## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Dragged wing,rotor,pod,float or tail/skid, landing
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)

## Analysis

THE PILOT REPORTED HE WAS LANDING ON SOD RUNWAY 27 WITH A GUSTY CROSSWIND FROM 300 DEGREES. HE WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL, AND THE AIRPLANE GROUND LOOPED.  THE PILOT LISTS 2.2 HOURS TOTAL FLIGHT EXPERIENCE IN THE WORLD WAR TWO VINTAGE AIRPLANE AT THE TIME OF THE ACCIDENT. NO PREACCIDENT MECHANICAL ANOMALY WAS DISCOVERED OR CLAIMED.

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.
