What is the most important part of an airplane?
The wing spar. The spar is the main structure of the wing that supports the load of the entire airplane. All the loads go through the wing into the wing spar and down to the center of it, which is called the "wing box". (You could call this the most important part,) An airplane may fly without its engines. It might be able to fly without its flight controls. But it can not fly if the wing spar breaks.
