Top 10 Questions for Airplane Mechanic Interview

1. Describe the process of troubleshooting an aircraft electrical system?

• Begin by gathering information about the issue, including the symptoms and any recent maintenance or repairs.
• Inspect the electrical system for any obvious damage or loose connections.
• Use diagnostic tools to test and isolate the faulty component or circuit.
• Repair or replace the faulty component and test the system to verify the issue has been resolved.
• Document the troubleshooting and repair process in the aircraft maintenance log.

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

Open-center system

• Fluid continuously flows through the pump and back to the reservoir.
• Valves control the flow of fluid to the actuators.
• Used in systems where precise control of actuator movement is not required.

Closed-center system

• Fluid is pumped into a pressurized accumulator when not in use.
• When an actuator is activated, fluid is released from the accumulator.
• Used in systems where precise control of actuator movement is required.

3. What are the different types of aircraft landing gear systems?

• Fixed landing gear: Non-retractable, fixed in place during flight.
• Retractable landing gear: Can be retracted into the aircraft fuselage or wings during flight to reduce drag.
• Taildragger landing gear: The main wheels are located behind the center of gravity, with a smaller tail wheel at the rear.
• Tricycle landing gear: The main wheels are located in front of the center of gravity, with a smaller nose wheel at the front.

4. Describe the process of inspecting and maintaining aircraft brakes?

• Visually inspect the brakes for any signs of wear, damage, or contamination.
• Check the brake fluid level and condition.
• Test the brakes for proper operation and responsiveness.
• Lubricate and adjust the brakes as necessary.
• Document the inspection and maintenance findings in the aircraft maintenance log.

5. Explain the use of NDT (non-destructive testing) in aircraft maintenance?

• NDT techniques are used to inspect aircraft components for defects without damaging the component.
• Common NDT methods include ultrasonic testing, eddy current testing, and radiographic testing.
• NDT is used to detect defects such as cracks, corrosion, and delamination.
• Regular NDT inspections help to ensure the safety and reliability of aircraft.

6. Describe the different types of aircraft fuel systems and their components?

• Fuel tank: Stores the aircraft fuel.
• Fuel pump: Pumps fuel from the tank to the engine.
• Fuel filter: Removes contaminants from the fuel.
• Fuel line: Transports fuel from the tank to the engine.
• Fuel injector: Injects fuel into the engine cylinders.

7. Explain the principles of aircraft engine operation?

• Air is drawn into the engine through the intake.
• Fuel is injected into the air in the combustion chamber.
• An ignition source ignites the fuel-air mixture.
• The burning fuel-air mixture expands and drives the pistons.
• The exhaust gases are expelled from the engine through the exhaust system.

8. Describe the different types of aircraft navigation systems?

• VOR (VHF omnidirectional range): Provides directional information to aircraft.
• ILS (instrument landing system): Provides precise guidance to aircraft during landing.
• GPS (global positioning system): Provides accurate positioning and navigation information.
• Inertial navigation system (INS): Uses internal sensors to calculate the aircraft’s position and orientation.

9. Explain the principles of aircraft stability and control?

• Stability: The ability of an aircraft to return to equilibrium after a disturbance.
• Control: The ability of the pilot to maneuver the aircraft.
• The control surfaces (ailerons, elevator, rudder) are used to control the aircraft’s movement.
• The aircraft’s design and configuration contribute to its stability and control characteristics.

10. Describe the role of an aircraft mechanic in ensuring the safety of an aircraft?

• Performing regular inspections and maintenance tasks.
• Troubleshooting and repairing aircraft systems and components.
• Ensuring that all maintenance and repairs are documented and meet regulatory requirements.
• Working closely with pilots and other maintenance personnel to ensure the safe operation of the aircraft.
• Continuously updating their knowledge and skills to stay abreast of new technologies and safety procedures.
