Introduction
On April 30, 1994, the wreckage of an aircraft was found approximately 20 miles northeast of Baker. The pilot and one passenger had attended a weekend-long gathering where some attendees reported vomiting and diarrhea, possibly due to food poisoning. However, there were no reports that the pilot or passenger displayed any symptoms prior to departure.
Flight Details
Radar tracked an unidentified VFR transponder target at 8,500 feet mean sea level until it disappeared near the crash site. No air traffic control facility reported any contact with the pilot after departure.
Wreckage Examination
Examination of the wreckage revealed that the airplane had impacted in a high-speed 75-degree descent. The airplane was equipped with a throw-over yoke, and neither of the passengers were rated pilots. No evidence was found to indicate a mechanical malfunction of the aircraft or its components.
Pilot Background
The pilot's family reported a family history of early heart disease, and the pilot had an elevated level of cholesterol.
Weather Conditions
An AIRMET was in effect at the time of the accident, advising that occasional moderate turbulence could be expected below 20,000 feet.
Conclusion
The investigation did not determine a probable cause. The aircraft impacted terrain at a high speed in a steep descent, with no mechanical issues identified.
