View Through the Windows of Troubled Dreamliner

Everybody is in a hurry to find out what happened to two Boeing 787 Dreamliners and whether the world's newest airliner's in flight battery problems  can be easily fixed or if they signify some more serious problem with the design of the airplane that uses such a volatile energy source.  I'm among those impatient for answers, feeling some connection to the Japan Airlines Dreamliner which I had thrill of flying round trip Boston to Tokyo just 4 months ago.

Jim Blaszczak on the Dreamliner
But my eagerness can't match that of James Blaszczak, a United Airlines 787 pilot who was in Houston and ready to fly UA Flight 1489 on Wednesday when he learned of the FAA's action.  

"I was on the flight deck, briefing the flight when the purser came up and said she heard from the agent, the that the FAA had grounded the plane," he told me.  That fight and UA 33 onward to Tokyo would have been Jim's second Pacific crossing in the new plane. 

Jim's a regular reader of Flying Lessons, and a blogger himself, so we communicate frequently. He's a safety buff; a CRM trainer and a bit of a historian on the origin of threat and error management.  He is as familiar with the Dreamliner as any other pilot qualified to fly it, which is to say, he's no expert.  Since transitioning to the 787, he hasn't had any incidents and is one of those who find the airplane dreamy. 

Even so, before boarding the plane, he'd asked questions about the ANA emergency landing in Takamatsu, earlier that day so he would be ready for anything the flight attendants or passengers might want to know.

"I got a briefing from the company about what they had done to inspect, to ensure that what happened to ANA would not happen and they went over the systems with me."

But like every other Dreamliner operator that had not suffered an issue with the battery, United was baffled. It needed someone with the 40,000 foot perspective. Unfortunately, the pros with the long view - read the FAA, the DOT and Boeing - were too busy trying to convince an increasingly skeptical public that there was absolutely nothing wrong with the Dreamliner that a little shaking out wouldn't fix. What prompted them to come down from that tree, I can't say, but they've done the right thing now.

Of course, the NTSB, has been on the case since January 7th, when the first battery incident occurred on the JAL plane in Boston. This morning the safety agency announced that during that event, the APU battery did not exceed its designed limit of 32 volts. Battery cells, circuit boards and wiring from the lithium ion battery that caught fire on the JAL 787 are being examined six ways to Sunday by the NTSB materials laboratory

The NTSB announcement also shows incremental progress in that it has developed a "test plan" for how its probe will proceed. After the holiday, non volatile memory from the APU battery management unit will  be examined in Arizona and other components have been shipped back to Boeing in Seattle and the battery manufacturer, GS Yuasa in Japan. The announcement does not say, but one may assume this creates a path forward for  investigator Lorenda Ward and her team, who were sent to Takamatsu, Japan late last week to look at smoking battery number 2.

Two years ago, Capt. Blaszczak and I were debating the rules prohibiting the use of personal electronic devices below 10,000 feet and Jim wrapped up his email comment with a statement equally applicable to the Dreamliner situation. "Safety is always paramount in aviation because there are no do-overs," he wrote.  When it comes to aviation safety, decisions "must be made with a default to the conservative choice." 

He had the right idea then. He has the right idea now. 

Here's hoping it won't be too long before the conservative choice and the Dreamliner's return to the sky are on a parallel course.

Great post Christine and I believe you've outlines the issue(s) well. I am confident that the combined engineering and investigative forces of Boeing, FAA, NTSB, subcontractors and foreign authorities WILL find and correct any problems, probably sooner than later. I'm sure that Boeing has its best working on this and cost be damned; the very survival of their new airplane depends upon getting it, quickly. If the Lithium batteries get bumped in favor of an older technology and with some weight penalty, so be it.
You mentioned Captain Jim, preparing to take off for Japan when he learned that his airplane was grounded. What an awful way to get a day off! I visited his blog and read his most current (if stale?) post. Yup, a truly Safety-First fellow (and an excellent writer). Sadly, he does not post often. Given his recent transition to a very new type aircraft and his obvious bent for getting it right -The First Time- I can understand his lack of time for posting. As noted somewhere on his page, (to paraphrase), "... when flying airplanes, there are no Do-Overs..." That's the kind of driver that I want in row zero, seat A, the next time I fly. Regards, -C.

Christine, your interest on this issue and of spreading the word is admired and supported. I trust you will keep up the investigative side and report fearlessly.

I equally trust that Jim will keep his job and keep on blogging equally fearlessly.

The issue of the 787 Dreamliner,is the same issue that rules across all the aviation industry:Cognition
i.e. pilot's fatigue.If one does not sleep well,his decisions will be skewed.It is of no surprise to me that the current decision of the N.T.S.B.,is in putting the fault in possible overcharging the batteries.I disagree.As pilot
Blasczazck said:They do not think
at 40000 feet level.I have my"Two
cents"solution in this case.

IIRC from Physics 1b 60 years ago, it is current that causes overtemp, not voltage. Was there any record of the current draw on the circuit?

It intrigues me that certain freelance writers had previously described the Dreamliner as "beset with problems" - now it seems, it has only one problem. Facts please, cold and hard, not "spin".
