## Probable cause

The pilot's failure to maintain directional control during the takeoff ground roll.   A tailwind was a factor.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - aircraft control - not maintained, pilot in command (cause)
  - weather condition - tailwind (contributing factor)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - ground

## Analysis

The pilot reported that during a downwind takeoff on runway 13, as he raised the tail of the aircraft, the wind pushed the aircraft up and to the left, pushing him off of the runway. While attempting to correct, the aircraft ground looped.  The winds were reported from 340 degrees at eight knots.  The pilot reported no mechanical failures or malfunctions with the aircraft at the time of the accident.
