NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The airplane was observed flying toward the west. One witness said, "The plane was low exceptionally low." The witness said they watched the airplane initiate a turn to the north. Another witness said, "It [the airplane] was low and slow and the turn was tight. As he looked like he was going to complete the turn, he went straight down." The witness said the airplane disappeared into the cornfield. The witness said she then saw dust and debris coming up from the field. Both witnesses estimated the airplane to be approximately 200 to 300 feet above the ground when it began to turn. An examination of the airplane wreckage revealed no anomalies. FAA toxicology revealed concentrations of PROPOXYPHENE and NORPROPOXYPHENE present in urine, NORPROPOXYPHENE and TRAMADOL (1.195 ug/mL, ug/g) detected in blood, and TRAMADOL detected in liver.

She said in the months prior to the accident, the pilot had become forgetful. The pilot's primary physician saw the pilot the day before the accident to follow up on a pulmonary embolism. The pilot's pulmonary doctor revealed that he had last seen the pilot 10 days before the accident for deep vein thrombosis, pulmonary embolism, and chronic back pain.
