the Herald.net article states:
Boeing said last week it won't deliver more 787s until the U.S. Federal Aviation Administration instructs it on how to prove the Dreamliner's flammable lithium-ion batteries are safe.
. Interesting concept. The FAA does not instruct the OEM how to comply... that is the OEM's job to show compliance, or an equivalent safety finding, or to justify a special conditionbeing approved by the RA.
The B787 Type Certificate FAA TCDS T00021SE/EASA.IM.A.115 section 5, Special Conditions, has certificate review item (CRI) F24, Lithium Ion Batteries which is the area of interest at present. Would think that the FAA would be disinclined in accepting on face value the assumptions of fitness for service and risk analysis (25.1309) on a basis consistent with the good old risk matrix (MIL STD 882D).
