## Analysis

THE 2500 FT RUNWAY HAD TREES ON 3 SIDES. THE NORMAL PATTERN FOR LANDING WAS FROM EAST TO WEST AND DEPARTURES WERE NORMALLY FROM WEST TO EAST. A LONG, SHALLOW, TAILWIND APPROACH WAS MADE FROM THE EAST AT ABOUT 65 KNOTS. THE PILOT USED 40 DEGREES OF FLAPS AND MAINTAINED ABOUT 1400 TO 1500 RPM UNTIL AFTER LANDING. IMMEDIATELY, HE REALIZED HE HAD TOO MUCH SPEED AND CHOPPED HIS POWER. THE AIRCRAFT HIT A DIP AND LIFTED OFF THE RUNWAY. BY THIS TIME, THE PILOT WAS COMMITTED TO THE LANDING, BUT WAS UNABLE TO STOP ON THE RUNWAY. HE CONTINUED OFF THE RUNWAY AND COLLIDED WITH TREES. THE PROCEDURE FOR A SHORT FIELD LANDING WITH FULL FLAPS (40 DEGREES) IS TO HOLD 60 KNOTS UNTIL THE FLARE, REDUCE POWER TO IDLE AFTER CLEARING OBSTACLES, TOUCH DOWN ON MAIN WHEELS FIRST, APPLY HEAVY BRAKES, AND RETRACT THE FLAPS.

## Sequence of events

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

- Overrun, landing - roll
  - terrain condition - high obstruction(s) (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (contributing factor)
  - weather condition - tailwind (contributing factor)
  - airspeed - excessive, pilot in command (cause)
  - procedures/directives - not followed, pilot in command (cause)
  - raising of flaps - not performed, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - tree(s) (contributing factor)
