What happened
During an instrument flight rules (IFR) operation within instrument meteorological conditions (IMC), the pilot was conducting a localizer back course 27 approach. Following this procedure, a missed approach was performed. While attempting a subsequent ILS approach for runway 09L, the aircraft disappeared from radar and radio communications.
Search efforts located the wreckage approximately one-half mile east of the Saige locator outer marker, positioned along the inbound approach path. The impact forces and a subsequent fire resulted in the total destruction of the aircraft. There was one fatality involving the pilot, who was the only person on board at the time of the accident.
Findings
Investigations into the medical history and autopsy of the pilot indicated that he suffered from physical impairment related to a cardiovascular condition, which led to his incapacitation during the flight. This loss of control caused the aircraft to collide with the terrain while transitioning from the final approach fix toward the runway threshold.
