(AGARD-AG-278, 1985) gives the following guidance for high risk areas for corrosion. These are not the only areas at risk – all regions of the aircraft may corrode. Special care should be taken in the following areas to either avoid problematic material combinations or to provide additional mitigation to avoid corrosion.
