Title: Explain where on the aircraft each of the five common types of aircraft corrosion occurs.
Course: Aviation Maintenance Technology II (20114-II) > Section: Exploring the Effects of Cleaning and Corrosion

Explanation should include

- oxidation—on the surface/skin of an aircraft
- oxygen concentration cell corrosion—under lap joints, beneath marking tape, under ferrules on aluminum fluid lines
- metallic ion concentration corrosion—under lap joints
- stress corrosion—on bell cranks with pressed-in bushings, landing gear shock struts with pipe-thread grease fittings, clevis pin joints, shrink fits, overstressed tubing with B-nuts
- fretting corrosion—around skin surface rivets.

Process/Skill Questions:

- Why is it important to recognize where each type of corrosion occurs on the aircraft?
- How can a mechanic reduce stress corrosion on an aircraft?
