Lightning protection plating on military airplane carbon-composite parts is a process that requires careful handling of the final product, especially during maintenance of fuel, hydraulic, and electrical systems installations. This paper and the accompanying ten-minute videotype focus on the primary reasons for having to take special precautions with lightning-protection plating (especially low plating adhesion - between 1 and 2 pounds per inch-width) and the engineering rework procedures that have been developed to return damaged plating to the original configuration specified in the engineering drawing. Some of the important features of lightning-protection plating that have contributed to the virtual elimination of plating damage cases at Boeing are: the application of nickel overplating to one-third of all plated parts; edge sealing with two-part epoxy adhesives; fillet sealing with polysulfide sealants or the installation of elastomeric protective removable equipment (PREs) to parts that have been plated in conformance with the engineering requirements.
