Dynamic rollover occurs when a helicopter pivots around a fixed point on the landing gear with a rolling moment that exceeds the rotor system’s corrective authority. On uneven or soft terrain, mud, debris, or rocks under one skid can create a pivot point. Removing debris and confirming both skids are on firm, level ground with minimal slope angle significantly lowers rollover risk. Latched doors and lighting are important but do not address the primary rollover mechanism. Securing patient straps is essential for patient safety but has no effect on airframe stability. The crew should also verify minimal lateral cyclic input, avoid abrupt collective increases, and follow the pilot’s commands precisely during liftoff. A thorough LZ reassessment for slope, obstacles, and wind, coupled with skid inspection, is the most direct mitigation against dynamic rollover in the pre-liftoff phase.
