- 201.A technician is performing a visual inspection of a steel aircraft component. Which type of corrosion is characterized by a general roughening of the surface and a red, flaky deposit?Materials, Hardware and Processes
- 202.A technician is preparing to weld an aluminum alloy component. To prevent the formation of aluminum oxide, which has a much higher melting point than aluminum itself, what type of welding current is typically used for aluminum and why?Materials, Hardware and Processes
- 203.A technician is installing a new navigation light bulb rated at 28 volts and 0.5 amperes. What is the resistance of the bulb's filament when it is operating normally?Fundamentals of Electricity and Electronics
- 204.A technician is inspecting a composite structure for delamination using a non-destructive testing method. Which method utilizes high-frequency sound waves to detect flaws by analyzing reflections and transmissions through the material?Materials, Hardware and Processes
- 205.A technician is troubleshooting an aircraft electrical system and notes that the voltage measured across a specific component is 0 volts, while the current flowing through it is extremely high. Which type of circuit fault is most likely indicated by these readings?Fundamentals of Electricity and Electronics
- 206.A repair station needs to identify the type of stainless steel used in a non-magnetic component. A simple field test involves using a magnet. Which series of stainless steel is generally non-magnetic in its annealed condition and commonly used in aircraft for its corrosion resistance?Materials, Hardware and Processes
- 207.A technician is checking the state of charge of a 24-volt nickel-cadmium aircraft battery. What is the approximate open-circuit voltage per cell for a fully charged nickel-cadmium cell?Fundamentals of Electricity and Electronics
- 208.A technician is troubleshooting a transistor circuit and determines that the transistor is an NPN type. For the transistor to be properly biased in the active region for amplification, what should be the polarity of the voltage applied to the base-emitter and base-collector junctions, respectively?Fundamentals of Electricity and Electronics
- 209.A mechanic is fabricating a new control cable terminal for a flight control system using swaging. Assuming the cable has a nominal diameter of 1/8 inch, what is the maximum permissible number of broken wires in any 1-inch length for a 7x19 extra-flexible cable before it must be replaced?Materials, Hardware and Processes
- 210.A mechanic is inspecting a composite panel that has been exposed to moisture and freezing temperatures. Which type of damage is characterized by the separation of layers within the laminate, often caused by the expansion of trapped moisture during freezing?Materials, Hardware and Processes
- 211.A technician is installing a new structural bolt in a critical airframe location. The bolt is subjected to both shear and tensile loads. Which type of bolt is specifically designed to withstand high shear loads and is commonly identified by its close-tolerance shank and often a shorter grip length?Materials, Hardware and Processes
