Many years ago I used to work on Mirage fighter jets designed by Marcel Dassault. One of the jobs that was always very hard was removing the water separator in the aircon system. The maintenance manual basically said remove the panel, disconnect the fittings and remove the separator.
It never came out without an almighty struggle. One day when I had a bit of spare time I dug out the original French language manuals and checked the instructions, What they actually said was "Utilizing the natural elasticity of the airframe, remove the separator". So they knew it did not fit through the hole and needed lots of leverage.
Turns out that the University students that were paid to translate the manuals from French to Australian were pretty well overpaid.
