| __ is used when a procedure is mandatory. | Shall |
| __ is used when a procedure is recommended but not mandatory. | Should |
| __ indicates future action but does not indicate a mandatory procedure. | Will |
| __ is used only when a procedure is optional. | May |
| __ is an operation or maintenance procedure, practice, condition, or statement, which if not strictly observed, could result in injury to or death of personnel, or long term health hazards to personnel. | Warning |
| __ is an operating or maintenance procedure, practice, condition, or statement, which if not strictly observed, could result in damage/destruction of equipment or loss of mission effectiveness. | Caution |
| __ is an operating procedure, practice, or condition which is essential to emphasize. | Note |
| __ is when a complete replacement of all pages with all changes information incorporated. | Revisions |
| __ is between revisions, routine changes may be issued in the form of corrected pages to a portion of the existing manual. | Routine Changes |
| __ is when changes may be issued as a formal RAC or an IRAC. | Rapid Action Change |
| __ is the chemical or electrochemical deterioration of a material. | Corrosion |
| Corrosion can cause complete failure of equipment that is active on a __ basis. | 24 hour |
| __ is a natural continuing process of materials returning to their normal state. | Corrosion |
| __ will affect equipment life cycles, downtime, and overall system reliability. | Corrosion Prevention |
| __ is the electrochemical deterioration of a material or its properties due to its chemical reaction with the surrounding environment. | Corrosion |
| The most common type of corrosion is __. | Electrochemical Corrosion |
| __ is the smallest unit of an element, made up of a positively charged nucleus surrounded by a system of negatively charged electrons. | Atom |
| __ is a negatively charged subatomic particle. | Electron |
| __ is an atom or group of atoms or molecules which has acquired a net electric charge by gaining or losing electrons. | Ion |
| __ is a liquid solution containing ions. | Electrolyte |
| How many conditions must exist before a metal will corrode. | Four |
| __ is a corroding metal. | Anode |
| __ is a dissimilar conductive material. | Cathode |
| A electrolyte must connect to an anode and a cathode so __ can carry electric current between them. | Ions |
| The elimination of any one of the four conditions will __ corrosion. | Slow or Stop |
| The best time to prevent corrosion is at the __ stage. | Design |
| If the anode is smaller than the cathode, corrosion will be __. | Rapid and Severe |
| Most alloys are made up entirely of small crystalline regions called __. | Grains |
| Many alloys used in aircraft construction are sensitive to a form of corrosion known as __. | Stress Corrosion Cracking |
| __ occurs when different metals are in contact with each other and an electrolyte. | Galvanic Corrosion |
| Which corrosion is recognized by the presence of a buildup of corrosion deposits at the joint between the metals. | Galvanic Corrosion |
| __ is a form of extremely localized attack that results in holes in the metal. | Pitting Corrosion |
| Which corrosion is first noticeable as a white or gray powdery deposit, similar to dust, which blotches the surface. | Pitting |
| __ is an attack on the grain boundaries of the metal. | Intergranular Corrosion |
| __ is an advanced form of intergranular corrosion where the surface grains of a metal are lifted up by the force of expanding corrosion products occurring at the grain boundaries. | Exfoliation Corrosion |
| Which corrosion is know for lifting up or swelling? | Exfoliation Corrosion |
| __ is one of the most familiar types of Corrosion. | Crevice Corrosion |
| Which corrosion appears in any crevice where a stagnant solution has pooled. | Crevice Corrosion |
| __ is a form of crevice corrosion which occurs on metal surfaces having a thin (-4 mils) organic protective coating. | Filiform Corrosion |
| Which corrosion is recognized by its characteristic wormlike trace of corrosion products beneath the coating. | Filiform Corrosion |
| __ is the increase in the rate of attack on a metal due to the action of a corrosive fluid against the metal surface. | Erosion Corrosion |
| Which corrosion is characterized by grooves, gullies, waves, rounded holes and valleys in the metal surface. | Erosion Corrosion |
| __ is the intergranular or transgranular cracking of a metal caused by the combined effects of constant tensile stress and corrosion. | Stress Corrosion |
| __ is the cracking of metals caused by the combined effects of cyclic stress and corrosion. | Corrosion Fatigue |
| __ occurs at contact areas between materials under load subject to repeated vibrations. | Fretting Corrosion |
| Which corrosion has the appearance of galling, where chunks of metal are torn from the surface with corrosion at the torn areas or ragged pits. | Fretting Corrosion |
| What is another name for high temperature oxidation. | Hot Corrosion |
| Corrosion of __ is easily recognized by red rust. | Steel |
| __ has the tendency to grow whiskers. | Tin |
