Abstract : This study was performed to assess the risk associated with accidents involving aircraft with carbon fiber composite structural components. Concern was engendered as the result of evidence that individual fiber segments could cause electrical and electronic equipment to fail under certain operating conditions. The method used to compute the risk is essentially a Monte Carlo simulation model. The principal elements in the scenario that is simulated are: aircraft accident with fire; release of carbon fiber material; entrainment of carbon fibers in a smoke plume; transport of fibers downwind; transfer of some fibers into the interior of buildings; failures of electrical and electronic equipment; economic impact of failures. Risk profiles were prepared for individual airports and the Nation. Parallel efforts investigated the vulnerability of electrical transmission equipment to carbon fiber incursion and aircraft accident total costs.
