The pilot reported that during landing, after returning from a maintenance facility, he encountered a quartering tailwind, which "made the airplane drift left of the center." He corrected with right rudder, then applied left rudder which produced a right skid. Subsequently, the main landing gear encountered a "muddy area of the [grass] strip." The airplane nosed over and came to rest inverted, resulting in substantial damage to the airplane. The pilot reported no anomalies with the airplane.
