Airframe Knowledge Base | Learn Aircraft Structures and Systems

The Airframe section provides the essential knowledge and skills required for the inspection, maintenance, and repair of an aircraft’s structural and mechanical systems. It introduces the principles, components, and procedures that form the foundation of the Airframe Mechanic rating, supporting both classroom instruction and independent study.

This section covers a wide range of topics including aircraft structures, control systems, landing gear, hydraulic and pneumatic systems, environmental controls, and other components that make up the aircraft’s physical framework. Since airframe designs and configurations vary among aircraft types, representative examples are used to illustrate key concepts throughout.

The content offers a broad technical overview and should always be used in conjunction with manufacturer’s manuals, official aviation regulations, and other reference materials for aircraft-specific information. It serves as a general guide to strengthen understanding before advancing into detailed maintenance procedures.
