The issue of Aviation Week dated tomorrow, January 14 has a fairly detailed article that explains much of the context for the special reviews now underway by the FAA and NTSB. The article itself is subscription only, but here is the link: http://www.aviationweek.com/awin/ArticlesStory.aspx?id=/article-xml/AW_01_14_2013_p19-534758.xml The gist is that in 2007 the certification of the B787 had numerous special conditions due to all the new technologies that are used. The electrical system is high among those because of the enormous amount of electrical power used by the airplane and the particular fact that the lithium-ion batteries were a big concern because of past fires in flight on aircraft carrying those batteries. Thus the JAL battery fire in BOS created an urgent requirement for review. Not mentioned in the article specifically but important to note: The fleet has NOT been grounded. Were there to have been an indication of serious inflight risk it certainly would have been. This is not a pleasant time for Boeing, but all the current indications are that the problems will be resolved soon. The biggest question, it seems, is whether the lithium-ion batteries will actually get a clean bill of health.
