## 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
  - fluid,hydraulic - low level (cause)
  - landing gear,normal brake system - inoperative (cause)
  - directional control - not possible, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - dirt bank/rising embankment (contributing factor)
- Nose over, landing - roll

## Analysis

AS THE AIRCRAFT SLOWED DURING THE LANDING ROLL, IT BEGAN TO DRIFT RIGHT WHEN THE RUDDER BECAME INEFFECTIVE. THE PILOT WAS UNABLE TO OBTAIN LEFT BRAKING ACTION TO MAINTAIN DIRECTIONAL CONTROL. SUBSEQUENTLY, THE RIGHT MAIN GEAR STRUCK A SMALL EARTH BANK AND THE PLANE NOSED OVER. THE PILOT REPORTED THAT THE FLUID LEVEL WAS TOO LOW TO ACTUATE THE BRAKE.

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.
