Which type of testing is used to demonstrate the mechanic applicant's knowledge?

• A. The oral and practical tests.
• B. The flight tests.
• C. The written knowledge tests.
• D. The simulator tests.

Answer: (C)

Written knowledge tests are used to demonstrate the applicant’s knowledge because they specifically measure understanding of the theory behind maintenance, regulations, and system fundamentals. These tests assess what the candidate knows on paper—topics like general aviation knowledge, airframe and powerplant theory, and applicable regulations—before any hands-on work is evaluated. The oral and practical exam, by contrast, is about applying that knowledge in real tasks and demonstrating technical skills. Flight tests are for pilots testing flying ability, not the maintenance knowledge base. Simulator tests aren’t the standard method for proving foundational knowledge in the mechanic certification process.
