The pilot was landing the tailwheel equipped airplane in a crosswind on runway 20 and reported that during the landing roll, "...a sudden gust from the west lifted the right wing and landing gear."

The airplane received structural damage to left wing and fuselage. The wind at the time of the accident was from 110 degrees at 10 knots. No mechanical malfunctions were reported.

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