Factual Information

On February 2, 2004, approximately 1630 central standard time, a Piper PA-28-235 single-engine airplane, N8936W, owned and operated by a private individual, was substantially damaged following a loss of control while landing in a pasture near Knox City, Texas. The private pilot, who was the sole occupant, was not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the Title 14 Code of Federal Regulations Part 91 personal flight. The flight originated from Terrell Municipal Airport (TRL) near Terrell, Texas, at approximately 1430, with Knox City as its intended destination. According to the 194-hour pilot, who was attempting to land in an open field at his ranch, at approximately 1430, after receiving weather information from Fort Worth Center, he departed Terrell Municipal Airport with the intent to land at his ranch located 8 miles west of Knox City. When the pilot arrived at the area where he planned to land, he peformed a fly-by to look for any obstructions in the field. The field appeared to be flat and open and the pilot executed a normal descent and landing. The pilot added that he properly flared the airplane and touched down on the main gear, with the nose gear touching down approximately 30 feet later. The pilot added that after firmly on the ground, he pulled all power and the aircraft rolled approximately 300 feet. According to the pilot, the aircraft then veered to the left and he applied right rudder, but the pilot was not able to stop the left turn. The pilot stated that approximately 30 feet later, the right wing impacted the ground and the nose gear collapsed. The aircraft spun around and then the left wing and propeller impacted the ground. The pilot stated that the ground was "soft," and the left main tire appeared to have sunk into the soft ground. Examination by an FAA inspector, who responded to the accident site, revealed that the left wing forward spar was fractured and the aft spar was bent. Further examination revealed that the forward section of the left wing root separated from the fuselage. The nose gear was found folded inside the wheel well.

Probable Cause and Findings

The pilot's attempt to land on terrain not suitable for landing. A contributing factor was the soft terrain.
