Con tutta la fede che posso avere nel costruttore, qui la faccenda è differente Bourne: abbiamo sostanzialmente l'intera flotta di 787 messa a terra dalle autorità, si "salvano" Ethiopian, LOT (al primo giorno di impiego sul LR) e Qatar. La questione non è di poco conto.

787 battery in Japan sprayed hot chemicals
http://seattletimes.com/html/businesstechnology/2020149011_787batterydamagexml.html
Gooey dark residue was left around the battery on the 787 Dreamliner in this week’s emergency landing, suggesting a different malfunction than last week’s 787 battery fire in Boston.
Hot chemicals sprayed out of the battery on the 787 Dreamliner in this week’s emergency landing in Japan, leaving a gooey dark residue and suggesting a different malfunction than last week’s 787 battery fire in Boston, according to two people with knowledge of the situation.
The residue covered the battery and splattered over nearby instruments inside the forward electronics bay. It left a 12-foot-long dark streak from the battery to an outflow valve through which some of the spray vented overboard during the flight.
The people with knowledge of what was found inside the forward electronics bay after the incident said the battery was not blackened and cracked open like the battery in the Japan Airlines 787 fire a week earlier at Logan airport in Boston.
“It’s not as bad as the earlier incident,” one person said, speaking on condition of anonymity. “It looks like there wasn’t a fire. But there was a significant overheating.”
Two further sources confirmed that there was no fire inside the airplane.
The residue may have been from smoke or from hot, vaporized electrolyte, the potentially flammable chemical inside the battery.
But even without a fire, “it’s still a problem” that the electrolytes sprayed out of the battery box, said one person.
Four independent control circuits govern how the battery charges, ensuring that it neither over-charges nor discharges too much.
Boeing believes these circuits may have done their job as designed and stopped the overheating before a fire could start, one person said.
Boeing senior vice president Mike Sinnett, who is responsible for the plane’s electrical systems, said in an interview last week following the Logan fire that those controls, two inside the battery and two external, would prevent any serious battery incident.
He added that Boeing tests showed that any smoke from a less serious battery overheating incident in flight would exit through the outflow valves overboard, ensuring none entered the passenger cabin or the cockpit.
But the Federal Aviation Administration (FAA), announcing its decision Wednesday to ground the 787 fleet, indicated it is not satisfied that these systems worked as designed. It stated that both battery incidents resulted in the “release of flammable electrolytes, heat damage, and smoke.”
ANA said Wednesday that the pilots did smell something that they thought was smoke, and that this smell was also in the passenger cabin.
That, along with warnings of battery trouble on the instrument panel, is what impelled the pilot to make the emergency landing, deploy the emergency exit slides and evacuate all 137 passengers and crew.
Two people with knowledge of what happened said the pilot received three battery warning messages during take-off after an initial status message.
One of those messages warned that the battery was overheating.
The battery is made by GS Yuasa of Japan. Its manufacturing processes will likely be the immediate focus of attention once investigators learn precisely what went wrong in each of the two incidents.

Un disastro! In termini commerciali, per fortuna..
Devo pero' aggiungere che lasciare a terra le macchine per il volo di rientro, come ha fatto Qatar a Londra e Lot a Chicago mi sembra piuttosto azzardato..
A meno che non abbiano informazioni riservate
Ps : le batterie Gs Yuasa le ho sulla mia moto... Che sia il caso di fermarla?

Brutta bestia le batterie ad ioni di litio. Fanno risparmiare un sacco di peso, ma hanno la cattiva abitudine di fare casino in ogni modo possibile ed immaginabile (soprattutto in caso di carica eccessiva, ma Boeing da questo punto di vista si è protetta con una marea di circuiti elettronici). Ormai è una tecnologia abbastanza matura, ma i problemi non sono stati risolti del tutto, per cui potrebbero essere irrisolvibili a costi ragionevoli.
Piccolo OT per sorridere un pò

Questo il motivo:
European regulator EASA has become the latest aviation safety agency to order a grounding of Boeing's 787 in the light of problems with its lithium-ion batteries.
EASA adopted the US FAA's emergency airworthiness directive on 17 January.
It affects the two Dreamliners operated by LOT Polish Airlines.
"[EASA] continues to carefully monitor the situation and is prepared to provide any support the FAA may require in their investigation."

