## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRCRAFT. THE EXISTING WIND CONDITIONS AND THE DITCH THAT WAS LOCATED NEAR THE RUNWAY WERE FACTORS IN THE ACCIDENT.

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

## Analysis

THE PILOT ELECTED TO LAND ON A 3 1/2 PERCENT (ABOUT 2 DEGREES) UP SLOPING RUNWAY WITH A WIND GUSTING TO 16 KNOTS IN THE DIRECTION OF LANDING. AFTER THE AIRCRAFT SLOWED DURING THE LANDING, IT TURNED LEFT INTO AN OPEN DITCH.
