Module 7 — Maintenance Practices

7.18(b) — General Repair Methods

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

When damage is found, the maintenance engineer must determine the appropriate repair method. Repairs must restore the structural integrity of the component to at least its original strength while maintaining the aerodynamic profile, weight distribution, and fatigue life. All repairs must be carried out using approved data — primarily the Structural Repair Manual (SRM).
