Accident Sequence
The accident occurred during a test flight following minor engine maintenance performed by the pilot, who was also a mechanic. The engine cowling was not installed prior to the flight. According to witnesses, the aircraft's wheels touched the water of a nearby pond, after which the pilot executed a sharp pull-up into a maneuver described as his customary 'loop' before landing. The aircraft did not complete the loop and impacted the ground at a 75-degree nose-down attitude.
Post-Accident Findings
Toxicological analysis conducted by the Harris Medical Lab in Fort Worth, Texas, revealed the pilot's blood alcohol level to be 176 mg/dL. Additionally, examination of the pilot's body revealed evidence of severe coronary artery disease; however, its relevance to the accident could not be established.
