## Probable cause

PILOT'S FAILURE TO COMPENSATE FOR THE WIND CONDITIONS AND HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING THE LANDING ROLL. CONTRIBUTING TO THE ACCIDENT WAS THE GUSTING 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 - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - building(nonresidential)

## Analysis

THE PILOT SAID HE LANDED ON RUNWAY 13 AND THE AIRPLANE WAS BLOWN OFF THE RIGHT SIDE OF THE RUNWAY BY A STRONG GUSTING WIND. THE AIRPLANE STRUCK A HANGAR THAT IS IN CLOSE PROXIMITY TO THE RUNWAY. THE WIND AT THE TIME OF THE ACCIDENT WAS FROM 200 DEGREES AT 10 KNOTS WITH GUSTS TO 15 KNOTS.
