    Does the FAA have the ability to enforce this on airlines operating outside the United States?

      No, not if they are not on the US register, but they'd be idiots to ignore it.

        Looks like enough have now followed their lead to grounding all 787s

            The oil leak is something overblown too. That, I'm willing to bet it was a maintenance issue. Probably just an overfill condition.

            That said, given all the redundancies that I've seen and are aware of on that plane, I still would say it's one of the safest planes to fly out there.
            While I've to agree with you on the windshield issue, the oil leak doesn't seem to be a minor issue.

            The plume of smoke from the exhaust clearly indicates a broken oil or hydraulic line. Maintenance could safely be ruled out from this case as one can safely assume that no engine components could have been changed on an aircraft this new.

            The batteries, lithium ion, are notorious for overheating issues. Lithium ion is the prime suspect in two recent freighter crashes and there was a renewed call to ban lithium ion to be shipped on board aircrafts. I find it ironic that the authorities have allowed Boeing to install lithium ion as a standard equipment despite its notoriety. Would FAA be bold enough to issue an AD to replace the Li-Ion batteries with conventional ones ?

            While no issues have cropped up yet so far, I strongly feel the extensive use of composites in fuselage construction is going to be an issue in the near future.

            Peace Out.

              Correct.

              Airlines must take safety issue seriously.

                Quite true...

                Considering that both hydraulics and Li ion batteries were sources of fires in this incidents, me thinks there may have been a close link in at least one case. And there have been warnings all over the place for consumer products using Li ion batteries over the years, so its not like they may not have known but Boeing may have been caught off guard by the lure of the long life of most of these batteries, despite transportation needing different types of power and far greater safety requirements compared to small consumer goods.

                And you're right that manufacturers should be wary of relying too much on composites.

                I agree that they REALLY should. These incidents have already soured the safety reputation of the 787 similar to the A380 after its string of problems, from QF's infamous engine blowout (and many other issues with Rolls Royce engines) to cracks in the wing. Needless to say though safety comes before any reputation.

                Oh, and after making repairs, they should make sure they don't have poor maintenance right?

                  The A380 was never grounded worldwide......or anywhere for that matter. Quick action by both Airbus and Rolls Royce did help in this regards, but the QF engine matter could have been very disasterous for all concerned, with a whole in a fully laden wing and seriously damaged hydraulics.

                  With regards these batteries, I too am susrpised at their use. I mean, if you can't even prevent an iPhone exploding (my colleague's did) the technology may not be the most suitable for such a critical environment. It was only a few months ago I got an email from CX explaining what precautions needed to be taken while transporting batteries on board so the airlines take it as an issue.

                  Finally, I don't believe composites will be a problem since it's not like we're talking about a $250 sail dingy or a 1980's kit car here. If done correctly I would have no fear flying in an older composite aircraft when the time comes later.

                    European community works quite different from American. As you can also see SQ works quite differently from QF. After the QF incident, QF grounded all A380 until investigation is completed. While SQ announced in the press their A380 is safe and checked (even some of them are still in the air !). Subsequently, these affected engines was replaced with 777 filing into A380 schedule.

                    So you can see even airlines handle the situation quite differently.

                          Composites in sail dinghies and cars merely act as cover from the elements and as an aerodynamic fairing for the said vehicles. They are not constantly exposed to forces up to tons. Composites in B787 has an important role as they have to withstand the pressure difference and the constant temperature fluctuation of its operating environment. Composites have been used in commercial aircraft before, but they have not been used to the extent as in B787.

                          Aluminum would show visual indications of weakness and ramp incidents, AKA ramp rash, in the form of dents. When picked up, structural repairs could be initiated to strengthen the affected area. Composites, on the other hand, do not show signs of knocks as well as aluminum due to their inherent stiffness.
                          A US agency had already raised its concerns on this before.

                            Mary Schiavo, a former DoT inspector general, said that the grounding is looking less likely to be days, "but possibly months"
                            There has been some commentary that the A350 may need to redesign their electrical system as a result of whatever ruling emerges from this as it also uses lithium ion batteries. She makes the point, that while this might be the case, at least Airbus will have the opportunity to fix it "behind closed doors"
                            If a complete overhaul of its electrical network is mandated, the cost savings B787 brings would be affected badly.
