The pilot’s failure to maintain directional control of the airplane during the takeoff roll following a hard landing.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Performance/control parameters: directional control](https://openairdocs.org/ntsb-findings/01062020): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Piper PA-18-150, 98 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md?model=7101828), [All aircraft, 3,958 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Takeoff-rejected takeoff: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Piper PA-18-150, 109 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=7101828), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

The pilot reported that during landing, the left wing stalled and the airplane impacted the ground, which resulted in damage to the landing gear and propeller. He attempted to takeoff, but the airplane veered off the side of the runway into small trees, which resulted in substantial damage to the left wing strut and left elevator. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
