## Probable cause

DIRECTIONAL CONTROL NOT MAINTAINED BY THE PILOT. UNFAVORABLE WIND, HIGH WIND, AND GUSTS WERE CONTRIBUTING FACTORS.

## 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 - unfavorable wind (contributing factor)
  - weather condition - high wind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - uncontrolled
- Nose over, landing

## Analysis

ACCORDING TO THE PLT, THE WIND SOCK INDICATED THERE WAS LITTLE WIND BEFORE HE LANDED. HE RPRTD THAT AFTER LANDING ON RWY 7, THE WIND SHIFTED & A GUST BLEW THE ACFT TO THE RIGHT. SUBSEQUENTLY, THE ACFT WENT OFF THE RIGHT SIDE OF THE RWY & NOSED OVER. WITNESSES RPRTD THE WIND WAS VARIABLE & GUSTY AT THE TIME OF THE ACDNT.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).
