787 probe puts spotlight on Arizona battery firm
After the fire, a former Securaplane employee named Michael Leon filed a claim for federal whistleblower protection, alleging that he was fired for raising security concerns about the design of the charger and discrepancies between assembly documents for the chargers and the finished chargers.

787 probe puts spotlight on Arizona battery firm
"nestork" wrote in message
stuff snipped FAA spokeswoman Laura Brown said the FAA investigated Leon's complaints, but determined that the battery charging units that he addressed were prototypes, and none were installed in Boeing 787 aircraft. So, it's not like this Michael Leon fella got fired because he complained when he discovered the Securaplane company was doing something wrong. There's clearly something wrong the battery/charging combos. The Leon case is a lead in an investigation that's not yielded many facts so far. Will it pan out? Maybe not but it's unfortunate for Securaplane for this case to pop up right now. The article said that Leon's appealed the finding of the ALJ (not the brightest jurists in the land, typically) and has civil litigation underway. This case isn't likely to go away soon and I can easily see him getting a free first-class upgrade to a better attorney as a result of the publicity. I wish it were that simple so that Mr. Leon could simply tell Boeing what was done wrong and Boeing can finally solve the problem with the 787. I don't believe he's stated that he could solve the problem, just that Securaplane apparently can't properly test lithium battery assemblies without burning their office down. That's a pretty big clue. Unfortunately, this smells more like a case of Michael Leon getting himself fired, Fortunately the legal system doesn't run via smell. (-: The old saying "where there's smoke, there's fire" seems particularly appropriate to this case. and then as so often happens, the disgruntled employee then looking for a way to screw the company that fired him, and finding it in the whistleblower protection legislation. I've dealt with a fair number of wrongful termination, whistleblower and discrimination lawsuits. I readily agree that it's true that they are often used as "ways to screw the company." On the other hand, I've never seen an employer who's been sued or complained against paint that employee as a model worker. (-: What I have seen, and more often than you might think is that suddenly, people who had earned a huge bonus and a special award from the CEO last year are treated like Satan this year. Both sides have a history of playing dirty in these sorts of disputes. Each case has to be considered on the merits. Lithium batteries burn up far more often than other battery technologies so drawing attention to Securaplane's previous serious problems is probably a good thing, overall. Ask yourself what kind of testing lab is so poorly designed that a failed battery under test burns the building down? My hunch is that they are now wishing they had settled with this guy a long, long time ago because as Ricky used to say to Lucy: "Securaplane, you have some 'splaining to do!" The FAA person said something that's potentially misleading: "The U.S. Federal Aviation Administration (FAA) on Sunday said it had investigated safety complaints leveled by a former Securaplane employee in 2008 and 2009 but determined that the allegations focused on prototypes that were not ultimately used in the new lightweight airliner." We don't know, for example, if Leon was the employee mentioned above or if more employees were involved. We don't know how much of the design of the prototypes that were not "ultimately" used ended up in the final assembly. "Ultimately" here is another suspicious word - they were used at some point, apparently. When was the change? Were those units used in some other application not under the purview of the FAA? This is going to expand quite a bit more, I think, because there are so many questions raised by the fire and Leon's allegations. This happens all the time, it's just that Securaplane is under the spotlight as the company that made the charging system for the troubled 787, *Shouldn't* they be under the spotlight? From my knowledge of the many lithium battery fire lawsuits that have been brought, the causes are almost always overcharging or short circuits. YUASA, the battery maker, is also on the hot seat, but to a lesser extent, IMHO. Charging problems are usually the culprit when a battery assembly like the 787's catches fire, especially if there's no design flaw in the connectors and they can't be easily accidentally shorted. and so Michael Leon's case is getting far more notariety than most. The folks charged with designing a safe battery and charger burned their building down testing their designs. Should we trust them with a fleet of 787's? I wouldn't. But, I don't think they're going to find much more under this rock than notariety. I don't think "notoriety" is the right word. It means famous for doing something bad. "Dillinger was a notorious criminal." I don't think Leon qualifies. I'd say instead that Securaplane has endured bad publicity over this and will suffer quite a bit more. Leon's brought serious attention to the fact that Securaplane was not able to conduct safety tests safely. That sort of test shouldn't burn down a building. If I were on a civil jury hearing his case, I'd tend to side with Leon because that fire demonstrated incompetence. I'd want to look very carefully at his employment history to see if it supports the claim he was a terrible worker. Evaluations tend to get doctored up and commendations magically fall out of work history files to make the employee look like the world's worst. Doctored documents are often a source of victory for the employee because when fraud like that is revealed, it powerfully impeaches the employer. While many of these allegations are meant to strike back at former employers, I am sure you recall there were a number of engineers that made similar very serious complaints about defective O-rings and foam insulation shedding aboard the Space Shuttle. Sometimes mid-level engineers are forced to sign off on things that they just can't live with and they file complaints. No employer I know of takes that sort of action positively. Their SOP is "we'll handle this in-house" and then they forget about it. The story of the Challenger O-rings is a tragic reminder that not all allegations are retaliatory and that sometimes whistleblowers get it right - sadly sometimes too late to make a difference. The bottom line here could be that lithium technology is deemed unsuitable for aircraft use - for now - and that Boeing may have to use less explosive (but less efficient) alternatives. I'd have to look more closely at the available documents before I'd say it was a strike suit with no merit. Securaplane seems to have some serious safety problems. If they can't keep their offices from burning up should we really trust them to keep the 787 from burning up? FWIW, I've had a small lithium button cell short out and it sounds just like the crack of a .22 pistol. With all that lithium cells are exposed to on a jet (vibration, potential extreme changes in temperature and air pressure, etc) they may turn out to be too much of a risk for too little reward in weight savings. Adding more cladding and containment and venting systems could easily end up being equal to NiMH technology, weight-wise. If the FAA approves the lithium cells and they end up being the source of another fire, I think they'll ban the technology for quite some time. This is costing Boeing millions with no end in sight. They may go to NiMH just to get back in the air. -- Bobby G. |

