## Probable cause

WRONG RUNWAY SELECTED AND ABORTED TAKEOFF DELAYED BY THE PILOT IN COMMAND.

## Sequence of events

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

- Overrun, takeoff - aborted
  - terrain condition - grass (contributing factor)
  - terrain condition - wet (contributing factor)
  - weather condition - tailwind (contributing factor)
  - wrong runway - selected, pilot in command (cause)
  - aborted takeoff - delayed, pilot in command (cause)
- On ground/water collision with object, takeoff - aborted
- Nose over, takeoff - aborted
  - object - fence (contributing factor)

## Analysis

THE PVT PLT SAID THAT HE WAS ATTEMPTING TO TAKEOFF TO THE SOUTH, BUT WAS UNABLE TO REACH FLYING SPEED AND ABORTED THE TAKEOFF. UNABLE TO STOP, THE ACFT CONTINUED OFF THE ASPHALT ONTO THE WET GRASS OVER-RUN, STRUCK A FENCE AND OVERTURNED. A WITNESS AND THE NEAREST WEATHER REPORTING STATION SAID THE WIND WAS OUT OF THE NORTHWEST.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
