## Probable cause

PILOT DID NOT MAINTAIN AN ADEQUATE AIRSPEED AFTER TAKEOFF WHICH RESULTED IN A LOSS OF CONTROL AND ABORTED TAKEOFF. THE PILOT DID NOT MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE AND DID NOT PROPERLY CORRECT THE SITUATION BEFORE COLLIDING WITH TREES AND A FENCE.

## Sequence of events

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

- Loss of control - in flight, takeoff - aborted
  - directional control - not maintained, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
  - remedial action - improper, pilot in command (cause)
- Forced landing, descent - uncontrolled
- On ground/water collision with object, landing - roll
  - object - fence (contributing factor)
  - object - tree(s) (contributing factor)

## Analysis

DURING THE TAKEOFF ROLL WITH 15 DEGREES OF FLAPS, THE AIRPLANE HAD ACCELERATED TO 60 MPH WHEN THE PILOT EXTENDED THE FLAPS TO 25 DEGREES FOR THE SHORT FIELD TAKEOFF. THE AIRPLANE BECAME AIRBORNE AND THE PILOT LOWERED THE NOSE AND NOTED HE WAS 5 DEGREES OFF THE CENTERLINE TO THE LEFT. THE PILOT OVER CORRECTED TO 5 DEGREES TO THE RIGHT OF CENTER LINE AND WAS HEADING DIRECTLY TOWARDS TREES. AT THIS POINT, THE AIRPLANE WAS APPROACHING A STALL. THE PILOT OPTED TO ABORT THE TAKE OFF AND REDUCED POWER. THE AIRPLANE WAS STILL HEADING FOR TREES AND THE PILOT TRIED TO MANEUVER AROUND THEM; HOWEVER, THE AIRPLANE TRAVELED OFF THE AIRSTRIP THROUGH A BARBED WIRE FENCE AND ONTO A PUBLIC ROAD THAT PARALLELED THE RUNWAY. THE AIRPLANE SLID DOWN THE ROAD AND CAME TO REST TOWARDS THE END OF THE RUNWAY.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
