THE PASSENGER FURTHER STATED THAT HE OBSERVED A X-WIND PRIOR TO TOUCHDOWN. APRX 3 TO 5 SECONDS AFTER TOUCHDOWN THE AIRPLANE ROLLED TO THE RT & THE RT WING TIP STRUCK THE WATER, VEERING THE ACFT TO THE RT & NOSING OVER IN 8 TO 10 FT OF WATER. THE PASSENGER STATED THAT AS THIS WAS OCCURRING, THE PIC, SHOUTED 'CROSSWIND' VERY SURPRISED. AN AUTOPSY SHOWED THE PLT DIED FROM DROWNING.
