What happened
Following its departure for a cross-country flight, the aircraft climbed to a cruise altitude of 9,700 feet MSL and proceeded on a magnetic course of 050 degrees. Approximately 11 minutes into the flight, the aircraft began a steady descent at a rate of 1,000 feet per minute. This descent continued until the aircraft struck terrain at an elevation of 4,734 feet. At the moment of impact, the aircraft remained on its intended northeasterly path. Physical evidence at the crash site indicated the aircraft was in a slight nose-down pitch with its wings level.
Findings
An inspection of the wreckage and engine revealed no mechanical failures or anomalies. Weather conditions during the flight were reported as clear with light winds. A post-impact fire resulted in the total destruction of all cockpit instruments, making the recovery of flight data impossible.
Medical examinations of the pilot revealed a history of moderate heart disease, stress, and insomnia. Toxicology reports identified the presence of chlorpheniramine, a sedating over-the-counter medication, in the pilot's system. While these medical factors were documented, investigators could not definitively link the pilot's health or medication use to the descent. Ultimately, the specific reason for the aircraft's descent and subsequent impact could not be determined.
