## Probable cause

The pilot's failure to maintain directional control during the landing roll.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)

## Analysis

According to the pilot, he was performing touch and go landings when he lost directional control and departed the runway to the left. The right wing contacted the ground and the airplane nosed over, resulting in substantial damage. An examination of the airplane systems revealed no anomalies.

## Factual narrative

According to the pilot, he was performing touch and goe landings on runway 22 (7,400 feet by 100 feet, asphalt) when he lost directional control and departed the runway to the left. The right wing contacted the ground and the airplane nosed over. The lower right wing ribs were splintered and the main spar was broken.
