## Probable cause

The pilot failed to maintain directional control and his inadequate compensation for wind conditions.  Factors associated with the accident were the gusty crosswind and the concrete culvert that the airplane contacted.

## 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
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - drop-off/descending embankment (contributing factor)

## Analysis

The airplane collided with a concrete culvert following a loss of directional control while landing.  The landing was being made on runway 18 (3,598 feet by 75 feet, asphalt).  Local  winds at the time of the accident were reported as being from 240 degrees at 12 knots, gusting to 21 knots.  The pilot stated he lost control during the landing due to the wind gusts.  The airplane exited the left side of the runway where it contacted a concrete culvert.  The airplane traveled through the culvert prior to coming to rest.
