## Probable cause

THE STUDENT PILOT'S DELAYED DECISION TO ABORT THE TAKEOFF, RESULTING IN HIS INABILITY TO STOP THE AIRPLANE IN THE REMAINING RUNWAY. FACTORS WERE THE PILOT'S LACK OF TOTAL FLYING EXPERIENCE, AND THE HIGH OUTSIDE AIR TEMPERATURE AT THE TIME OF THE ACCIDENT.

## Sequence of events

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

- Overrun, takeoff - aborted
  - weather condition - temperature extremes (contributing factor)
  - aborted takeoff - delayed, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
- On ground/water collision with object, takeoff - aborted
  - object - tree(s)

## Analysis

THE STUDENT PILOT WAS PERFORMING THE TAKEOFF OF THE RETURN LEG OF A VFR CROSS COUNTRY FLIGHT. AT ABOUT 55-60 KNOTS, HE BEGAN TO ROTATE, AND THE STALL WARNING HORN ACTIVATED. THE AIRPLANE WAS NOT REACHING FLYING AIRSPEED, SO HE REDUCED THE THROTTLE AND APPLIED BRAKES. HE WAS UNABLE TO BRING THE AIRPLANE TO A STOP IN THE REMAINING RUNWAY SURFACE, AND THE AIRPLANE COLLIDED WITH A TREE AND A CREEK BED. THE PILOT REPORTED NO MECHANICAL PROBLEMS WITH THE AIRPLANE, AND NONE WERE FOUND DURING THE POST ACCIDENT INSPECTION. THE PILOT, WHOSE TOTAL FLYING TIME WAS 21 HOURS, REPORTED THE TEMPERATURE AT TAKEOFF TO BE ABOUT 100 DEGREES F.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
