Many hangers shelters and shilos used for storage of militaryweaponssystems are several decades old and started to show signs of aging corrosionassisted damage of support structuressuch assteel pipe stays beams joints flashings etc. in addition to roof. In particular this paper will address theissues andsolutions related with aging of a hangerwhich has corroded to a pointthat one has to address the sustainability of the structure as a major issue from atmospheric corrosion of roof and the cantilever support pipe staysunder load and stress. Inold infrastructures there is a lack of redundancy in design of thesupport frames such ascantilever portion of the hanger roof therefore thereis a concern that if one pipe-stay fails due to cross sectional metal loss fromcrevice/pittingcorrosion the adjacent stays would become potentially overloaded and cause the roof to fall.

Key words: aircraft hangar, atmospheric corrosion, roof and pipe-stay corrosion, aging, structural repairs.
