Probable cause

The pilot's inadequate compensation for wind conditions. A factor associated with this accident was a crosswind.

Analysis

The pilot was landing to the south on a remote beach adjacent to Bristol Bay. He reported that wind conditions at the time of the accident were about 090 degrees at 15 knots, with peak gusts to 20 knots. He stated that as the airplane touched down, it veered to the right. He attempted to abort the landing by applying full power and full left aileron, but the airplane became airborne, veered to the right over the tidal surf, and collided with a large wave. The airplane sank, and the four occupants swam about 50 yards to shore. He said there were no preaccident mechanical anomalies with the airplane.

Factual narrative

On June 6, 1998, about 1215 Alaska daylight time, a Cessna 172 airplane, N8092B, sustained substantial damage after colliding with ocean surf, about 25 miles south of Naknek, Alaska. The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14 CFR Part 91 when the accident occurred. The pilot/airplane owner and three passengers aboard were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated at the Naknek Airport, about 1200.
