It is believed they were caused by large flapwise deflections during a wind storm on December 4, 1978. The deflections caused the skin to buckle, which initiated rapidly growing fatigue cracks. Propagation continued to the leading edge, moving radially inward and outward along the leading edge radius. Communication between Rockwell and Millville resulted in a modified blade design which incorporates several corrective techniques N2 - Introduction - Machine overview - Loading conditions - Failure analysis - Discussion - Alanysis conclusions - Manufacturer modifications - Comments - References UR - https://www.osti.gov/servlets/purl/5596440/ ER -
