When something breaks on the F-35, it takes the Pentagon an average of 141 days to repair it.

That sounds bad, but it’s also completely out of context. Commercial jets probably stay grounded less than a day, but I have no frame of reference for fighter aircraft.

I watched a video about maintenence for commercial passenger jets recently. Light engine maintenence takes on the order of a week, heavy maintenence takes several months. For heavy maintenence, they literally disassemble every component of the engine, so even if everything goes perfectly, it still takes forever.

That said, I imagine they just swap a new engine into the plane while the old one is under maintenence.

  Do you have a link to said video? Not because I disagree but because that sounds super interesting to watch.
