## Probable cause

AIRCRAFT CONTROL WAS NOT MAINTAINED BY THE PILOT.  FACTORS RELATED TO THE ACCIDENT WERE A QUARTERING TAILWIND.

## 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)
- Nose over, takeoff - roll/run

## Analysis

THE PILOT SAID THAT WHILE ATTEMPTING TO TAKEOFF, HE RAISED THE TAIL AND THE AIRCRAFT CONTINUED TO NOSE DOWN UNTIL THE PROPELLER STRUCK THE RUNWAY AND AIRCRAFT NOSED OVER.  THE TAKEOFF WAS ATTEMPTED WITH A  LIGHT, QUARTERING TAILWIND.
