how many mains zones are the internal areas of an aircraft divided into, in terms of surface protection. three. five. four.

which of the following is not a group of protective treatment mentioned?. heat treatments. special coating. paint coating.

what is the primary purpose of pretreatment of materials. to increase corrosion resistant properties and provide a good surface for paint adhesion. to make the material shiny. to increase weight.

what is the primary cause of corrosion in the general atmosphere. moisture and oxygen. carbon dioxide. lack of oxygen.

which of the following is not a step necessary for satisfactory control of corrosion?. applying heat. regular maintenance. initial identification of corrosion.

the fastener contact are of the tool must be rough and textured. false. true.

a clear indication of a loose fastener is when the head of a fastener is rolled upwards at its periphery. true. false.

if a fastener is suspected to be loose, it should be ignored until the next maintenance cycle. false. true.

the use of washer under a nut/collar is only permited when used in the original construction. true. false.

its always recommended to use two washers instead of one under the nut/collar. false. true.

the hand hammering method is the most recommended method for installing rivets in the aircraft structure. false. true.

what is the primary concern when drilling titanium due to its nature?. its hardness. its flexibility. its lightness.

what should be checked regarding the drilling equipment. wear of bearings and spindle concentricity. the brand of drill. the weight of the drill.

which of the following is not an indication of drilling problems. drill making a humming sound. drill turned blue. outer corners of drill breaking off.

which of the following is not a method used for the installation of rivets. electric drilling. hand hammering. pneumatic hammering.

what is the recommended hole pitch value for a non pressure tight joint in aluminum alloy assemblies. 4 to 6D. 5 to 7D. 3 to 4D.

for aluminum rivets installed in aluminum alloy assemblies with a thickness of 1.2 mm or thicker, what is the recommended edge distance value in terms of D. minimum 2.0 x D. minimum 1.4 xD. minimum 2.5 x D.

what is the primary benefit of the cold expansion process. it increases the fatigue life of metal structures. it increases the temperature resistance of metal structure. it increases the weight of metal structures.

by how much does the hole diameter increase as a result of the expansion process. three to five percent. two to four percent. one of two percent.

which of the following is not a step in the cold expansion of holes in aluminum alloy structure. painting the cold expanded hole. drilling a start hole. reaming the start hole.

if the maximum oversize of a hole following cold expansion is exceeded, what should be done. contact AIRBUS. re-drill the hole. ignore the discrepancy.

why is the recommended to use a lubricant when drilling aluminum alloys. to help remove swarf and reduce heat build-up. to make the hole bigger. to make the drill shiny.

after rivets are installed, why is inspection necessary. to ensure the joint is tight and rivets are correctly formed. to check the color of the rivets. to ensure the rivets are shiny.

which of the following can indicate a loose fastener. a black or dark grey stain adjacent to the fastener head. a red mark on the fastener. a shiny spot around the fastener.

what is the primary purpose of using a countersunk fastener. to give a smooth surface. to provide a decorative finish. to strengthen the material.

which of the following is not a type of tool used to produce the countersunk recess. a countersink tool with a built-in hammer. a countersink bit with an integral pilot pin. a countersink bit with a replaceable pilot pin.
