Accident Overview
A private pilot experienced an incapacitating medical event during the initial segment of takeoff, which led to a loss of aircraft control. The airplane subsequently impacted the waters of the Mississippi River and came to rest submerged in approximately 12 feet of water.
Pilot and Aircraft
The pilot, the sole occupant, held a private pilot certificate. The aircraft sustained substantial damage and was destroyed in the accident. Examination of the wreckage, including the engine, revealed no evidence of any preexisting engine or airframe malfunctions.
Medical and Autopsy Findings
An autopsy was conducted, and the cause of death was determined to be "drowning in association with arteriosclerotic heart disease." The pilot's incapacitation was consistent with a medical event that compromised his ability to control the aircraft.
Impact and Submersion
The aircraft struck the Mississippi River and sank in shallow water, approximately 12 feet deep. The accident site was within the river channel. No other injuries or damage to property were reported.
