The pilot of the tailwheel-equipped airplane reported that, while landing on a grass runway, the airplane nosed over. The pilot acknowledged that he likely landed with the brake pedals depressed. He checked the wheels and they moved freely.

The airplane sustained substantial damage to the fuselage, both wings and the vertical stabilizer.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation station located on the airport reported that, about 10 minutes before the accident, the wind was from 210° at 8 knots. The airplane was landing runway 19.
