When I was flight instructing I did a whole presentation on airworthness. All the definitions. I liked to get AC43 out and show the plane owners / students all the maintenance a polite owner can perform. For example, a plane owner can change a flexable line but not a rigid one. This is a area of knowledge that is neglected and needs to be expanded. I had to go to Mexico one time to get a plane cause the pilot flew it down there with the small "N"s. Lot to learn in this area.
Young lady has a great question, the type of curiosity that makes a fine aviator
