## Probable cause

WRONG RUNWAY SELECTED BY SECOND PILOT. FACTORS WERE: TAILWIND AND INADEQUATE SUPERVISION BY PILOT-CFI.

## Sequence of events

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

- Overrun, landing - roll
  - wrong runway - selected, copilot/second pilot (cause)
  - weather condition - tailwind (contributing factor)
  - supervision - inadequate, pilot in command(cfi)
  - aborted takeoff - performed, pilot in command(cfi)
- On ground/water collision with object, landing - roll
  - object - fence
- On ground/water collision with object, takeoff - aborted
  - object - fence

## Analysis

THE PILOT COMMENCED A DOWNWIND TAKEOFF. AN UNSATISFACTORY RATE OF CLIMB AND A LEFT DRIFT WERE NOTED UPON LIFTOFF. THE PILOT UNDER TRAINING REQUESTED ASSISTANCE FROM THE INSTRUCTOR PILOT. AN ATTEMPT WAS MADE TO REJECT THE TAKEOFF. INSUFFICIENT RUNWAY REMAINED TO STOP THE AIRPLANE WHICH DEPARTED THE END OF THE RUNWAY, TRAVERSED A FIELD, CROSSED A ROAD, STRUCK A FENCE THEN CAME TO REST INVERTED.
