What happened
Prior to departure, the pilot received a weather briefing indicating generally good VFR conditions along the proposed route, with the primary concern being possible turbulence and significant blowing dust. Specific forecasts warned of visibilities dropping to three or four miles by noon due to the dust. Additionally, pilot reports confirmed strong winds at 3,000 feet over Oklahoma City.
Despite these warnings, and after a former flight examiner attempted to persuade the pilot to postpone the trip due to high winds en route, the flight proceeded. Approximately 15 minutes before the accident, a ground witness near Lamar Airport observed a dust cloud north of town rising to an altitude of roughly 2,000 feet. By the time the witness arrived at the airport, visibility had plummeted to less than 100 feet with estimated winds of 60 mph. Another witness who heard the crash reported that conditions were too dusty to see anything clearly.
The investigation
Observations from the La Junta Flight Service Station, located approximately 32 miles west of the accident site, recorded surface winds gusting to 57 knots and sky coverage of zero at 0958 and 1058. These meteorological data confirm the presence of a severe dust storm consistent with witness accounts.
Findings
The pilot's decision to fly into deteriorating weather conditions characterized by blowing dust and high winds contributed to the accident. The rapid reduction in visibility to less than 100 feet made visual flight impossible, leading to the loss of control or collision with terrain.
