## Probable cause

The pilot's failure to maintain compensation for the wind conditions. A factor was the gusting tailwind.

## Sequence of events

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

- Loss of control - on ground/water, taxi - to takeoff
  - weather condition - tailwind (contributing factor)
  - weather condition - gusts (contributing factor)
  - compensation for wind conditions - not maintained, pilot in command (cause)
- Nose over, taxi - to takeoff

## Analysis

The pilot was back taxiing for departure on Runway 18 (2700 feet by 60 feet, dry/asphalt.  The pilot stated that, as he taxied near the area adjacent to the hangers on the east side of the runway, the aircraft turned abruptly to the right.  The pilot applied full left rudder and the aircraft nosed over and came to rest in an inverted attitude.  A weather report, for a reporting station located 25 miles and 28 degrees magnetic from the accident site, reported winds from 100 degrees magnetic at 16 knots gusting to 23 knots.
