Aircraft Accident/Incident Report

Georgia Pass, Colorado 80424
Friday, August 15, 2008 9:15 MDT

NTSB Narrative Summary Released at Completion of Accident

The instrument-rated pilot was traveling cross-country with three passengers after a family vacation. The airplane was instrument-flight-rules equipped and the pilot was familiar with the airplane. There was no evidence the pilot obtained a weather briefing prior to departure and he did not file a flight plan. An analysis conducted by an NTSB meteorology specialist determined that, at the time of departure, weather was marginal visual meteorological conditions with an overcast layer above and scattered clouds at and below the flown flight level. Weather near the accident site deteriorated rapidly after departure and the pilot likely encountered a level 2 thunderstorm, lost control of the airplane and impacted terrain, destroying the airplane. Postaccident inspection of the airplane did not disclose evidence of any preimpact anomaly of the engine or airplane systems.

NTSB Probable Cause Narrative

The pilot's failure to maintain aircraft control after inadvertantly encountering instrument meteorological conditions. Contributing to the accident were the pilot's failure to obtain a weather brief and the severe weather conditions.
