Analysis

The commercial plt was flying his experimental acro sport 1 in the local area. After about an hour of acrobatic practice, he returned for landing to his home arpt. The plt accepted rwy 28 due to heavy traffic. The winds were reported as 050 degrees at 8 knots, a quartering tailwind. Upon touchdown, the acft turned left and the plt corrected alignment. Directional control was lost and the acft departed the rwy to the left, into soft ground, and nosed over, coming to rest inverted.
