## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE AFTER AN ABORTED LANDING, WHICH RESULTED IN THE AIRPLANE COLLIDING WITH A MOUND OF DIRT OFF THE RUNWAY.

## Sequence of events

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

- In flight collision with object, landing - aborted
  - object - other (cause)
  - directional control - not maintained, pilot in command (cause)
  - flight controls - improper use of, pilot in command (cause)
  - remedial action - not possible, pilot in command (contributing factor)

## Analysis

THE PILOT LANDED HIS HOMEBUILT AIRPLANE ON RUNWAY 25.  AFTER TOUCHDOWN, HE FELT HE 'WAS NOT TOTALLY LINED UP' ON THE RUNWAY, SO HE INITIATED A GO-AROUND.  THE AIRPLANE DEPARTED THE LEFT SIDE OF THE RUNWAY AT APPROXIMATELY THE HALFWAY POINT, BECAME AIRBORNE, AND FAILED TO CLEAR A MOUND OF DIRT WHICH WAS ABOUT 15 FEET HIGH AND LOCATED APPROXIMATELY 125 FEET AWAY.  IT NOSED OVER AND CAME TO REST INVERTED ON THE FAR SIDE OF THE MOUND.
