## Sequence of events

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

- Overrun, takeoff
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - aborted takeoff - delayed, pilot in command (cause)
- On ground/water collision with object, takeoff
  - ground loop/swerve - intentional, pilot in command
  - object - tree(s) (contributing factor)

## Analysis

THE PILOT WAS TAKING OFF ON THE FIRST FLIGHT OF THE DAY WITH A REPORTED LOAD OF 1080 LBS OF WHEAT SEED. DURING THE TAKEOFF, THERE WAS A DIRECT CROSSWIND OF 6 KTS AND THE TEMPERATURE AND DEW POINT WERE 78 AND 68 DEG, RESPECTIVELY. AFTER USING ABOUT 3/4 OF THE RUNWAY, THE PILOT BECAME AWARE THAT HE WAS A NOT GOING TO GET AIRBORNE IN SUFFICIENT TIME TO CLEAR A LINE OF TREES. HE ACTIVATED THE EMERGENCY DUMP LEVER, BUT THE SYSTEM WAS PROGRAMMED TO DUMP ONLY 1.5 BUSHELS PER ACRE. TO AVOID RUNNING INTO THE LINE OF TREES, THE PILOT INTENTIONALLY GROUND LOOPED THE PLANE, BUT IT CONTINUED INTO THE TREES WHILE MOVING BACKWARD.

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.
