What was found
(CAN) ON TAKEOFF RUN, AT APPROXIMATELY 2 FT OFF THE WATER, A/C SETTLED BACK DOWN DUE TO UNSTABLE AIR. A NOISE WAS HEARD AND THE A/C BECAME VERY UNSTABLE. ABORTED TAKEOFF. AS THE A/C SLOWED DOWN & THE LIFT DISSIPATED, THE LT WING SUDDENLY DIPPED DOWN AND CAME IN CONTACT WITH THE WATER CAUSING THE A/C TO VEIR LT ABRUPTLY, DISPLACING A CONSIDERABLE AMOUNT OF WATER, BUT MANAGE TO KEEP THE A/C FROM INVERTING. CAUSED ALL THE FITTING ON THE END OF THE FLOAT STRUTS TO FAIL. THE FINAL RESTING POSITION OF THE A/C WAS ENGINE POINTING UP, TAIL AND LT WING TIP PARTIALLY SUBMERGE. THE A/C WAS TOWED AND BEACHED. UPON INSPECTION, IT WAS FOUND THAT BOTH CROSS WIRES WERE BROKEN ALLOWING THE WING TO GO DOWN.
