## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - weather condition - high density altitude (contributing factor)
  - aborted takeoff - delayed, pilot in command (cause)
  - terrain condition - high obstruction(s) (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - performance data - not identified, pilot in command (cause)
- Nose gear collapsed, landing - flare/touchdown
  - landing gear,nose gear assembly - overload (contributing factor)
- Nose over, landing - roll

## Analysis

THE ACFT MADE A HARD LANDING DURING AN ABORTED TAKEOFF. THE PILOT STATED THAT AFTER TAKEOFF HE THOUGHT HE COULD NOT CLEAR THE TREES AT THE DEPARTURE END OF THE RWY. HE CLOSED THE THROTTLE AND ATTEMPTED TO RE-LAND HIS ACFT. DURING TOUCHDOWN ON THE ROUGH DIRT ROAD BEING USED AS A RWY THE NOSE GEAR COLLAPSED AND THE ACFT NOSED OVER. MAX ALT DURING TAKEOFF WAS 15 FT AGL. THE DENSITY ALT WAS ABOUT 6600 FT.

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.
