What tests are used to demonstrate that a mechanic applicant has the proper knowledge?

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

Answer: (D)

Knowledge is demonstrated through written knowledge tests. These exams measure what you know across the required subjects, such as airframe and powerplant fundamentals, regulations, and maintenance practices. Passing the written tests shows the theoretical understanding needed before moving on to the hands-on portions, where the applicant must apply that knowledge during oral and practical assessments. Flight tests are for pilots, and simulator tests aren’t part of the standard mechanic certification process, so the written knowledge tests are the ones used to demonstrate proper knowledge.
