## Probable cause

THE PILOT'S IMPROPER COMPENSATION FOR WIND CONDITIONS AND HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL.  FACTORS WERE: A CROSSWIND AND TAILWIND COMPONENT.

## 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 - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - weather condition - tailwind (contributing factor)
- Dragged wing,rotor,pod,float or tail/skid, landing - roll
- Main gear collapsed, landing - roll

## Analysis

PRIOR TO THE FIRST LANDING ON RUNWAY 17L, ATIS REPORTED THE WIND TO BE FROM 180 DEGREES AT SEVEN KNOTS.  PRIOR TO HIS SECOND LANDING, THE CONTROL TOWER TOLD THE PILOT THE WIND WAS FROM 050 DEGREES AT SIX KNOTS.  THEY REQUESTED THAT HIS THIRD LANDING BE MADE TO A FULL STOP.  THE PILOT SAID THAT DURING THE THIRD LANDING ROLLOUT, THE RIGHT WING LIFTED AND HE CORRECTED WITH FULL RIGHT AILERON AND FULL LEFT RUDDER WITH BRAKE, BUT COULD NOT MAINTAIN DIRECTIONAL CONTROL.  THE LEFT WING CONTACTED THE RUNWAY AND THE LEFT MAIN LANDING GEAR COLLAPSED.  THE PILOT ESTIMATED THE WINDS WERE THEN FROM THE SOUTHWEST AT 15 KNOTS.  THE OFFICIAL WIND RECORDED ONE MINUTE AFTER THE ACCIDENT WAS 220 DEGREES AT 15 KNOTS.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
