Collision
The aircraft collided with gently rolling terrain that was covered with snow. The terrain impact led to damage of the aircraft. The accident scene was examined by investigators.
Medication and Medical History
During the wreckage examination, a small empty plastic medicine bottle bearing the label "Nadalol" was located. Nadalol is a beta-blocker medication that is used to manage symptoms including dizziness, fatigue, and mental depression.
Information provided by the pilot's insurance agent indicated that the pilot had a history of Reiter's syndrome. Reiter's syndrome is characterized by a triad of symptoms: monogococcal urethritis, conjunctivitis, and arthritis. The investigation was unable to determine whether the pilot was experiencing symptoms of Reiter's syndrome at the time of the accident. Additionally, it could not be established how recently the pilot had taken Nadalol.
