What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Departed sgj for local flight (steep turns, climbs etc) then returned to sgj for touch & go. On 2nd landing aircraft rolled out to about 15-20 knots & then started turning right. After left rudder & left brake failed to correct the right turn the pilot applied both brakes and the aircraft nosed over onto its back. Pilot states that after the accident he found that he had a quartering tail wind at about 3-7 knots. Note: this light sport aircraft resembles a Piper J3, however unlike a standard J3 it is equipped with disc brakes vs. the less effective "expander tube" design. The aircraft sustained damage to both main wing lift struts, lower cowling, propeller, rudder, and vertical stabilizer.
