SACAA AME Airframes Practice Questions - SACAA Aircraft Maintenance Engineer Airframes General (CAT A B) Theoretical Knowledge Examination Exam - SACAA AME Airframes Practice Questions - SACAA Aircraft Maintenance Engineer Airframes General (CAT A B) Theoretical Knowledge Examination Exam

Question 1

What primary structural difference distinguishes a semimonocoque fuselage from a pure monocoque fuselage?

Semimonocoque designs rely entirely on the outer skin to carry all flight and landing loads. Semimonocoque designs utilize internal longitudinal formers, bulkheads, and stringers to reinforce the skin. Pure monocoque fuselages use heavy internal truss frameworks made of welded steel tubing. Semimonocoque fuselages do not require bulkheads or frames for shape maintenance.

Correct Answer:

Semimonocoque designs utilize internal longitudinal formers, bulkheads, and stringers to reinforce the skin.

Question 2

Aluminum alloy 2024-T3 is widely used in airframe skins. What do the primary digit '2' and temper designation 'T3' indicate?

Major alloying element zinc; solution heat-treated and naturally aged. Major alloying element copper; strain-hardened and stabilized. Major alloying element copper; solution heat-treated, cold worked, and naturally aged. Major alloying element magnesium; solution heat-treated and artificially aged.

Correct Answer:

Major alloying element copper; solution heat-treated, cold worked, and naturally aged.

Question 3

Why is high-strength 7075-T6 aluminum alloy frequently clad with pure aluminum (Alclad 7075) when used for external fuselage skins?

To increase the overall tensile strength and fatigue limit of the sheet material. To provide cathodic galvanic corrosion protection over the core alloy susceptible to intergranular corrosion. To improve thermal conductivity during high-speed atmospheric friction. To allow easier spot-welding without removing surface oxide layers.

Correct Answer:

To provide cathodic galvanic corrosion protection over the core alloy susceptible to intergranular corrosion.

Question 4

When installing metal fasteners through carbon fiber reinforced polymer (CFRP) composite structures, which metal fastener material must be avoided due to galvanic corrosion potential?

Titanium alloy (Ti-6Al-4V) Passivated 300-series Stainless Steel Bare or cadmium-plated Aluminum alloy Inconel 718 nickel-chromium alloy

Correct Answer:

Bare or cadmium-plated Aluminum alloy

Question 5

During a potted core repair on a damaged sandwich honeycomb panel, what is the primary structural requirement regarding core removal?

Remove all damaged core material down to the opposite skin while maintaining a 1:1 bevel ratio on the face sheet. Undercut sound core material by 1.5 times the cell diameter around the perimeter of the damage. Remove damaged core back to sound material, leaving clean vertical edges, and undercut the face sheet to create a mechanical key. Remove only the outer face sheet and inject low-density resin into crushed core cells without removing them.

Correct Answer:

Remove damaged core back to sound material, leaving clean vertical edges, and undercut the face sheet to create a mechanical key.
