Default Is the 787 a failure ?

Discussing an NTSB meeting to be held on 23,24 April:
|
| National Transportation Safety Board (NTSB) chief Deborah
| Hersman said Friday an upcoming hearing should reveal "a
| lot more about the certification and design process" that
| Boeing and aviation regulators used for the 787 Dreamliner
| battery system before it went into service.
|
| After that, she said in an interview, "If we believe there
| are changes that need to be made, we will pursue that."
|
| Hersman said the NTSB will review Boeing's design and risk
| analysis and the Federal Aviation Administration's
| certification process in its final investigation report,
| which should be issued by the end of the year.
| ...
| She declined to comment specifically on Boeing's proposed
| battery fix. The NTSB is charged with assessing safety and
| making recommendations, but the FAA sets the rules of
| aviation, and it's the agency that grounded the Boeing jets.
|
| "Boeing has to identify and properly mitigate the risks to
| the FAA's satisfaction," Hersman said. Lifting the
| grounding "really is up to the FAA."
| ...
| Hersman acknowledged that it's a challenge to identify the
| root cause of the internal short known to have started the
| Boston battery fire because the battery was severely
| damaged.
|
| In searching for that cause, her experts are conducting
| weeks-long tests on other batteries produced by Boeing's
| supplier, GS Yuasa of Japan.
|
| "We have to let the investigation play out," Hersman said.
