## 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
  - object - tree(s)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - weather condition - crosswind (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - landing gear,main gear - separation (cause)
  - directional control - not maintained, pilot in command (contributing factor)

## Analysis

DURING TAKE-OFF THE PILOT DID NOT COMPENSATE FOR A STRONG CROSSWIND AND ALLOWED THE AIRCRAFT TO DRIFT SIDEWAYS WHERE THE MAIN GEAR COLLIDED WITH A FALLEN TREE SEPARATING IT FROM THE AIRCRAFT AND CAUSING THE AIRCRAFT TO VEER AND COLLIDE WITH THE GROUND.

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.
