People
familiar with the investigation, however, said high-level Federal
Aviation Administration officials are increasingly concerned about the
spate of electrical problems, highlighted by the smoldering battery
aboard the JAL jet, that have dogged the aircraft since its
introduction.
No additional mandatory safety fixes or
government-ordered inspections of Dreamliners are expected for at least
the next day or two, partly because FAA and NTSB experts still are
trying to determine the specific cause of the battery fire. But perhaps
as soon as early next week, according to one person familiar with the
matter, regulators may call for some type of review or reassessment of
design and manufacturing issues related to the Dreamliner's electrical
systems.

FAA's Huerta: technical review to validate #787 certification data and focus on quality in design & production.
It is uncommon for the F.A.A. to open a review of an airplane it has
already certified, but it points to increased concern by regulators.
Industry and government officials said the Dreamliner is the only
commercial jetliner in decades to be subjected to such high-priority
regulatory scrutiny after being approved to carry passengers. The
Chicago-based plane maker fought unsuccessfully for days to head off or
deflect the announcement, according to people familiar with the details.
Friday's press conference also was unusual because Mr. Huerta and Mr.
LaHood were joined by Ray Conner, president of Boeing's commercial
airplane unit. Regulators seldom announce such a major safety initiative
flanked by the target of their review, let alone give company officials
a chance to defend their procedures and respond to questions from the
media.
Some safety experts say the review could at least open the door to
possible design or manufacturing changes that could hamper Boeing's
production and potentially increase costs. Before the announcement,
according to people familiar with the discussions, senior Boeing
officials complained vigorously to the FAA and DOT that launching a
review also could undercut passenger confidence in the planes.

The National Transportation Safety Board (NTSB) said Monday the intensely burned-out battery that caused a fire aboard a Boeing 787 Dreamliner a week ago is being examined at a lab in Washington, D.C.
After documenting the state of the airplane and removing the battery and other equipment for its investigation, the agency has now released the 787 back to Japan Airlines.
The NTSB said the battery was given an X-ray CT scan at an independent test facilty this weekend, which “allowed the team to document the internal condition of the battery prior to disassembling it” later this week, the agency said in an update on its inquiry into the fire.
Investigators also removed burned wire bundles from the jet for examination, along with the battery charger and several electronic control memory modules.
The NTSB update said its team “also documented the entire aft electronics bay including the ... battery and the nearby affected structure where components and wire bundles were located.”
The jet’s two combined flight data and cockpit voice recorders were transported to NTSB headquarters to determine if anything related to the incident occurred on the 12-hour, 20-minute flight from Tokyo that immediately preceded the fire.
The flight to Boston’s Logan International Airport landed less than half an hour before the fire broke out, though all 183 passengers and crew had disembarked.
The flight data is now being analyzed by the NTSB investigative team.
A separate NTSB team focused on the emergency response to the incident at Logan interviewed the firefighters and documented the airport rescue and firefighting efforts to extinguish the fire
The NTSB update said that though all “fire and rescue personnel responding to the incident had previously received aircraft familiarization training on the Boeing 787,” they “reported experiencing difficulty accessing the battery for removal during extinguishing efforts.”
Helping the NTSB with the investigation are Boeing, the FAA, Japan Airlines, battery maker GS Yuasa of Japan, battery and charger system supplier Thales of France, and the US Naval Surface Warfare Center’s Carderock Division in West Bethesda, MD.
Carderock is a Navy research and development, test and evaluation, engineering facility.
An All Nippon Airways Boeing 787 has made an emergency landing in Japan's Takamatsu airport after the flight crew observed an alert related to a battery.
All 129 passengers and eight crew aboard the aircraft were evacuated via slides, says an ANA spokesman.
"An error was coming up for a battery," says the spokesman. "So it was decided to make an emergency landing."
Media reports indicate that smoke was also observed in the aircraft's cabin, but the spokesman was unable to confirm this.
The aircraft, registration JA804A, was operating flight 692 on the
Yamaguchi-Ube to Tokyo Haneda route. The aircraft departed Yamaguchi-Ube
at 8 a.m. local time and made the emergency landing at 8:47 a.m.
Flightglobal's Ascend Online database shows that the 787, MSN 34486 was delivered to ANA in January 2012.
ANA operates 17 787-8s and has a further 19 on order, and 30 787-9s on order.
The news comes just one week after a battery fire aboard an Japan
Airlines 787 at Boston's Logan airport. The Boston fire was a major
driver of a US Federal Aviation Administraion review into the 787
announced on 11 January.
ANA said the smoke was in the cockpit and the pilot got a warning
signal indicating a battery problem, according to Japanese media.
Yuzuru Ogasawara, chief of the transport ministry’s Takamatsu
bureau, told Bloomberg News that the airport control tower “confirmed
the smoke.”
However, the local city fire department said there was no fire. An
ANA official said the airline canceled all Wednesday flights on its 17
Dreamliners.

