AMT223 QB 3 and 4

(8041) A well-designed rivet joint will subject the rivets to

• a. compressive loads.

• b. shear loads.

• c. tension loads

(8103) Shallow scratches in sheet metal may be repaired by

• a. burnishing.

• b. buffing.

• c. stop drilling.

(8106) A single-lap sheet splice is to be used to repair a section of damaged aluminum skin. If a double row of 1/8-inch rivets is used, the minimum allowable overlap will be

• a. 1/2 inch.

• b. 3/4 inch.

• c. 13/16 inch.

(8114) When repairing a small hole on a metal stressed skin, the major consideration in the design of the patch should be

• a. the shear strength of the riveted joint.

• b. to use rivet spacing similar to a seam in the skin.

• c. that the bond between the patch and the skin is sufficient to prevent dissimilar metal corrosion.

(8116) Repairs or splices involving stringers on the lower surface of stressed skin metal wings are usually

• a. not permitted.

• b. permitted only if the damage does not exceed 6 inches in any direction.

• c. permitted but are normally more critical in reference to strength in tension than similar repairs to the upper surface.

(8117) When straightening members made of 2024-T4, you should

• a. straighten cold and reinforce.

• b. straighten cold and anneal to remove stress.

• c. apply heat to the inside of the bend.

(8121) A factor which determines the minimum space between rivets is the

• a. length of the rivets being used.

• b. diameter of the rivets being used.

• c. thickness of the material being riveted.

(8126) Rivet gauge, or transverse pitch is the distance between the

• a. centers of rivets in adjacent rows.

• b. centers of adjacent rivets in the same row.

• c. heads of rivets in the same row.

(8127) Rivet pitch is the distance between the

• a. centers of rivets in adjacent rows.

• b. centers of adjacent rivets in the same row.

• c. heads of rivets in the same row.

(8129) What is indicated by a black 'smoky' residue streaming back from some of the rivets on an aircraft?

• a. Filiform corrosion is occurring between the rivets and the skin.

• b. Intergranular corrosion is occurring between the rivets and the skin.

• c. Fretting corrosion is occurring between the rivets and the skin.
