A term used to refer to the two main components of an aircraft.

• "Airframe" refers to the physical structure of the aircraft, including the fuselage, wings, tail, and control surfaces. It is the main body of the aircraft that provides the overall shape and structure.
• "Power plant" refers to the engine or engines that provide the power to propel the aircraft. This includes the engine itself, as well as the propellers, turbofans, or other components that generate thrust.

Together, the airframe and power plant work together to enable the aircraft to fly. The airframe provides the structure and shape that allows the aircraft to withstand the stresses of flight, while the power plant provides the power needed to generate lift and thrust.

In the context of aircraft maintenance, the term "airframe and power plant" is often used to refer to the overall maintenance and inspection of the aircraft, including both the structural components and the engines.