At a news conference - where ANA's vice-president Osamu
Shinobe bowed deeply in apology - the carrier said instruments
on the flight indicated a battery error, triggering emergency
warnings to the pilots. It said the battery in the forward cargo
hold was the same type as one involved in a fire on another
Dreamliner at a U.S. airport last week.
"There was a battery alert in the cockpit and there was an
odd smell detected in the cockpit and cabin, and (the pilot)
decided to make an emergency landing," Shinobe said.
Marc Birtel, a Boeing spokesman, told Reuters: "We've seen
the reports, we're aware of the events and are working with our
customer."
A Boeing safety document from last year shows the location of the
battery in a lower compartment near the plane's tail section. The
compartment, which is not protected by the plane's fire-suppression
system, contains key electrical systems. The battery, which powers the
plane's auxiliary power unit, is close to the plane's fuselage.
“Later it was confirmed that the main battery in the forward electronic
equipment bay was discolored and the electrolysis solution had leaked.”
Les Boeing 787 Dreamliner cloués au sol
Publié le 17 janvier 2013 à 07h00 par François Duclos dans Actualité, Info pratique, Technologie - 0 commentaire
L’autorité américaine de l’aviation civile FAA a suspendu hier soir tous les vols en Boeing 787 Dreamliner jusqu’à ce que la fiabilité des batteries au lithium-ion soit prouvée, une décision suivie immédiatement par les autres pays.
La mesure annoncée par la FAA dans la soirée du 16 janvier 2013 ne concernait que la compagnie aérienne United Airlines,
seule américaine à avoir mis en service le dernier-né de Boeing (six au
total), mais elle a été immédiatement appliquée par la DGAC du Chili,
les deux 787 de LAN Airlines devant à leur tour être
immobilisés. Le régulateur américain estime que les défaillances de
batterie, rencontrées à deux reprises sur des Dreamliner de Japan Airlines puis All Nippon Airways, pourraient endommager les structures critiques et les systèmes, voire provoquer un incendie.
L’annonce a été faite suite à l’incident mercredi au Japon
d’un Dreamliner d’ANA, un atterrissage en urgence ayant été nécessaire
l’apparition de fumée due à une surchauffe de batterie. ANA et Japan
Airlines ont immédiatement suspendu tous leurs vols en 787 jusqu’à
aujourd’hui au plus tôt (elles en opèrent 24 sur les 50 en service),
annulant 38 vols pour la première et huit pour la seconde. Et le
gouvernement japonais a déclaré ce matin qu’il appliquera la directive
de la FAA.
L’Inde a suivi le mouvement, les six Dreamliner d’Air India
étant cloués au sol depuis ce matin après une enquête ordonné la veille
par le gouvernement. En Pologne le vol inaugural du 787 de LOT Polish Airlines
entre Varsovie et Chicago a décollé hier, mais les célébrations prévues
à l’arrivée ont été annulées, tout comme le vol retour. Les deux 787
avaient passé des vérifications hier selon le transporteur.
Pas de réaction officielle au Qatar à l’heure d’écrire ces lignes, mais les journaux australiens annonçaient ce matin que Qatar Airways repousserait le lancement du Dreamliner vers Perth, prévu en février. Ethiopian Airlines, qui a mis en service quatre 787, n’a pas communiqué depuis le dernier incident.
Boeing a réagi hier à la directive de la FAA par la
voix de son PDG Jim McNerney, qui s’est déclaré « confiant dans le fait
que le 787 est sûr », et mettra toutes les ressources de la compagnie au
service du régulateur et des compagnies « afin de trouver des réponses
le plus rapidement possible ». Tout en regrettant « l’impact des
évènements récents » sur les programmes de vol des clients et leurs
passagers.
