## Probable cause

FAILURE OF THE PILOT TO MAINTAIN PROPER RUNWAY ALIGNMENT.  THE SOFT TERRAIN WAS A RELATED FACTOR.

## Sequence of events

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

- Nose over, landing - roll
  - terrain condition - soft (contributing factor)
  - proper alignment - not maintained, pilot in command (cause)

## Analysis

THE PILOT WAS COMPLETING A LANDING, WHEN HE ALLOWED THE MAIN LANDING GEAR OF THE AIRCRAFT TO TRACK OFF THE HARD SURFACED RUNWAY & ONTO SOFT TERRAIN.  THE AIRCRAFT THEN NOSED OVER & WAS SUBSTANTIALLY DAMAGED.

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.
