## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
- In flight collision with terrain/water, landing - aborted
  - terrain condition - grass (contributing factor)

## Analysis

THE PILOT WAS FAMILIARIZING HIMSELF WITH THIS TYPE OF AIRCRAFT AND WAS MAKING A FULL FLAP LANDING. HE ALLOWED THE AIRCRAFT TO DRIFT LEFT DURING THE LANDING ROLL IN A SLIGHT CROSSWIND. HE THEN ATTEMPTED TO ABORT THE LANDING ROLL WITH THE APPLICATION OF TAKEOFF POWER.  BEING UNFAMILIAR WITH THE AIRCRAFT, HE ALLOWED THE ENGINE TORQUE TO FORCE IT STILL FURTHER LEFT AND OFF THE RUNWAY WHERE IMPACT WITH THE TERRAIN OCCURRED.

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.
