## Probable cause

THE PILOT'S IMPROPER COMPENSATION FOR WIND CONDITIONS.  FACTORS RELATED TO THE ACCIDENT WERE: THE PILOT'S SELECTION OF THE WRONG RUNWAY AND THE RESULTANT TAILWIND CONDITION.

## Sequence of events

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

- Nose over, landing - roll
  - wrong runway - selected, pilot in command (contributing factor)
  - weather condition - tailwind (contributing factor)
  - compensation for wind conditions - improper, pilot in command (cause)

## Analysis

THE PILOT SAID THAT WHILE LANDING DOWNWIND ON A SOD STRIP, HE WAS UNABLE TO STOP THE AIRCRAFT AND IT FLIPPED INVERTED.
