Romulus;
Undoubtedly Boeing did their testing . . .
I expect that that question will be part of the investigation prior to re-certification of the B787. From the
NYT this morning (Jan 19, 2013 10:54 EST:
The government approved Boeing's use of lithium-ion batteries to power some of the plane's systems in 2007, but special conditions were imposed on the plane maker to ensure the batteries would not overheat or ignite. Government inspectors also approved Boeing's testing plans for the batteries and were present when they were performed.
Even so, after the episode in Boston, the federal agency said it would review the 787's design and manufacturing with a focus on the electrical systems and batteries. The agency also said it would review the certification process.
The FAA approval of Boeing's use of Li-Ion batteries is in the following document. One would expect that Boeing's testing and results will be examined against the FAA approval.
Special Conditions: Boeing Model 787–8 Airplane; Lithium Ion Battery Installation
AGENCY: Federal Aviation Administration (FAA), DOT.
