## Probable cause

The pilot’s failure to maintain directional control during the landing rollout in crosswind conditions, which resulted in a runway excursion and impact with equipment.

## Findings

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

## Sequence of events

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

- [Landing: Runway excursion](https://openairdocs.org/ntsb-events/300) (defining event); cases with it: [Consolidated Aeronautics LAKE LA-4-200, 4 cases](https://openairdocs.org/ntsb-events/300/sequence.md?model=2400108), [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md)

## Analysis

The pilot reported that, he was conducting touch-and-go landings in gusty crosswind conditions. After touchdown and during the landing rollout, the airplane encountered a strong wind gust and veered to the right. He attempted to correct for the veer to no avail. The airplane subsequently exited the runway and impacted weather reporting equipment located on the airport, which resulted in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
