Aircraft: Piper PA 20
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot of the tailwheel-equipped airplane reported that, upon landing and approaching the taxiway he intended to exit, he lifted his feet from the "rudderbars" to engage the brakes. The airplane abruptly entered into a left turn and he "jabbed at the right rudder," but mistakenly utilized brake pedal. The airplane immediately nosed over.

The airplane sustained substantial damage to the right wing lift strut and rudder.

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

The airport's automated weather observation station reported that, about the time of the accident, the wind was from 010° at 6 knots. The airplane was landing on runway 34.

The pilot reported that he believes the accident could have been avoided "if [he] had kept [his] feet on the rudderbars until [he] had exited the runway."
