This report summarizes the Westland Helicopters, Ltd., approach to corrosion control in helicopters 1 All drawings are vetted before issue to ensure that obvious corrosion sites, sharp edges, water traps are designed out and to obtain the most economical means of protecting components. Some designs deposited material is significant compared with labor cost and so believe that it is more economic to partially electroplate rather than electroplate all over the part. 2 Wherever possible apply a coat of paint before assembly. 3 Measures are taken to prevent ingress of water to joints and structures by the use of caulking materials however, great care is taken to ensure structures are adequately drained.
