What is the primary purpose of an airframe in an aircraft?
The airframe provides structural support and houses critical systems, ensuring aerodynamic efficiency and safety.
Which material is commonly used in modern airframe construction due to its high strength-to-weight ratio?
Composite materials like carbon fiber are widely used for their lightweight and durable properties.
What is the function of a wing spar in the airframe?
The wing spar is a critical load-bearing component that supports aerodynamic and gravitational forces.
Which regulatory body in the U.S. sets airframe maintenance standards for civil aircraft?
The FAA ensures compliance with safety and maintenance regulations for airworthiness.
What is the purpose of corrosion prevention in airframe maintenance?
Corrosion weakens structural integrity, so prevention is key to ensuring long-term airworthiness.
Which inspection method is used to detect cracks in airframe components without disassembly?
NDT methods like dye penetrant inspection help identify flaws without damaging the structure.
