NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot had been spraying fungicide on corn fields when the accident occurred. There were no witnesses to the accident. Examination of the accident site indicated that the airplane had impacted the ground at a high angle and that there was a post-impact fire. Engine examination bore evidence consistent with power being developed at the time of impact. No preimpact malfunctions or failures were found that would have precluded normal operation. Autopsy of the pilot revealed non-ischemic dilated cardiomyopathy, but the severity could not be determined. Since the pilot did not have any known personal physician and there was no evidence that he had ever sought treatment for this condition, it is likely that it had gone undiagnosed. Patients diagnosed with non-ischemic dilated cardiomyopathy who also have significant left ventricular dysfunction are at increased risk for sudden cardiac death. The pilot had a significant risk factor for cardiac arrhythmias, but the fact that he had significant bleeding associated with the injuries due to the accident suggests that he did not experience sudden cardiac death before impact. The possibility of preimpact impairment or incapacitation of the pilot could not be definitively established.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The loss of airplane control for reasons that could not be determined because postaccident examination of the engine did not reveal any anomalies that would have precluded normal operation and evidence was insufficient to definitively establish whether the pilot was impaired or incapacitated.
