"PickyPerkins", your link has nothing l believe, to do with this AD.
As l pointed out this MRB task and now being made into an AD, is all about air being sucked into the fuel tank piping from within the tank, from worn seals where the pipes join each other.
This happens with very low fuel state and would not happen just after take-off.
What happened to the UA aircraft, is l believe not related to this extra task introduced from the MRB and now mandated.
