Probable cause

The failure of the pilot to land at the proper touchdown point and the resulting hard landing. Damage to the airplane precluded a go-around and resulted in the intentional swerve into a River to avoid injuries to people on the ground.

Analysis

The airplane was landed long on an unimproved strip. It touched down hard which resulted in the propeller striking the ground. A go-around was attempted unsuccessfully because of insufficient thrust from the damaged propeller. The pilot intentionally swerved the airplane into the adjacent River to avoid people & equipment on the FAR end of the strip.
