## Analysis

DUE TO THE LOCATION OF A GAS SEPARATOR, THE PLT STARTED TO TAKEOFF FROM AN OIL RIG PLATFORM WITH A LEFT CROSS- WIND AT APRX 30 KTS, GUSTING 35 TO 40 KTS. AFTER LIFTING OFF TO A HOVER, WIND GUSTS WERE ENCOUNTERED. THE PLT REPORTED THAT THE ACFT TURNED 10 TO 15 DEG LEFT & BANKED APRX 10 DEG TO THE RIGHT. HE REPORTED THAT THE GUSTS LET UP SLIGHTLY & THE ACFT STABILIZED (LEVEL) MOMENTARILY, THEN ADDITIONAL GUSTS WERE ENCOUNTERED. HE STATED THAT THE ACFT ROLLED APRX 15 DEG RIGHT WHEN HE RAN OUT OF LEFT CYCLIC. REPORTEDLY, HE LOWERED THE COLLECTIVE, BUT NOT BEFORE DYNAMIC ROLLOVER COULD BE AVOIDED.
