## Probable cause

The pilot's inadequate crosswind compensation, which resulted in a loss of directional control.

## Findings

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

## Analysis

The pilot stated that while landing on his private gravel airstrip, he was compensating for a slight crosswind. He did not respond quickly enough to maintain directional control of the airplane and the left main landing gear wheel went into a shallow ditch. The airplane veered off the runway and nosed over. The pilot reported that there were no preimpact mechanical problems with the airplane. The airplane sustained structural damage to the wings and vertical stabilizer.

## Factual narrative

The private pilot reported he was on a personal, Title 14 CFR Part 91 flight to his private airstrip. He stated that while landing on the gravel airstrip he was compensating for a slight crosswind. He said he did not respond quickly enough to maintain directional control of the airplane, and that the left main landing gear wheel went into a shallow ditch, pulling the airplane off the runway, where it nosed over. The pilot indicated that there were no preaccident mechanical problems with the airplane. The airplane sustained structural damage to the wings and vertical stabilizer.
