Common materials in aircraft structures include aluminum, which is lightweight and has good corrosion resistance, titanium known for its high strength and heat resistance, and composite materials that offer great strength-to-weight ratios. For example, aluminum is primarily used for fuselage and wing structures, while composites are often used in modern aircraft for components like wing skins.

I would first assess the extent of the damage to determine the repair method. Then, I would gather the necessary materials, such as composite patches or aluminum sheets, and the tools needed for the job. Following the manufacturer's repair manual, I would clean the area, remove the damaged skin, and prepare the surface before installing the new skin, ensuring all fasteners are secured properly.

To conduct a thorough inspection, I begin by reviewing the maintenance manual to understand the necessary procedures. Then I perform a visual inspection to check for any obvious signs of damage or corrosion. Next, I use tools like ultrasonic testing to ensure material integrity, and document everything I find for records. Finally, I make sure to address any repairs needed based on my findings.

Key FAA regulations for aircraft structure maintenance include 14 CFR Part 43, which covers maintenance, preventive maintenance, and alterations, and Part 91, which ensures the safe operation of aircraft. Additionally, I keep up with the applicable airworthiness directives that specifically address structural integrity.

I use a rivet gun for fastening structural components, ensuring strong joints during repairs. A torque wrench is essential for applying the correct torque to bolts on critical structures. I also rely on borescopes for inspecting internal structures without disassembly.

Stress is the force applied per unit area within materials, while strain is the deformation experienced by the material in response to that stress. In aircraft structures, high stress concentrations can lead to failures, so we measure stress using units like Pascals. Understanding this helps engineers ensure the aircraft can withstand various forces during flight.

I have worked extensively with carbon fiber and fiberglass composites in aircraft structures. I trained in composite repair techniques, focusing on bonding and using vacuum bagging methods for repairs. One project involved successfully patching a carbon fiber wing surface that had been damaged during landing, following all safety protocols.

Aircraft structures commonly use different fasteners including bolts, nuts, and rivets. Bolts are often made of titanium for strength and lightweight, while rivets may be aluminum for corrosion resistance. It's important to reference specifications like AN and NAS to ensure quality and safety in assembly.

I start by identifying key symbols and terminology to understand the drawing's context and then check the scales to ensure accuracy in measurement.

Maintaining accurate logs is crucial for safety, as it ensures that all repairs and inspections are properly documented. This helps in guaranteeing compliance with FAA regulations and ensures that we have a complete history of maintenance which is vital for safe operations.

In aircraft structure repairs, we commonly use TIG welding for aluminum components due to its precision and control. MIG welding is also employed but is less common for critical structural repairs.
