Lightspeed Battery Box Warning

LS owners seem to fall into two groups... Those who have never had any
problem over a number of years of continuous use, and those who seem to
lurch from crises to crises... Strange...

Lightspeed seems to know everything about all of their problems and
they all seem infrequent. Just too many infrequent problems for me.

Well, I guess I must be the exception which "proves" your rule, since
in general we have been very pleased with our Lightspeeds and while
we have had a previous problem with my 20Ks, I certainly wouldn't
describe it as a 'crisis'. Nor would I personally describe 2 problems
in 5 yrs ownership of 3 different headsets as "lurching from crisis
to crisis".

What seems strange to me is your perception, actually, but that
wouldn't be the first time.

Cheers,
Sydney

wouldn't be the first time.

I believe Denny is perceiving this:

The only reason many Lightspeed owners have NOT had repeated problems with
broken wires at the plug is because they specifically lay the battery box on
the floor, or tuck it in a side pocket. This removes the weight of the
battery box from the inadequately designed wire and plug assembly, and keeps
the wires from breaking.

NOW it has come to light that laying the battery box on the floor (or
tucking it in a pocket) can result in a conflagration of your aircraft.

This is, indeed, a "crisis" of quality control, in my opinion. And, as I
have repeatedly stated in the past, is truly a shame, as we absolutely,
positively LOVE our Lightspeed headsets.

Actually I think that's overstating the possible outcomes considerably.

What happens is this. The battery box shorts. The batteries get hot.
The battery box gets hot. The battery box begins to melt. The
batteries lose contact w/ the deformed battery box, the short circuit
is broken, and the heating stops.

The worst case is if the battery box happens to get hot enough to
melt low-temperature plastic trim, which can be expensive and costly
to replace.

The fabrics used in the interior of the aircraft had durned well better
withstand a much higher temperature without igniting, or someone
installed the wrong stuff. Likewise, it should not get hot enough to
ignite paper.

I discussed this in detail with the Lightspeed engineer. DH, who has
extensive training in fire hazard prevention, concurs. Of course, there
can always be some combination of factors which lead to a different
result.

So I wouldn't worry that your Lightspeed battery box is likely to
cause conflagration of your aircraft.

However, I would make sure you don't place it somewhere which might
melt and cost you time and $$. For example, we've been securing our
20K and 25XL battery boxes with velcro (sewn to the plane interior,
glued to the battery box). This is gonna stop, because velcro melts
at rather low temperature and melted velcro would trash my interior
panels.

A fabric pocket should actually be a good place, provided the fabric
meets standard aircraft flammability tests.

In my old boyscout days we used steel wool and a 6 volt lantern battery
with some of the most flamable papers and grasses etc to attempt to start a
fire. It took forever and many never got them to ignite. I agree that what
happened to you was not a fire hazard. You'd have a better chance to win the
lottery than to have that ignite on it's own, or maybe getting struck by
lightning, twice.

Ummm, I see my name mentioned, which tends to wake me up... Then I see a
quote of my analogy of 'lurching from crises to crises'... This brings me
to the fully cognizant condition (rare) so I look at my post on that
topic... Hmmm, verb and subject are not clear - my fault...
For those who may have garnered the idea that I was back handedly, character
assassinating Sydney, et al., as being somehow at fault for their LS
headsets failing, that is wrong... LS needs to improve their product -
especially where the battery box melts down - jeez!

Anyway, I was simply noting that we see posts from the one group who
seemingly never have a problem with their LS headsets, and posts from the
other group who's LS headsets seem to be jinxed - with little or no middle
ground, i.e. no bell curve.. As I said; strange...

This is good to know -- thanks!

I've spent over $1000 with LightSpeed, and I sure don't expect their
headsets to melt down in my airplane.

Of course, I didn't expect to return all three pair for multiple repairs,
either.

I am buying our fourth ANR headset at OSH 2003 later this month. It most
certainly will NOT be Lightspeed brand.

Sydney,

ah, a voice of reason. Thanks!

That can't be true in my case, at least. My battery box is plugged
into the middle of the panel (left of the turn coordinator) and the
battery box hangs down from there. The box's weight causes the cord
to bend 90 degrees right after it comes out of the plug. That has got
to be about as high stress as you can get on the cord. Why I have had
no problems is a mystery to me. The only thing I can thing of is that
I leave the headset in the plane most of the time rather than plugging
it in and removing it again. That probably reduces the strain on the
cord.

Sydney,

First off, thanks for the post. I would be interested in knowing what
actually shorted out (sounds like a spring contact or some such, most
likely, in the battery box).

You are right that, compared to having, oh say, a wing spar break, it's
hardly a "crisis." OTOH, I've got two Peltor's and a Dave Clark ANR -
average life 10 years - and never had a problem (other that physically
wearing out the earpads) with any of them. So you can see that, relative
to the "crowd," you are well to one side of the curve.

[Not that we wouldn't expect you to stand out in a crowd regardless. G]
