Sequence of events

Analysis

The pilot reported that, as he made the approach over a river to land at his private airstrip, he "came in too low and hit a dock." The airplane's propeller struck the dock, and the landing gear separated from the airplane, which then slid about 25 ft and came to a stop. The airplane sustained substantial damage to the engine mounts. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
