## Probable cause

THE PROPER TOUCHDOWN POINT WAS NOT ATTAINED AND THE PILOT FAILED TO PERFORM A GO AROUND.  A FACTOR RELATED TO THE ACCIDENT WAS THE TAILWIND CONDITION IN WHICH THE PILOT WAS ATTEMPTING TO LAND.

## 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)
  - wrong runway - selected, pilot in command (cause)
  - proper touchdown point - not attained, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
- Nose over, landing - roll

## Analysis

THE PILOT SAID THAT WHILE ON FINAL APPROACH, FOR LANDING, HE FELT HE WAS TOO HIGH. HE DECIDED TO LAND ANYWAY, AND WAS UNABLE TO STOP ON THE REMAINING RUNWAY.  THE AIRCRAFT LEFT THE END OF THE RUNWAY AND NOSED OVER. HE WAS ATTEMPTING TO LAND WITH A QUARTERING TAILWIND.
