Top 10 Questions for Airplane Mechanic Apprentice Interview

1. Explain the process of troubleshooting an electrical system on an aircraft?

• First, I would visually inspect the system for any obvious damage or loose connections.
• Next, I would use a multimeter to test the voltage and continuity of the circuits.
• If I found any problems, I would then use a schematic diagram to trace the circuit and identify the faulty component.
• Finally, I would replace the faulty component and test the system to make sure it is working properly.

2. Describe the different types of aircraft hydraulic systems and their functions?

There are two main types of aircraft hydraulic systems: open-center and closed-center.

Open-center systems

• Open-center systems are the most common type of hydraulic system used in aircraft.
• Open-center systems use a pump to continuously circulate hydraulic fluid through the system.
• The pump is constantly running, even when the hydraulic system is not in use.
• Open-center systems are relatively simple and inexpensive to maintain.

Closed-center systems

• Closed-center systems are more efficient than open-center systems.
• Closed-center systems use a pump to pressurize the hydraulic fluid only when it is needed.
• When the hydraulic system is not in use, the pump is turned off.
• Closed-center systems are more complex and expensive to maintain than open-center systems.

3. How would you inspect an aircraft landing gear for damage?

To inspect an aircraft landing gear for damage, I would first look for any obvious signs of damage, such as cracks, dents, or corrosion.

• I would then use a flashlight to inspect the landing gear more closely for any hidden damage.
• I would also use a borescope to inspect the inside of the landing gear for any damage that is not visible from the outside.
• Finally, I would use a torque wrench to check the tightness of all the bolts and nuts on the landing gear.

4. What are the different types of aircraft engines and their advantages and disadvantages?

There are two main types of aircraft engines: piston engines and jet engines.

Piston engines

• Piston engines are the most common type of engine used in small aircraft.
• Piston engines are relatively simple and inexpensive to maintain.
• Piston engines are not as powerful as jet engines, but they are more fuel-efficient.

Jet engines

• Jet engines are more powerful than piston engines, but they are also more complex and expensive to maintain.
• Jet engines are more fuel-efficient than piston engines at high speeds.

5. How would you troubleshoot a problem with an aircraft’s flight control system?

• First, I would visually inspect the flight control system for any obvious damage or loose connections.
• Next, I would use a multimeter to test the voltage and continuity of the circuits.
• If I found any problems, I would then use a schematic diagram to trace the circuit and identify the faulty component.
• Finally, I would replace the faulty component and test the flight control system to make sure it is working properly.

6. What are the different types of aircraft maintenance inspections and their purposes?

There are three main types of aircraft maintenance inspections:

• A inspections are the most basic type of inspection and are performed every 50 flight hours.
• B inspections are more comprehensive than A inspections and are performed every 100 flight hours.
• C inspections are the most comprehensive type of inspection and are performed every 200 flight hours.

7. How would you perform a weight and balance check on an aircraft?

• First, I would gather the aircraft’s weight and balance data.
• Next, I would weigh the aircraft using a calibrated scale.
• I would then use the aircraft’s weight and balance data to calculate the aircraft’s center of gravity.
• Finally, I would compare the aircraft’s center of gravity to the allowable center of gravity range.

8. What are the different types of aircraft fuel systems and their components?

There are two main types of aircraft fuel systems: gravity-feed systems and pressure-feed systems.

Gravity-feed systems

• Gravity-feed systems are the simplest type of fuel system and are used in small aircraft.
• Gravity-feed systems use gravity to move fuel from the fuel tank to the engine.
• Gravity-feed systems are relatively simple and inexpensive to maintain.

Pressure-feed systems

• Pressure-feed systems are more complex than gravity-feed systems, but they are also more efficient.
• Pressure-feed systems use a pump to move fuel from the fuel tank to the engine.
• Pressure-feed systems are more expensive to maintain than gravity-feed systems.

9. How would you troubleshoot a problem with an aircraft’s electrical system?

• First, I would visually inspect the electrical system for any obvious damage or loose connections.
• Next, I would use a multimeter to test the voltage and continuity of the circuits.
• If I found any problems, I would then use a schematic diagram to trace the circuit and identify the faulty component.
• Finally, I would replace the faulty component and test the electrical system to make sure it is working properly.

10. What are the different types of aircraft instruments and their functions?

There are many different types of aircraft instruments, each with its own specific function.

• Airspeed indicator measures the aircraft’s speed relative to the air.
• Altimeter measures the aircraft’s altitude above sea level.
• Attitude indicator measures the aircraft’s pitch and roll.
• Compass measures the aircraft’s heading.
• Engine instruments measure the engine’s performance, such as RPM and temperature.
