Narrative:

While under ATC radar control in approved practice area (which is 5 NM north to south and 0.5 either side off the shoreline). I was advised by the ZZZ1 ATC controller that I'm too close to the ZZZ3 power plant and advised to move north. I did move north within the approved practice area boundaries, finished the aerobatic mission and canceled the flight following, came and landed back at ZZZ2. During the aerobatic flight I was never below 5500 ft into the approved box of airspace (for which there is an approved FAA waiver). After I cancelled the flight following the ATC controller advised me that I'm not supposed to do maneuvers south of ZZZ3 (no NOTAM or facility NOTAM enforced that). After landing I was questioned by my superiors about the flight, because the ZZZ1 ARTCC controller alerted the fighter jets while he was still talking to me. The only NOTAM that I know is do not loiter around power plants. During the whole flight I was in two-way radio communications with the ATC, within the approved boundaries of the FAA waiver and never below 5500 ft. After landing I had to talk with the XXX, ZZZ4, YYY, xyz, and ZZZ1 ARTCC for something that I did not do. The aerobatic flight profile could look like loitering, but this is exactly what FAA in its waiver allow to do within the 5 NM n-s and 0.5 NM either side first officer the shoreline. The waiver states that the altitude for any aerobatic flight is between 3000-7500 ft with two way radio communications and transponder code on.

Title: A 'SMA' PLT VIOLATED A TFR INVOLVING A POWER PLANT.

Narrative: WHILE UNDER ATC RADAR CTL IN APPROVED PRACTICE AREA (WHICH IS 5 NM N TO S AND 0.5 EITHER SIDE OFF THE SHORELINE). I WAS ADVISED BY THE ZZZ1 ATC CTLR THAT I'M TOO CLOSE TO THE ZZZ3 POWER PLANT AND ADVISED TO MOVE N. I DID MOVE N WITHIN THE APPROVED PRACTICE AREA BOUNDARIES, FINISHED THE AEROBATIC MISSION AND CANCELED THE FLT FOLLOWING, CAME AND LANDED BACK AT ZZZ2. DURING THE AEROBATIC FLT I WAS NEVER BELOW 5500 FT INTO THE APPROVED BOX OF AIRSPACE (FOR WHICH THERE IS AN APPROVED FAA WAIVER). AFTER I CANCELLED THE FLT FOLLOWING THE ATC CTLR ADVISED ME THAT I'M NOT SUPPOSED TO DO MANEUVERS S OF ZZZ3 (NO NOTAM OR FAC NOTAM ENFORCED THAT). AFTER LNDG I WAS QUESTIONED BY MY SUPERIORS ABOUT THE FLT, BECAUSE THE ZZZ1 ARTCC CTLR ALERTED THE FIGHTER JETS WHILE HE WAS STILL TALKING TO ME. THE ONLY NOTAM THAT I KNOW IS DO NOT LOITER AROUND POWER PLANTS. DURING THE WHOLE FLT I WAS IN TWO-WAY RADIO COMS WITH THE ATC, WITHIN THE APPROVED BOUNDARIES OF THE FAA WAIVER AND NEVER BELOW 5500 FT. AFTER LNDG I HAD TO TALK WITH THE XXX, ZZZ4, YYY, XYZ, AND ZZZ1 ARTCC FOR SOMETHING THAT I DID NOT DO. THE AEROBATIC FLT PROFILE COULD LOOK LIKE LOITERING, BUT THIS IS EXACTLY WHAT FAA IN ITS WAIVER ALLOW TO DO WITHIN THE 5 NM N-S AND 0.5 NM EITHER SIDE FO THE SHORELINE. THE WAIVER STATES THAT THE ALT FOR ANY AEROBATIC FLT IS BETWEEN 3000-7500 FT WITH TWO WAY RADIO COMS AND XPONDER CODE ON.
