Accident Overview
An aircraft crashed after witnesses observed it flying low along the approach course through clouds. The landing light was illuminated and the engine was operating normally. Multiple tree contacts were heard before the aircraft struck the ground, followed by explosions.
Witness Observations
Witnesses reported the aircraft on a low approach path with the landing light on. The engine sounded normal. They heard the aircraft contact trees several times before it crashed and exploded.
Aircraft Examination
A post-crash examination of the aircraft structure, flight controls, engine, and vacuum pump revealed no evidence of precrash failure or malfunction.
Medical Findings
The medical examiner reported that the pilot had severely restrictive coronary artery disease. There was no evidence of fire inhalation or premortem fractures of the skull, spine, ribs, or limbs. The examiner stated that, in view of the coronary disease, it appears likely the pilot suffered a heart seizure and lost awareness.
Medications and Medical Certification
Postmortem toxicology tests indicated the pilot was taking metoprolol and naproxen, prescribed for hypertension. The pilot had not reported the hypertension or medication use to the FAA. He had undergone an FAA medical examination two days before the accident.
