As the pilot was landing the helicopter on a gravel bar on a bank of the Spokane River, a main rotor blade contacted the bank. The helicopter dropped and tumbled onto the rocks. The pilot reported that there were no preimpact mechanical malfunctions. According to records kept by the Federal Aviation Administration (FAA), the pilot was operating a restricted-category aircraft on a personal flight. Also, the pilot's FAA Third Class Medical Certificate had expired about 8 months prior to the accident.
Probable Cause: The pilot's selection of an unsuitable landing site, and his failure to maintain rotor blade clearance from terrain during landing.
