## Probable cause

THE PILOT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS. A FACTOR TO THE ACCIDENT WAS: CROSSWIND.

## 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
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - directional control - not maintained, pilot in command
- On ground/water collision with object, landing - roll
  - object - tree(s)
- Nose over, landing - roll

## Analysis

DURING THE LANDING ROLL WITH A 90 DEGREE CROSSWIND, A GUST OF WIND FROM THE RIGHT LIFTED THE RIGHT WING AND PUSHED THE TAIL TO THE LEFT. THE PILOT TRIED TO CORRECT WITH LEFT RUDDER AND APPLIED FULL THROTTLE IN AN ATTEMPT TO BECOME AIRBORNE. THE AIRPLANE TRAVELLED OFF THE SIDE OF THE RUNWAY AND COLLIDED WITH SEVERAL CHRISTMAS TREES BEFORE COMING TO REST INVERTED.

## Factual narrative

On May 1, 1994, at 2015 Pacific daylight time, the pilot of a  tailwheel equipped Cessna 150K, N150S, lost control of the airplane during the landing roll at Chehalis, Washington.  The airplane exited the runway and collided with trees.  Visual meteorological conditions prevailed at the time and no flight plan was filed for the local flight.  The airplane was substantially damaged and the commercial pilot was not injured.

The pilot reported that he was practicing touch and go landings with a 90 degree crosswind.  During the landing roll, the pilot stated that a gust of wind from the right lifted the right wing and pushed the tail to the left.  The pilot applied left rudder control, however, the airplane did not react.  The airplane veered to the right, and the pilot stated that "...in my haste to save the airplane, I pushed in full throttle to try and get the aircraft flying again and straighten out."  The airplane travelled off the side of the runway and collided with several Christmas trees near the runway before coming to rest inverted.
