two serious battery problems caused the faa to ground boeing s new 787 dreamliner. some critics say the agency did not act fast enough to respond to those issues. peter doocy is looking at it live from washington. so have investigators, peter, been able to figure out why these batteries were catching fire? reporter: no, jon. the ntsb is still working on that at their materials lab in d.c. where they disassembled the lithion ion battery that caused the fire in boston two weeks ago. so far we ve only received three updates on their investigation and it sounds like they re using the process of elimination to find out what s wrong because the latest thing they ve crossed off their list of possible problems is excess voltage. in a statement today, the ntsb says, and this is a quote, examination of the flight recorder data from the jalb 787 airplane indicates that the apu battery did not exceed its designed voltage of 32 volts and boeing said they are not going
to speculate about what s wrong with their batteries until the faa finishes its investigation. jon, you see the batteries there. yeah. so how much longer will the airplanes stay grounded? reporter: there s no time table for that right now officially, but governments around the world told airlines using these enormous aircraft, these enormous 787s to keep them grounded to make sure these batteries don t cause any more smoke damage or worse and if you re wondering why they don t just swap these batteries out for some new ones that actually work, experts are saying that would not fly. any can t switch out to other kinds of batteries. that would really add too much weight and they wouldn t be able to produce the amount of power necessary to drive this aircraft. reporter: boeing says they are still confident in the overall integrity of the 787. jon? peter doocy in washington. thank you, peter. still to come, new details emerging on the state of americans in that a algerian
we ll tell you that story ahead. plus, the faa grounding all of boeing s 787 dreamliners after battery problems on two flights. what an examination of the flight recorders revealed straight ahead. [ male announcer ] wouldn t it be cool if we took the already great sentra apart and completely reimagined it with best-in-class combined mpg and more interior room than corolla and civic and a technology suite with bluetooth, navigation, and other handy stuff? yeah, that woulde cool. introducing the all-new nissan sentra. it s our most innovative sentra ever. nissan. innovation that excites. now get a $169 per month lease on a new nissan sentra, plus $500 holiday bonus cash. gives you 1% cash back on all purchases, plus a 50% annual bonus. and everyone but her likes 50% more cash,
these are the charred remains of the battery that started the fire in boston two weeks ago and caused smoke damage to a flight. it s interesting. this 787 dream liner program was actually launched back in 2004 with an order from the airline, but their dream liners and everyone else s dreamliners have been grounded by governments around the globe. experts are saying the only way to get these planes air worthy again is to fix the faulty batteries. they can t switch out to other kinds of batteries. that would really add too much weight and they wouldn t be able to produce the amount of power necessary to drive this aircraft. reporter: now, boeing refused earlier this week to speculate about what the issue is with the batteries, but they made clear that despite the problems, they think the 787 is safe and they stand behind its overall integrity. john? let s hope they get it fixed. peter doocy, thank you. well, president obama may be
certainly more to the store, and when we get it, we ll share it with viewers. we re getting new information right now about the string of problems that forced airlines around the world to ground boeing s brand new dream liner jets. the national transition safety board is ruling out excess voltage in battery fire on board a 787 in boston earlier this month. you might have seen that on happening now. peter doocy is live in washington with an update for us. peter? reporter: john, to figure out why these lithium ion batteries were leaking electri leaking el, the ntsb brought the ballotries to their lab to disassemble them. some have been speculating excess voltage could have started the fire but the ntsb told us today, but examination of the flight recorder from the jalb 787 airplane indicate the batteries did not exceed the designed voltage of 32 volts.
