## Probable cause

The pilot's failure to maintain directional control of the airplane during the landing roll.  A factor associated with the accident was the ditch.

## 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
  - directional control - not possible, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

The airplane veered to the right during the landing roll and the pilot was unable to maintain directional control.  The aircraft traveled through the grass and came to rest in a ditch.

## Factual narrative

The pilot stated that prior to the flight he added air to the front tire, which was slightly deflated.  The pilot reported that after takeoff he stayed in the traffic pattern and made three touch and go landing.  He then departed the area for a 45 minute local flight.  The pilot reported he returned to the airport and was landing on runway 22 when the accident occurred.  The pilot stated that shortly after touchdown the plane started to veer to the right. The pilot stated that he attempted to use left rudder to compensate, but the airplane continued to veer right off the runway and into the grass.  The pilot stated that the airplane came to rest in a ditch.
