Top 10 Questions for Helicopter Mechanic Interview

1. During your helicopter inspection, you noticed a small crack on the main rotor blade. What steps would you take next?

• First, I would assess the severity of the crack and determine if it is safe to continue flying.
• If it is safe to continue flying, I would immediately notify the pilot and maintenance personnel.
• I would then coordinate with maintenance personnel to schedule a time to repair or replace the blade.
• If the crack is severe, I would immediately ground the helicopter and notify the pilot and maintenance personnel.
• I would then coordinate with maintenance personnel to have the blade repaired or replaced as soon as possible.

2. How would you troubleshoot a hydraulic leak in a helicopter’s flight control system?

• First, I would visually inspect the system for any obvious leaks.
• If no leaks are found, I would use a pressure gauge to check the system pressure.
• If the pressure is low, I would then use a stethoscope to listen for any leaks.
• Once the leak is found, I would then repair or replace the faulty component.

• In addition to the above steps, I would also consult the helicopter’s maintenance manual for specific troubleshooting procedures.
• I would also keep a record of all troubleshooting and repair work performed.

3. What is the importance of proper lubrication in a helicopter’s engine?

• Proper lubrication is essential for the proper functioning of a helicopter’s engine.
• It reduces friction between moving parts, prevents wear and tear, and helps to dissipate heat.
• Without proper lubrication, the engine would quickly overheat and fail.

4. What are the different types of inspections that are performed on helicopters?

• There are several different types of inspections that are performed on helicopters, including:
• Pre-flight inspections
• Post-flight inspections
• Daily inspections
• Weekly inspections
• Monthly inspections
• Annual inspections
• Major inspections

5. What are the most common causes of helicopter accidents?

• The most common causes of helicopter accidents are:
• Pilot error
• Mechanical failure
• Weather conditions
• Terrain
• Other factors

6. What are the different types of helicopter rotors?

• There are two main types of helicopter rotors:
• Main rotors
• Tail rotors

subheading of the answer

• Main rotors provide the lift that keeps the helicopter in the air.
• Tail rotors counteract the torque produced by the main rotors and prevent the helicopter from spinning.

7. What are the different types of helicopter transmissions?

• There are two main types of helicopter transmissions:
• Main transmissions
• Tail rotor transmissions

subheading of the answer

• Main transmissions transfer power from the engine to the main rotors.
• Tail rotor transmissions transfer power from the engine to the tail rotor.

8. What are the different types of helicopter engines?

• There are two main types of helicopter engines:
• Reciprocating engines
• Turbine engines

subheading of the answer

• Reciprocating engines are similar to the engines found in cars and trucks.
• Turbine engines are more powerful and efficient than reciprocating engines.

9. What are the different types of helicopter airframes?

• There are two main types of helicopter airframes:
• Rigid airframes
• Semi-rigid airframes

subheading of the answer

• Rigid airframes are made of metal or composite materials.
• Semi-rigid airframes are made of a combination of metal and composite materials.

10. What are the different types of helicopter flight controls?

• There are three main types of helicopter flight controls:
• Cyclic controls
• Collective controls
• Rudder controls

subheading of the answer

• Cyclic controls are used to control the helicopter’s pitch and roll.
• Collective controls are used to control the helicopter’s altitude.
• Rudder controls are used to control the helicopter’s yaw.

Helicopter Mechanics are responsible for maintaining and repairing helicopters, ensuring their airworthiness and safety. Their key responsibilities include:
