## 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)
  - terrain condition - high obstruction(s) (contributing factor)
  - go-around - not performed, pilot in command
- Main gear collapsed, landing
  - landing gear,main gear - overload
  - ground loop/swerve - intentional, pilot in command

## Analysis

WHILE LANDING ON A 1600 FT AG STRIP, THE PLT REALIZED HE HAD TOO MUCH SPEED. HOWEVER, THERE WERE POWER LINES AT THE DEPARTURE END OF THE STRIP, SO HE ELECTED NOT TO ATTEMPT A GO-AROUND. HE INTENTIONALLY GROUND LOOPED THE ACFT TO AVOID A DITCH & ROAD AT THE END OF THE STRIP. DURING THE GROUND LOOP, THE RIGHT MAIN GEAR, RIGHT WING & STABILIZER WERE DAMAGED.
