The attachment is an amendment to the original emergency AD. It permits any faulty pumps to be left in situ (presumably as long as the new flight limitations are adhered to).
Maybe I’m missing something, but this would seem to me to be more than just a bit cavalier.
What’s going to happen if the aircrew accidentally overlook switching a pump off before the fuel level drops below the safe level?????? Auto-ignition??
