Probable cause

Inadequate compensation for wind conditions by the pilot, which resulted in a loss of directional control. A factor related to the accident was: the gusty crosswind condition.

Analysis

The air taxi pilot was on an unscheduled charter flight in an amphibian airplane to pick up passengers near hagemeister island. He elected not to land at hagermeister island due to water conditions, but flew instead to a nearby airstrip for a wheel landing. He said that during the landing roll, a gust of wind caused the right wing to lift and he was unable to maintain directional control. The airplane went off the left side of the runway and the left wing was damaged.
