## Sequence of events

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

- In flight collision with object, takeoff - initial climb
  - terrain condition - soft (contributing factor)
  - wrong runway - selected, pilot in command (contributing factor)
  - lift-off - premature, pilot in command (contributing factor)
  - aborted takeoff - not performed, pilot in command (cause)
  - object - tree(s) (contributing factor)
  - stall/mush - uncontrolled, pilot in command (contributing factor)

## Analysis

THE PILOT STATED THAT THE AIRCRAFT WAS SLOW TO GAIN NORMAL LIFT-OFF SPEED DUE TO THE SURFACE OF THE AIRSTRIP. HE ALSO STATED THAT AFTER PREMATURELY VAULTING THE AIRCRAFT INTO THE AIR THE AIRCRAFT NEVER GAINED SUFFICIENT AIRSPEED FOR A CLIMB. THE AIRCRAFT MUSHED INTO TREES OFF THE END OF THE RUNWAY. RUNWAY 9-27 WAS OVER 900 FT LONGER THAN THE ONE SELECTED AND WAS AVAILABLE FOR USE.

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.
