Question 1
What reduces the air pressure between the engine and reservoir in a hydraulic system pressurized with turbine engine compressor bleed air?
Correct Answer:
Air pressure regulator
Explanation:
The other options are incorrect because B is a part of the hydraulic system but not specifically what reduces air pressure. C is incorrect because it adds air to the system rather than reducing air pressure. D is incorrect because it is designed to relieve abnormally high pressure, not reduce air pressure.
Question 2
What procedure should be followed if the pressure of a fire extinguisher container is not within the minimum and maximum limits?
Correct Answer:
Replace the extinguisher container.
Explanation:
If the pressure of a fire extinguisher container is not within the minimum and maximum limits, the correct procedure to follow is to replace the extinguisher container. This is necessary because the pressure limits are crucial for the correct functioning of the fire extinguisher. If the pressure is outside the specified range, it can affect the performance of the extinguisher in case of an emergency. Therefore, replacing the container is the appropriate action to take in this situation. Option A is incorrect because simply refilling the extinguisher container will not address the underlying issue of the pressure being outside the acceptable limits. Option B is incorrect as performing a pressure test may not solve the problem with the existing container and its pressure. If the pressure is already outside the limits, conducting a test may confirm the issue but will not fix it. Option D is also incorrect as checking for leaks and repairing them will not necessarily resolve the problem of the pressure being outside the acceptable range. In such a situation, it is best to replace the container to ensure the fire extinguisher operates effectively when needed.
Question 3
What is one of the main advantages of Hi-Lok type fasteners?
Correct Answer:
They can be installed with ordinary hand tools
Explanation:
Hi-Lok type fasteners have the main advantage of being able to be installed with ordinary hand tools. This is a significant benefit as it simplifies and expedites the installation process compared to fasteners that require special tools. Hi-Lok fasteners are commonly used in aviation maintenance due to their ease of installation and reliability.
Question 4
What is the operating principle of the sensing device used in an autopilot system?
Correct Answer:
The relative motion between a gyro and its supporting system
Explanation:
The operating principle of the sensing device used in an autopilot system is the relative motion between a gyro and its supporting system. This is because gyroscopes work based on the principle of conservation of angular momentum, where the rotor maintains its orientation regardless of the movement of the base. Additionally, gyroscopes provide accurate measurements of pitch, roll, and yaw, making it an ideal sensing device for an autopilot system. The other options are not correct because A) Electrical resistance change is not a standard operating principle for autopilot systems. This option may be applicable in other sensing devices, but not in this scenario. B) Magnetic field variation is not used in most autopilot systems as it may be influenced by external factors, making it less reliable. D) Pressure differential may be used in altitude or airspeed sensors but is not the primary operating principle in autopilot systems.
Question 5
How is cold air supplied in some turbine aircraft where hot compressor bleed air operates the conditioned air system?
Correct Answer:
By the air cycle machine turbine
Explanation:
In some turbine aircraft, where hot compressor bleed air operates the conditioned air system, cold air is supplied by the air cycle machine turbine. The air cycle machine is a type of air conditioning system commonly used in aircraft. It operates by utilizing the hot compressor bleed air to remove heat from the cabin air and then supply cold air back into the cabin. Vent windows, liquid cooling systems, and external air sources are not the methods used to supply cold air in turbine aircraft with this type of air conditioning system.

What the Course Entails and Exam Details

The path to obtaining an FAA AMT Airframe rating involves comprehensive training covering a wide array of topics crucial for aircraft maintenance. The course curriculum typically encompasses both theoretical knowledge and practical skills development. Students dive deep into subjects such as aircraft structures (wood, fabric, and metal), welding, assembly and rigging, airframe systems (hydraulic, pneumatic, electrical, communication, and navigation), landing gear, fuel systems, and cabin atmosphere control. This thorough training ensures that candidates are well-versed in the intricate components and systems that keep aircraft flying safely.


What to Expect in the Final Exam

The FAA AMT Airframe certification process consists of multiple exams aimed at evaluating a candidate's competence. While specific details can vary, candidates generally encounter a written multiple-choice exam, an oral exam, and a practical exam. The written portion focuses on demonstrating theoretical knowledge, covering the diverse topics mentioned earlier. A passing score of 70% or higher is typically required. The oral and practical exams, conducted by a Designated Mechanic Examiner (DME), assess a candidate's ability to apply their knowledge in real-world scenarios and perform hands-on maintenance tasks. Candidates should prepare for a rigorous evaluation of their skills and understanding of airframe systems.


How to Study and Exam Centers

Preparation for the FAA AMT Airframe exam demands dedication and a structured study approach. Aspiring technicians can utilize various resources, including FAA-approved handbooks, textbooks, online study guides, and practice exams. Engaging in hands-on training at an FAA-certificated Part 147 aviation maintenance technician school is highly recommended to build practical skills. When it comes to taking the written exam, candidates can schedule their test at an authorized testing center. These centers are often located within aviation schools, airports, or specific testing facilities. Detailed information about exam registration, locations, and requirements can be found on the FAA's official website or by contacting local testing coordinators.


Job Opportunities from the Course

Upon earning the FAA AMT Airframe certification, a range of exciting career opportunities opens up within the aviation maintenance sector. Graduates can pursue roles such as:

  • Aircraft Mechanic

  • Airframe Technician

  • Aviation Maintenance Technician (AMT)
