In the past, the RAF's approach to corrosion was reactive: corrosion occurred, was identified and then rectified. Such a strategy is no longer acceptable, as corrosion rectification is costly both in terms of material and aircraft availability. More importantly, as escalating replacement costs force us to retain aircraft in service for ever longer periods, the threat posed to structural integrity by corrosion and repeated corrosion repairs can no longer be tolerated. Consequently, the RAF has had no option but to develop a policy of corrosion prevention.
