| Confidence Rating: |  Accident investigation report completed and information captured |
The airplane impacted terrain following a descent in a right turn through instrument meteorological conditions. The left and right seated airplane occupants were both non-instrument rated private pilots. An examination of the wreckage revealed no pre-impact anomalies which would have precluded normal airplane operations. The left seat pilot was at high risk for obstructive sleep apnea (OSA), which is strongly associated with obesity and high blood pressure requiring multiple medications. Obstructive sleep apnea, if present and untreated, results in significant impairment and increased accident risk. The actual presence or possible role of possible OSA in this accident could not be conclusively determined, though such a disorder could have adversely affected the left seat pilot’s decision-making regarding initiating or continuing flight into deteriorating visibility and/or his responses to such conditions once he encountered them. The left seat pilot did not have a current medical certificate.
Probable Cause: The non-instrument rated pilot's continued flight into instrument meteorological conditions.
