Aerobatic pilot reported contacting the ground during a maneuver and damaging the right main gear. Pilot returned to airport and landed on left main and nose wheel. No reported injuries.

Narrative

While practicing aerobatics within wavered airspace of the aerobatic practice area (APA) at ZZZ; the aircraft entered an unacceptable sink rate during a particular aerobatic maneuver. As pilot flying & PIC I immediately aborted the aerobatic maneuver; recovered from the unusual attitude; and aborted the sequence. During the unusual attitude recovery portion the right main gear contacted the ground causing it to be damaged. I recovered the aircraft to a safe altitude; and contacted an airborne observer to assist me in assessing the damage. Via a formation rejoin it was determined the right main landing gear was bent significantly. I radioed a resource on the ground via VHF radio and requested crash; fire; rescue response and additional personnel on the ground to stand by. With crash fire rescue (CFR) in place I conducted a straight in approach to Runway XX and landed uneventfully on the left main and nose gear; and emergency ground egresses the aircraft with my student. No airport property was damaged and neither myself or my student sustained any injuries whatsoever. Once safely on the ground I spoke with the FAA and received clearance to remove the airplane from the runway.
