Aircraft damage: Substantial
Location:Las Vegas, NM -   United States of America
Departure airport:Dalhart, TX (DHT)
Destination airport:Santa Fe, NM (SAF)
Investigating agency: NTSB
The private pilot departed on a cross-country flight in day visual meteorological conditions. When he did not arrive at his destination as planned, a search was initiated, and the airplane was subsequently located in wooded, mountainous terrain near a private airport about 73 miles short of the destination. The orientation of the wreckage was consistent with the airplane impacting terrain following an aerodynamic stall. Examination of the airplane and engine did not reveal any anomalies that would have precluded normal operation, and there was evidence of fuel at the accident site.

The pilot was not in contact with air traffic control during the flight. Radar information showed the airplane maneuvering near the airport before radar contact was lost; the pilot may have been attempting to divert to the airport when the accident occurred. An autopsy of the pilot revealed severe coronary artery disease with 90% stenosis of the left coronary artery as well as evidence of scarring from a previous heart attack. Each of these conditions placed the pilot at significantly increased risk for the sudden development of symptoms from an acute cardiac event, which may have led him to divert. It is likely that, while maneuvering for landing, the pilot was either impaired or incapacitated by the symptoms of an acute cardiac event, which subsequently resulted in a loss of control.

Probable Cause: The pilot's impairment or incapacitation by symptoms of an acute cardiac event, which resulted in a loss of control.
