Top 10 Questions for Aircraft Sheet Metal Mechanic Interview

1. Can you explain the process of riveting on an aircraft skin?

• The first step is to select the correct rivet and drill a hole.
• Countersink the hole.
• Place the rivet in the hole.
• Buck the rivet head.
• inspect the rivet.

2. What are the different types of aircraft skin materials and their applications?

Aluminium Alloys

• 2024-T3 – high strength, used in stressed skin applications
• 7075-T6 – high strength, used in highly stressed areas

Composite Materials

• Carbon Fiber Reinforced Plastic (CFRP) – lightweight, high strength, used in leading edges and control surfaces
• Glass Fiber Reinforced Plastic (GFRP) – lightweight, corrosion resistant, used in fairings and cowlings

3. What are the different types of aircraft structures and their design considerations?

• Monocoque – a single, stressed skin that carries all the loads
• Semi-monocoque – a stressed skin supported by internal frames
• Truss – a framework of interconnected struts and spars

4. What are the different types of aircraft fasteners and their applications?

• Rivets – permanent fasteners used to join metal sheets
• Bolts – temporary fasteners used to join thicker sections
• Pins – used to secure hinges and other movable parts

5. What are the different types of aircraft welding processes and their applications?

• Gas Tungsten Arc Welding (GTAW) – used to weld thin sections of stainless steel and aluminum
• Gas Metal Arc Welding (GMAW) – used to weld thicker sections of steel and aluminum
• Electron Beam Welding (EBW) – used to weld critical components made of titanium and other exotic materials

6. What are the different types of aircraft coatings and their applications?

• Primer – provides corrosion protection and adhesion for subsequent coatings
• Paint – provides color and protection from UV radiation
• Sealant – prevents moisture and contaminants from entering the aircraft structure

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

• Pre-flight inspection – a visual inspection performed before each flight to identify any obvious defects
• Periodic inspection – a more detailed inspection performed at regular intervals to identify any potential problems
• Major inspection – a comprehensive inspection performed every few years to ensure the aircraft is in good condition

8. What are the different types of aircraft maintenance tasks and their frequency?

• Line maintenance – minor maintenance tasks that can be performed on the flight line, such as changing tires and fluids
• Base maintenance – more complex maintenance tasks that require the aircraft to be brought to a maintenance facility, such as replacing engines and repairing structural damage
• Overhaul – a complete disassembly and rebuild of the aircraft that is performed every few years

9. What are the different types of aircraft maintenance records and their importance?

• Logbook – a record of all maintenance performed on the aircraft
• Maintenance Manual – a detailed set of instructions on how to perform maintenance tasks on the aircraft
• Airworthiness Directive – a directive from the aviation authority that requires certain maintenance tasks to be performed on the aircraft

10. What are the different types of aircraft safety regulations and their importance?

• Federal Aviation Regulations (FARs) – regulations set by the Federal Aviation Administration (FAA)
• Air Transport Association (ATA) Standards – standards set by the Air Transport Association
• International Civil Aviation Organization (ICAO) Standards – standards set by the International Civil Aviation Organization