You have no facts as to what actually caused the fire, what level of testing had already been performed, what level of confidence they had that the eqpt worked properly, what safety systems were or were not in place, what standard industry practices are, etc. For example if it was one of the first tests on a whole new design, then I would expect a lot of safety precautions in place. On the other hand, if they had already undergone a lot of testing pushing the limits and now they were just expanding the test to different configurations or more lifecycle testing, etc, then I would not expect the same level of safety precautions. We also don't know anything about what else may have failed and contributed to the fire. The FAA person said something that's potentially misleading: "The U.S. Federal Aviation Administration (FAA) on Sunday said it had investigated safety complaints leveled by a former Securaplane employee in 2008 and 2009 but determined that the allegations focused on prototypes that were not ultimately used in the new lightweight airliner."

The batteries themselves have well known problems. During the manufacturing process tiny bits of metal wind up left in the cells. If enough of those manage to line up, the cell can short circuit. And if the cells are large, that can generate a lot of heat, which in turn, causes a thermal run away effect. In this case, from everything I've heard, the NTSB has been unable to find a root cause in either the charging system or the batteries. *YUASA, the battery maker, is also on the hot seat, but to a lesser extent, IMHO. *Charging problems are usually the culprit when a battery assembly like the 787's catches fire, especially if there's no design flaw in the connectors and they can't be easily accidentally shorted. See above. Again, jumping to conclusions. and so Michael Leon's case is getting far more notariety than most. The folks charged with designing a safe battery and charger burned their building down testing their designs. *Should we trust them with a fleet of 787's? *I wouldn't. They did *not"* design the battery. And again, you don't know anything about the particular design involved in the fire and if it had anything to do with the 787's. The NTSB, which is always VERY cautious, apparently doesn't agree with you. But, I don't think they're going to find much more under this rock than notariety. I don't think "notoriety" is the right word. *It means famous for doing something bad. "Dillinger was a notorious criminal." *I don't think Leon qualifies.

