## Probable cause

THE PILOT NOT ATTAINING THE PROPER TOUCHDOWN POINT BECAUSE OF EXCESSIVE ALTITUDE AND AIRSPEED, AND THE PILOT'S FAILURE TO PERFORM A GO-AROUND. A FACTOR IN THIS ACCIDENT WAS THE ROUGH AND UNEVEN TERRAIN WHICH WAS ENCOUNTERED AFTER THE AIRCRAFT DEPARTED THE RUNWAY.

## Sequence of events

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

- Overrun, landing - roll
  - proper touchdown point - not attained, pilot in command (cause)
  - altitude - excessive, pilot in command (cause)
  - airspeed(vref) - excessive, pilot in command (cause)
  - in-flight planning/decision - poor, pilot in command
  - go-around - not performed, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

3THE PILOT AND CO-PILOT REPORTED IN THEIR WRITTEN STATEMENTS THAT THE AIRPLANE WAS ABOVE GLIDESLOPE ON THE FINAL APPROACH.  THEY SAID THE AIRPLANE TOUCHED DOWN ABOUT 1,500 FEET FROM THE APPROACH END OF THE 4,700 FEET LONG RUNWAY. THE PILOT SAID HE APPLIED THE BRAKES BUT COULD NOT STOP THE AIRPLANE ON THE RUNWAY.  THE AIRPLANE DEPARTED THE END OF THE RUNWAY AND CONTINUED FORWARD OVER ROUGH AND UNEVEN TERRAIN.  THE MAIN LANDING GEAR SHEARED OFF AND PENETRATED BOTH WINGS.  THE AIRPLANE CAME TO A STOP IN A GULLY.  OTHER WITTNESSES LOCATED ON THE GROUND AND IN THE AIR TRAFFIC CONTROL TOWER REPORTED THE AIRPLANE WAS 'HIGH AND FAST' AND TOUCHED DOWN AT ABOUT MIDFIELD OR AFTER.
