## Probable cause

FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL, WHICH RESULTED IN AN INADVERTENT GROUND SWERVE. FACTORS RELATED TO THE ACCIDENT WERE: THE GUSTY CROSSWIND CONDITION, AND PILOT FATIGUE.

## 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)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
  - fatigue, pilot in command (contributing factor)
- Main gear collapsed, landing
  - landing gear,main gear - overload

## Analysis

AS THE PLT WAS LANDING WITH A GUSTY X-WIND, THE ACFT SWERVED TO THE LEFT AFTER TOUCHDOWN.  SUBSEQUENTLY, THE RIGHT AXLE FAILED & THE RIGHT GEAR COLLAPSED, THEN THE RIGHT WING IMPACTED THE GROUND AT THE EDGE OF THE RWY. THE PLT RPRTD THAT HE MAY HAVE BEEN FATIGUED DUE TO HIS LONG DAY OF TRAVEL & ACTIVITY.
