4.4.3. Corrosion Prone Regions of the Aircraft.

Reference: Abbott, Richard. Analysis and Design of Composite and Metallic Flight Vehicle Structures 3 Edition, 2019

 (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.

Figure 4.4.3‑1: Regions of the Aircraft Susceptible to Corrosion (AGARD-AG-278, 1985)

Other regions of the aircraft also prone to corrosion:

  • Landing Gear
  • Flight control surface connections and any exposed hinge lines (doors, trim tabs, etc)
  • High lift devices mechanisms and hinges/tracks
  • Freight Doors
  • Control Cables

For military aircraft:

  • Cockpit Frames
  • Missile and gun blast areas
  • Engine Intake Areas
  • Wing Fold Areas
