He checked the wind sock before landing, and it was "flaccid," indicating calm wind. He slowed the airplane to 80 mph on final approach and landed near the approach end of the runway, which was 2,355 ft long. He estimated that the airplane should have rolled to a stop; however, it continued down the runway despite heavy braking. The airplane departed the end of the runway, traveled across a small road and down an embankment, and came to rest in water at the edge of the airport boundary. A Federal Aviation Administration inspector examined the wreckage and reported that the airplane sustained substantial damage to the forward fuselage and submersion in salt water. There were tire skid marks on the runway leading to the wreckage. A weather buoy, located about 1 mile east of the airport, recorded wind from the west about the time of the accident, which would have resulted in a tailwind of up to 8 knots. The pilot reported there were no preimpact mechanical malfunctions or anomalies with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that the takeoff, climb, and en route portions of the cross-country flight were uneventful.
