Test on Non-Destructive Inspection Methods

Question 1: Is it necessary to use the magnetic particle method to inspect a nonferrous metal part?

A. Ano

B. Ne

Explanation: The magnetic particle inspection method requires the metal part to be of magnetic material, such as iron or steel, not nonferrous.

Question 2: Outside, inside, depth, and thread micrometers are recognized types of micrometer calipers.

A. Ano

B. Ne

Explanation: The different types of micrometer calipers include outside, inside, depth, and thread micrometers.

Question 3: Which sequence of steps is part of a dye penetrant inspection procedure?

A. Applying the developer before drying the part after penetrant removal.

B. Thoroughly cleaning the metal surface, applying the penetrant, then drying the part.

C. Removing the penetrant from the surface, drying the part, and then applying the developer.

D. Applying the penetrant, inspecting the results, and then cleaning the metal surface.

Explanation: The study materials state the procedure includes: 'Thoroughly clean the metal surface, dry completely, and apply the penetrant. Remove the penetrant from the surface, dry the part, and apply the developer. Inspect and interpret the results.' Option 2 correctly describes 'Removing the penetrant from the surface, drying the part, and applying the developer' as sequential steps in the process.

Question 4: Where would an aircraft operator find the approved inspection programs for an aircraft?

A. The aircraft manufacturer's maintenance manual.

B. The aircraft's daily flight log.

C. The Instruction for Continued Airworthiness (ICA).

D. The Federal Aviation Administration (FAA) website.

Explanation: Approved inspection programs for an aircraft are found in the aircraft manufacturer's maintenance manual and the Instruction for Continued Airworthiness (ICA).

Question 5: Grease or dirt in a fault keeps penetrant from seeping into the fault.

A. Ano

B. Ne

Explanation: Any grease or dirt in a fault will keep the penetrant from seeping into the fault.
