Aviation Accident Final Report - National Transportation Safety Board
Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Helena, Montana
Location: Hamilton, MT
Accident Number: GAA19CA408
Date & Time: 07/12/2019, 1230 MDT
Registration: N7409K
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
Analysis
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 a left turn, and he thought he used the right rudder, but he mistakenly used brake pedal. Immediately thereafter, the airplane 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 pilot reported that he believes the accident could have been avoided "if [he] had kept [his] feet on the rudderbars until [the airplane] had exited the runway."
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's loss of directional control due to his unintentional use of brakes instead of the rudder during the landing roll, which resulted in a nose-over.
Findings

Brake - Unintentional use/operation (Cause)
