On January 6, 1997, at 1600 central standard time, a Consolidated Aeronautics Inc. Lake LA-4-200, N6203V, registered to and operated by a private owner as a Title 14 CFR Part 91 personal flight, was substantially damaged during landing roll at Skyhaven Airport near Channelview, Texas. Visual meteorological conditions prevailed, and a flight plan was not filed. The private pilot, sole occupant of the airplane, was not injured. The flight originated from Skyhaven Airport, about 40 minutes before the accident. The pilot reported to the FAA inspector that during landing roll on runway 09, the aircraft drifted to the right side of the sod runway, and the nose landing gear sunk 6 to 8 inches into the soft ground. The nose landing gear sheared off, and the aircraft continued for 70 feet until it nosed over and came to a stop inverted. The pilot reported in the Pilot/Operator Accident Report that after landing, while taxiing on the runway to the hangar, a "severe wind shear deviated direction of taxi to a muddy portion of the runway. The nose wheel stuck in the mud causing tail of aircraft to become exposed to wind, which in turn blew aircraft over." The pilot also reported that the winds at the time of the accident were from 050 degrees at 11 knots. Examination of the aircraft by the FAA inspector revealed that the right wing spar was bent, and a rib running along the fuselage was fractured.
