## Probable cause

The pilot's failure to maintain aircraft control during a go-around.  A quartering tailwind was a factor.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - aircraft control - not maintained, pilot in command (cause)
  - weather condition - tailwind (contributing factor)
- In flight collision with terrain/water, go-around (vfr)
  - terrain condition - ground

## Analysis

Due to the pilot's injuries, he does not recall the landing event, however, witnesses in the area reported that the aircraft was landing on runway 14 with a quartering tailwind.  The witnesses observed the aircraft "tipping from one wheel to the other," and "bouncing back and forth on its wheels and swerving."   The aircraft then lifted off and "flew across the road, rocking side to side then from 30 feet went nose down by the tracks in a ditch."  The aircraft came to rest nose down to the ground about 430 feet from the end of runway 14.  The nearest weather reporting facility located 19 nautical miles northwest of the accident site was reporting a wind from 260 degrees at 14 knots, gusting to 18 knots.

## Factual narrative

On April 17, 2006, at 1400 Pacific daylight time, a Cessna 170B, N2288D, registered to and operated by the pilot as a 14 CFR Part 91 personal flight, collided with the terrain during an attempted go-around at River Lake Airstrip, Clark Fork, Idaho.  Visual meteorological conditions prevailed at the time and a visual flight rules flight plan was filed.  The aircraft was substantially damaged and the student pilot, the sole occupant, was seriously injured.  The flight departed from Bonners Ferry, Idaho, about 30 minutes prior to the accident.
