Question: 1 / 400

Inspection of aluminum propeller blades by dye-penetrant inspection is accomplished to detect?

fatigue failure

Dye-penetrant inspection is used to detect surface imperfections, such as cracks, in aluminum propeller blades. These imperfections can lead to fatigue failure, which is the gradual weakening of materials subjected to stresses over time. Additionally, material debond, warpage, and corrosion pits are generally visible upon visual inspection, making dye-penetrant inspection unnecessary for those types of imperfections. Therefore, A is the correct option as it highlights the purpose of this type of inspection method.
