The NTSB's narrative final · quoted from the NTSB record
During the approach, the pilot landed long. He evaluated the remaining runway, determined it was sufficient to stop the airplane, and decided to continue the landing. The airplane overran the end of the runway, impacted a small ditch, crossed a road, and came to rest upright in a larger ditch. During the runway overrun, the airplane sustained substantial damage to the lower fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
