NTSB Narrative Summary Released at Completion of Accident
THE PLT REPORTS THAT THE WIND WAS LIGHT DURING TAKEOFF AND WHILE CRUISING. WHEN THE PLT DESCENDED FOR LANDING HE ENCOUNTERED STRONG, GUSTY WINDS FROM ABOUT 50 TO 60 FT AGL DOWN TO THE GROUND. ACCORDING TO THE PLT, THESE STRONG, LOCALIZED WINDS ARE UNPREDICTABLE AND OCCUR ON AN INFREQUENT BASIS.