Non lo escluderei, tra l'altro secondo me non hai nemmeno gli scivoli. Io sulla mia ho la Exide al gel e sono a posto.
A parte le battute vedo una bella botta per Boeing, dopo tutti i problemi già avuti nello sviluppo e nell'inizio delle consegne. D'accordo che è un aereo nuovo, che ha una tecnologia molto avanzata, ma le batterie agli ioni di litio non sono proprio una novità....

Anche Qatar ed Ethiopian hanno deciso di sospendere i voli con 787.
In seguito alle direttive emesse dalla Federal Aviation Administration (FAA) e dalla Civil Aviation Authority del Qatar, Qatar Airways ha deciso di fermare le operazioni con i suoi cinque velivoli Boeing 787 Dreamliner a partire da oggi.
Il CEO di Qatar Airways, Akbar Al Baker, ha detto: “In precedenza avevo dichiarto che Qatar Airways avrebbe fermato le operazioni dei nostri Dreamliner solo se avessimo ricevuto una simile richiesta dalle autorità di regolamentazione. La sicurezza resta la priorità numero uno per Qatar Airways. Garantiamo che tutti i nostri aerei soddisfano gli standard di sicurezza più rigorosi e questo non sarà in alcun modo compromesso. Alla luce dei recenti avvenimenti che riguardano in tutto il mondo il Boeing 787 Dreamliner, stiamo lavorando attivamente con Boeing e le autorità di regolamentazione per ripristinare la piena fiducia del cliente nel 787. Qatar Airways riprenderà operazioni con 787 quando saremo certiche l'aeromobile soddisfa tutti i requisiti della direttiva di aeronavigabilità e le norme che garantiscono la sicurezza dei nostri passeggeri e dell'equipaggio in ogni momento. Quindi non faremo volare l'aereo fino a quando, e solo allora, questo scopo non sarà raggiunto. Qatar Airways desidera esprimere le proprie scuse ai passeggeri prenotati sui nostri voli con 787,ma siamo sicuri che capiranno le nostre preoccupazioni alla luce dei recenti avvenimenti con altri 787 operatori di tutto il mondo. Il nostro personale assisterà tutti i passeggeri interessati affinché siano ospitati su altri voli per arrivare alla loro destinazione finale con il minimo disagio."

In seguito alle direttive della Federal Aviation Administration (FAA), anche Ethiopian ha deciso di sospendere provvisoriamente le operazioni con i suoi B787 Dreamliner a scopo precauzionale.
"I Dreamliner di Ethiopian non hanno riscontrato problemi del tipo di quelli registrati dagli altri operatori," afferma una nota della compagnia aerea africana. "Tuttavia, come misura di sicurezza e precauzione extra e in linea con il suo impegno di porre la sicurezza soprattuto, Ethiopian ha deciso di mettere fuori dalle operazioni i suoi quattro Dreamliner e di seguire gli speciali requisiti di ispezione richiesti dalla FAA statunitense."
Nella nota Ethiopian, che ha in flotta i Dreamliner dallo scorso agosto, ha sottolineato comefinora i velivoli hanno volato senza alcun problema raggiungendo anche una serie di record. Dalla consegna del primo 787 la flotta di Dreamliner di Ethiopian ha raggiunto 5.560 ore di volo con un utilizzo medio giornaliero di 14 ore. La compagnia ha confermato di collaborare con Boeing al fine di conformarsi con quanto previsto dalla direttiva e di riportare quanto prima i suoi 787 in servizio.

con questa oramai globale sospensione di voli , per curiosità , è da prevedere una doverosa rivalsa delle compagnie nei riguardi della Boeing
