## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL DURING THE LANDING ROLLOUT.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
- On ground/water encounter with terrain/water, landing - roll

## Analysis

N8528D WAS STOLEN FROM THE CUSTER AIRPORT. THE WRECKAGE WAS FOUND BY AN ANONYMOUS PERSON AT THE EDGEMONT AIRPORT. THE AIRPLANE HAD SUSTAINED DAMAGE TO THE LEFT WING AND LEFT LANDING GEAR. THE IDENTITY/QUALIFICATIONS OF THE PILOT ARE UNKNOWN. TIRE AND PROPELLER MARKS FOUND ON THE RUNWAY INDICATE THE AIRPLANE MADE A WHEEL LANDING AND GROUNDLOOPED.
