HE KEPT THE AIRPLANE HEADED INTO THE WIND AND BEACHED THE AIRPLANE ON THE OPPOSITE SIDE OF THE BAY. THE PILOT ALSO SAID THAT SUITABLE WEATHER CONDITIONS HAD BEEN REPORTED FOR THE LANDING AREA ABOUT ONE HALF HOUR EARLIER.
THE INCIDENT WAS CAUSED BY THE PILOTS IMPROPER COMPENSATION FOR THE WINDS. FACTORS WERE THE MICROBURST, THE ROUGH WATER, AND THE PILOT'S INADEQUATE EVALUATION OF THE WEATHER CONDITIONS.
