## Probable cause

The pilot's failure to maintain directional control during landing which resulted in the airplane striking a dirt mound and nosing over.  The dirt mound was a factor.

## Sequence of events

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

- Loss of control - on ground/water, landing
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing
  - terrain condition - other (contributing factor)
- Nose over, landing

## Analysis

The biplane was substantially damaged when it nosed over during landing.  The pilot reported that the accident occurred on the third landing on his private airstrip.  He stated that on the third landing he decided to land in the opposite direction of the previous landings due to the position of the sun.  He stated that when he touched down, the airplane headed straight for a pile of dirt at the side of the runway.  The pilot stated that the locking tailwheel on the airplane is designed to keep the airplane heading straight.  He stated that he was not able to correct the airplane's path before hitting the dirt pile with the right main landing gear causing the airplane to nose over.

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.
