Module 7 — Maintenance Practices

7.18(a) — Types of Defects and Visual Inspection

Practice questions test what you know. This note teaches what you don’t.

Question banks train recall. The questions that decide a pass are the borderline ones, where two answers look right — and those are won by understanding. That is what this note is written for.

Locked Inside this note

This section covers the types of defects found in aircraft structures and components, visual inspection techniques, and corrosion management — all at Level 3 for B1, B2, B2L, and B3 categories.
