Having adopted a multitude of alterations to improve their overall efficiency and power, aircraft have come a long way since the first stable flight by the Wright Brothers in 1903. Whereas early airplanes could support only a couple people, modern commercial airliners are substantial enough to carry hundreds. As such, you may have wondered at some point “how many parts are there in an aircraft?” For most of today’s commercial planes, the answer is in the millions. With safety and efficiency as a topmost priority in aircraft construction, each airplane is painstakingly assembled through various levels, such as wire and cable shop, paneling, wing assembly, and paint application. Though there are far too many parts to list individually, many of them can be categorized into five major areas, those of which are the fuselage, wings, engine, landing gear, and stabilizers.
