATER THAT AN ACR FLT RPTED WE WERE DOING AEROBATICS, AND THAT WE WERE AT A MUCH HIGHER ALT. THEY ALSO STATED THEY HAD TO TAKE EVASIVE ACTION. I NEVER SAW THE ACR FLT, ALTHOUGH I SAW NUMEROUS LARGE JETS INBND TO MIA AND FLL, AND NUMEROUS HIGH WING SINGLE ENG ACFT AT OUR ALT OR BELOW. MOST OF THE DEVS FROM THE 2500' WERE DSCNTS, AND AT NO TIME DID I ALLOW THE ACFT TO GO ABOVE 2700' TO 2750'. THE LOWEST WE WENT WAS 2000' OR VERY SLOWLY BELOW. THE FIRST I KNEW OF A PROB WAS ON LNDG AT N PERRY ARPT, AND BEING TOLD TO CONTACT MIAMI APCH.
