Corrosion maintenance on both commercial and military aircraft is based on finding and fixing the damage prior to its becoming a structural or safety concern. There has been little emphasis on the development of engineering tools needed for the management of this corrosion and the associated maintenance and repair actions. The benefits and longevity of corrosion prevention and control measures have not been quantified so optimization of these actions has not been possible. The costs of corrosion maintenance have risen drastically. A unique method to measure corrosion growth was required to give usable numbers in a reasonable length of time with a manageable physical configuration. Such a unique corrosion exposure test rack was developed by Dr. William Abbott of Battelle Laboratories in Columbus OH. The test setup involves a small exposure rack with coupons of bare copper, silver, two aluminum alloys, and mild steel. A single card containing these coupons can be removed and analyzed while leaving additional cards for continued environmental exposure. Typically, a card is pulled every three months, with a total exposure of one year at each location. Various configurations of these racks have been exposed at over 100 aircraft locations throughout the world. A program of an aircraft exposure was begun to correlate the actual aircraft exposure with rates determined from ground based racks located near the aircraft parking ramps. Corrosion damage impacts maintenance costs, safety and structural integrity. Engineering tools are required to allow a shift from simply finding and fixing the corrosion to predicting corrosion growth and managing it through new control technologies and optimized maintenance actions.