If I were on a civil jury hearing his case, I'd tend to side with Leon because that fire demonstrated incompetence. That's why we have $5mil jury awards for nothing. We have idiots like you on a jury. There was a fire, about which you have zero actually facts. Yet you're going to use that to side with a dismissed employee over something that has nothing to do with the fire? Good grief. I'd want to look very carefully at his employment history to see if it supports the claim he was a terrible worker. *Evaluations tend to get doctored up and commendations magically fall out of work history files to make the employee look like the world's worst. *Doctored documents are often a source of victory for the employee because when fraud like that is revealed, it powerfully impeaches the employer.

Wow, you must be an incompetent idiot, like you claim the company involved is. See how easy that was? |

The pilot has a device, called the "Dead Dog Switch", that he flips if there is an animal in the cargo hold. If no animal, the airline saves fuel by not climatizing the area. You can put this information to good use. When the flight attendant asks you if there's anything you need, look up at her with a pained expression and a tear in your eye and say: "This airline froze my dog to death (sniff)." You'll almost always get a free drink. |

Curious why this is on alt.home.repair group and not on the sci.electronics.design or sci.electronics.repair groups. Hermetic sealing can get really important even inside a cabin. Is the fire-prone battery assembly inside the cabin pressurized areas? There are two batteries, both are in eqpt bays underneath, one near the nose, other below the wings. *They are not part of the cabin. Define "part of the cabin".- Hide quoted text - - Show quoted text - I think the usual definition of cabin is the area used for passengers, flight attendants, rest rooms, galleys, etc. The other common definition is inside the pressurized/heated portion of the airframe. *It matters which. The fumes from anything burning in the hold will get into the cabin/cockpit.- Hide quoted text - - Show quoted text - Are you sure about that? Like how do you know that the pressurization systems are common, that the air supplies are shared? The 787 in particular in Boston that had the battery fire, I didn't hear any mention of smoke showing up in the passenger cabin. |

So the areas where the batteries are most likely are pressurized. But it's not clear what the specific issue then is. I would think even if it's pressurized, the air systems would probably be seperate from the passenger sections. Not saying that some smoke would not make it to the passenger part, but it would seem like a really bad idea to have a system where air from the cargo holds gets sent into the rest of the plane. That would make the whole plane susceptible to anything that any of the cargo could accidentally emit. |

That's why we have $5mil jury awards for nothing. We have idiots like you on a jury. This pathetic insult from the guy who believes the McDonald crotchburn case outcome was fair. Boiling hot water can burn you, lady! Keep it off your lap if you've got fumble fingers! Wow, you must be an incompetent idiot Your reply raised some interesting points that I've elided because you CAN'T be dumb enough to believe anyone but an idiot would try to have an adult conversation with an insult-monger like you. When are you going to grow up and start trying to make your points like a man and not a JHS student overdosed on Adderall? We're still waiting. What's most interesting is that you called KRW out for calling YOU an idiot but then use the same tactic on others. At least KRW's not a hypocrite like you, Chet. -- Bobby G. |

Coffee is not even correctly BREWED with boiling hot water, let alone served. The fact is you can't drink boiling hot water without injuring yourself. McDonalds even admitted that their coffee was unfit for consumption at the temperature they served it.

I called you an idiot because you said that if you were on a jury in that wrongful termination case, you'd side with the plaintiff. And you said that with virtually no information about the actual facts about what exactly happened. It isn't even available. That is indeed that type of idiot on a jury that results in completely ridiculous awards. And other than call you an idiot, I took apart your whole pontification, piece by piece. I notice you skipped that part..... You want another example of what makes you an idiot? You come in here with the usual lib lines on guns, how dangerous they are, how we need more gun laws, more bans. Yet, when the truth finally comes out, you have a carry permit. Typical limousine liberal. It's OK for you to carry one, but the rest of us are not to be trusted. |

Virtually always kept above freezing - which at 30,000 ft plus definitely requires heating. Without heat at 30,000 ft it is about 120 degrees colder than ground level |

Without heat at 30,000 ft it is about 120 degrees colder than ground level yet, surprisingly, the 'temperature' of the air molecules is hotter. just not enough of them to keep a person warm. |

Dunno about the 787. But the door would be fire smoke roof. |
