On August 26, 1995, at 1900 central daylight time, a Cessna 206, N5088U was substantially damaged during a hard landing near Whitesboro, Texas. The private pilot/owner and one passenger were not injured and the other passenger sustained minor injuries. The airplane departed Hillsboro, Texas, at 1825 for the Title 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed and a flight plan was not filed. The pilot reported to a Federal Aviation Administration (FAA) inspector that, during the landing roll at a private sod airstrip, the nose wheel collapsed and the left wing tip contacted the ground. Repeated attempts to obtain a completed Pilot/Operator Report (NTSB Form 6120.1/2) were unsuccessful. During a telephone interview conducted by the investigator-in- charge, the right front seat passenger reported that the airplane landed "hard" and she hit her head on the instrument panel. The witness was mailed a Passenger Statement (NTSB Form 6120.9), but did not return it. An FAA inspector examined the airplane and reported that the nose wheel fork was separated from the nose landing gear strut. The left wing was bent upward 15 to 20 degrees approximately 2 feet inboard from the wing tip and the outboard 2 feet of the leading edge were crushed aft.
