## Probable cause

The pilot's failure to maintain directional control during an aborted takeoff.  Factors include a tailwind gust, and a large rock near the side of the runway.

## Sequence of events

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

- On ground/water collision with object, takeoff - aborted
  - directional control - not maintained, pilot in command (cause)
  - weather condition - gusts (contributing factor)
  - weather condition - unfavorable wind (contributing factor)
  - terrain condition - rock(s)/boulder(s) (contributing factor)

## Analysis

During the takeoff roll, the aircraft unexpectedly encountered a tailwind gust. This resulted in the aircraft veering toward the side of the runway, so the pilot aborted the takeoff. During the abort sequence, the pilot was unable to maintain directional control, and the aircraft departed the side of the runway and impacted a nearby large rock.
