What happened
The aircraft was operating as a ferry flight originating from Lincoln, Nebraska. At the time of the incident, two pilots were on board. While traversing airspace over Colorado at an altitude of approximately 8,500 feet, the airplane struck Black Mountain. The impact site was located roughly 15 kilometers west of Guffey. Both individuals on board were killed in the collision.
Findings
Investigations determined that the crew members were asleep during the critical phase of the event. The autopilot system remained engaged at the time of the terrain impact. This state resulted in a controlled flight into terrain, leading to the fatal outcome for both occupants.
