Overdid the weight reduction, perhaps?

That's very aerospace. But when something bumps an aircraft, it gets maintenance and even slightly damaged parts get replaced.

>even slightly damaged parts get replaced.

Usually but not always. It's true that aircraft demand much more diligent maintenance than terrestrial vehicles though.

There are provisions in most maintenance programs for deferring repairs on minor damage and/or what's called a minimum equipment list that outlines what can be broken and still let you fly legally.
