## Sequence of events

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

- Overrun, landing - roll
  - distance - misjudged, pilot in command (cause)
  - airspeed - misjudged, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE PILOT-IN-COMMAND (PIC) WAS REFAMILIARIZING HIMSELF IN THE PIPER PA-18. HE WAS OCCUPYING THE FRONT SEAT WHILE THE OWNER WAS ACTING AS SECOND-IN-COMMAND IN THE BACKSEAT. ON THE THIRD LANDING, THE AIRCRAFT ENCOUNTERED SOFT TERRAIN TOWARDS THE END OF THE ROLL-OUT. THE PIC STATED THAT APPLICATION OF BRAKES COMPOUNDED THE PROBLEM WITH THE WHEELS DIGGING IN, RESULTING IN A NOSE OVER. IN A TELEPHONE CONVERSATION, THE PIC ADMITTED THAT THE APPROACH WAS HIGH AND FAST AND THAT HE OVERSHOT THE PLANNED TOUCHDOWN POINT. THE OWNER STATED THAT THE AIRCRAFT WAS EQUIPPED WITH OVERSIZE TIRES AND CLEVELAND BRAKES.
