Aircraft Accident/Incident Report

Sanderson, Florida 32087
Wednesday, July 8, 2009 9:05 EDT

NTSB Narrative Summary Released at Completion of Accident

The non-instrument-rated pilot departed on a visual flight rules flight without obtaining a weather briefing. Review of Doppler radar obtained from the National Weather Service depicted two bands of thunderstorms over northern Florida, the first running east-to-west and the other running northeast-to-southwest along central and western Florida. Recorded radar data showed the accident airplane's flight track approaching the band of thunderstorms, turning northeast and parallel to the weather, and then passing between the two weather areas. The flight track then turns back northwestward and penetrates the area of thunderstorms. A witness stated that the clouds in the vicinity of the crash site were overcast about 200 feet with light rain and distant thunder. Examination of the airplane revealed the vertical stabilizer and rudders separated and were not located. Examination of a tail cone section revealed fracture surfaces on the front and rear spar, and the rear doubler assembly exhibited slant-fracture features consistent with ductile overload due to exceeding the design limits. There was no evidence of preexisting damage due to fatigue or corrosion.

NTSB Probable Cause Narrative

The pilot's continued visual flight into instrument meteorological conditions with convective activity and thunderstorms. Contributing to the accident was his failure to get an adequate weather briefing.
