Analysis

The pilot was landing his aircraft on a very wet 1,170 foot grass runway. The pilot was not able to stop the aircraft before it collided with a fence at the end of the runway. According to the manufacturers performance figures, under the given temperature and wind conditions, the runway length required on dry grass would be 740 feet. Although not addressed in the pilot operators handbook, due to the extreme variables, Cessna aircraft company engineers stated that wet grass would increase the landing distance 100 to 300%.
