Probable cause

The pilot's incorrect brake and power application during landing, which resulted in a runway overrun, collision with a dirt berm, nose gear collapse, and nose-over.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during the landing roll on a backcountry dirt airstrip, the left wing lifted due to a gust of wind. The pilot further reported that he maintained a faster than normal ground roll by alleviating pressure on the brakes and maintaining some power to taxi up the incline of the airstrip, which was recommended in a YouTube video. As the end of the runway approached, the pilot reported that he was unable to stop the airplane or abort the landing. The airplane overran the runway and hit a dirt berm, which resulted in a nose gear collapse, a nose-over, and substantial damage to the fuselage. The pilot reported there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
