Aircraft Accident/Incident Report

Mack, Colorado 81525
Monday, May 8, 2000 12:50 MDT

NTSB Narrative Summary Released at Completion of Accident

The instrument rated pilot received 3 weather briefings and waited 3 hours for weather to improve before departing on a VFR flight. According to witnesses, the mountain tops in the vicinity of the pilot's route of flight were obscured by clouds. The pilot told the witnesses that he was concerned with the freezing level and therefore wanted to stay VFR. The pilot told the FSS weather briefer that he was trying to stay out of icing conditions and the lower he flew the better. The pilot filed a flight plan that had an intended route of flight along a victor airway at VFR altitudes. Radar data depicted the accident airplane climbing to a maximum altitude of 8,700 feet msl and heading northwest on course before radar contact was lost. The radar altitude data was overlaid on topographical data and revealed the terrain rising to meet the airplane's last radar altitude return. The airplane impacted mountainous terrain at 8,736 feet msl. Weather reports along the route of flight depict cloud bases initiating approximately 7,300 feet msl. Examination of the wreckage revealed no anomalies that would have prevented normal operation of the aircraft.

NTSB Probable Cause Narrative

The pilot's continued VFR flight into instrument meteorological conditions. Factors were the mountain obscuration and the rising terrain.
