NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The commercial certificated pilot was landing a tundra tire equipped airplane on a gravel runway. The winds were light and variable. The pilot said that during the landing roll, just before the tailwheel touched the runway, a wind gust pushed the tail of the airplane to the right. A second gust of wind then pushed the tail to the left. The pilot said he was unable to fully control the direction of the airplane, and decided to add engine power and abort the landing. The airplane veered to the left and the left main wheel contacted the surface of a tidal slough. The right wing then struck the surface of the slough, and the airplane inverted in about five feet of water. Both occupants of the airplane exited the airplane from underwater. The airplane received damage to both wings and the propeller.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain directional control of the airplane. A factor in the accident was an inadvertent ground swerve.
