## Probable cause

WRONG RUNWAY SELECTION BY THE PILOT, RESULTING IN AN OVERRUN AND A COLLISION WITH A FENCE DURING LANDING ROLL. THE PREVAILING TAILWIND, RUNWAY INFORMATION AND MARKINGS, AND THE PILOT'S FAILURE TO USE THE PROPER TOUCHDOWN POINT ARE FACTORS.

## Sequence of events

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

- Overrun, landing - roll
  - weather condition - tailwind (contributing factor)
  - weather condition - tailwind
  - wrong runway - selected, pilot in command (cause)
  - facility,inadequate manuals/directives, airport personnel (contributing factor)
  - terrain condition - soft
- On ground/water collision with object, landing - roll
  - object - fence

## Analysis

THE PRIVATE PILOT LANDED MIDFIELD WITH A GUSTING TAILWIND. THE PLANE WAS UNABLE TO STOP ON THE 3,000 FOOT ASPHALT RUNWAY, AND OVERRAN INTO A SOFT TERRAIN. THE PLANE WAS DAMAGED WHEN IT RAN THROUGH A FENCE AND THE NOSE GEAR COLLAPSED IN THE SOFT TERRAIN. THE FIREWALL WAS BENT. THE PILOT SAID HE FLEW THE TAIL WIND LANDING BECAUSE HE HAD READ A SIGN ON THE AIRPORT WARNING OF 'LEGAL' CONSEQUENCES OF LANDING ON OTHER THAN RUNWAY 32, WHICH HE TOOK TO MEAN REGARDLESS OF WIND DIRECTION.

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.
