A FUEL SAMPLE WAS FOUND TO BE WITHIN SPECIFIED PARAMETERS. AC 61-13B STATES 'HOVERING TURNS SHOULD BE AVOIDED IN WINDS STRONG ENOUGH TO PRECLUDE SUFFICIENT AFT CYCLIC CONTROL TO MAINTAIN THE HELICOPTER ON SELECTED SURFACE REFERENCE POINT WHEN HEADED DOWNWIND. CHECK THE HELICOPTER FLIGHT MANUAL FOR MANUFACTURER'S RECOMMENDATIONS FOR THIS LIMITATION.' 'HOVERING POWER REQUIRES A LARGE AMOUNT OF LEFT PEDAL TO MAINTAIN HEADING. SUFFICIENT LEFT PEDAL IN EXCESS OF THIS AMOUNT MUST BE AVAILABLE TO PREVENT AN UNCONTROLLED TURN TO THE RIGHT ONCE THE TURN HAS BEGUN.'
