It seems it would be an emergency AD note with a 'replace before further flight' restriction. If the oxygen line does turn out to be a factor the airline will get tagged for not changing the line, Boeing will get tagged for installing the defective line it in the first place, and the FAA will get tagged for the 18 month compliance window. If I were a pilot on the 777 I would make extremely sure the lines had been changed out. Before further flight
The O2 line theory is a very nice theory. So is the suicide theory. And the terrorist theory. And the black hole theory.
One must assume that some 777s are undergoing AD 2012-13-05 as we speak. Have there been any that have shown evidence of friction or wear. If so, I will gladly join your call to ground all 777 aircraft if not, I can wait.
I will concur that all civil aviation agencies recommend Black Hole avoidance; if avoidance is not possible minimize exposure should one pop up along your flight path; do not fly directly into a black hole.
