Aircraft Accident/Incident Report

Greenacres, Washington 99016
Monday, August 7, 2006 15:30 PDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, "after landing, braking action was very poor due to a heavily irrigated section of runway 16 from mid-field to the departure end." The airplane's tires "appeared to hydroplane" on the wet grass runway surface, and the pilot was unable to stop the airplane from overrunning the end of the runway and striking a fence. An FAA inspector examined the airplane and reported that the bottom wing skin was torn and one aileron had a hole punctured in it. The pilot commented that the accident could have been prevented by "more close monitoring of the runway watering system" and "a physical check of the entire runway before takeoff to determine any variances in surface condition."

NTSB Probable Cause Narrative

The pilot's selection of an unsuitable landing runway which resulted in a runway overrun and collision with a fence. A contributing factor was the wet runway condition.
