## Sequence of events

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

- Loss of control - in flight, landing - roll
  - weather condition - tailwind (contributing factor)
  - proper climb rate - selected, pilot in command (contributing factor)
  - airspeed - misjudged, pilot in command (cause)
  - distance - misjudged, pilot in command (cause)
  - aborted landing - not selected, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - go-around - intentional, pilot in command (contributing factor)

## Analysis

THE ACFT GROUND-LOOPED DURING LANDING ON A 2000 FOOT GRAVEL RUNWAY. THE PILOT STATED THAT AS HE APPROACHED RUNWAY 8 HIS AIRSPEED WAS TOO HIGH AND HE ALSO WAS DRIFTING TO THE RIGHT. DURING TOUCHDOWN HE LOST DIRECTIONAL CONTROL AND ALLOWED THE ACFT TO CONTINUE TO GROUNDLOOP TO AVOID A 5 FOOT DROP AT THE RUNWAYS END. THE WIND WAS FROM 270 DEGREES AT 8 KTS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
