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. Wayne 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. |

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... Denny "Sydney Hoeltzli" wrote in message ...

Tsk, tsk, Sydney... Bad hair day?

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. This is good to know -- thanks! 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. 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. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" A fabric pocket should actually be a good place, provided the fabric meets standard aircraft flammability tests. Cheers, Sydney 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. |

I am buying our fourth ANR headset at OSH 2003 later this month. It
most certainly will NOT be Lightspeed brand. I guess I'm willing to give them another chance, because I just haven't found anything out there which is as comfortable and quiet with a better reputation. Well, brand loyalty only goes so far. Another example: I was firmly, 100% behind Lowrance, and we LOVED our Airmap 300 -- until it started to flake out on us last month. Still, I was with them, and we were really excited to hear about the new Airmap 500. I wanted to see it at OSH in the worst way! That is, until I discovered that -- after just four years(!) -- Lowrance is no longer supporting my 300. Repairs for my flaky little GPS were simply no longer available. Poof, that was the end of MY enthusiasm and brand loyalty. Garmin still supports every GPS they've ever made, and THAT says more about a company than data sheets or marketing ploys, any day. Thus, soon a Garmin 196 will be resting comfortably on my yoke, God willin' and the crick don't rise... And some OTHER brand of ANRs will be setting upon my balding pate... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Assuming the problems reported are legit, this seems to indicate a quality
assurance issue with the manufacturer. I was just looking over the Lightspeed web site and didn't see any indication that their headsets were TSO'd. Now I will be the first to admit I'm a newby so I my impressions may be in error and as such take anything I say with a grain of salt but my understanding of what TSO means is that 1: the product was type accepted, passed testing to insure that it did what it was supposed to and was compatible with and did not interact negatively with the other aircraft systems, and 2: that the manufacturer has quality assurance programs in effect that would insure all products coming off the line met the same performance standards as the samples submitted for approval. I may be wrong, but it seems to me to be foolish to buy non-TSO'ed equipment for permanent aircraft installation or for use by the PIC or FO if there is one. If my understanding of the QA issues regarding TSO is correct, this would certainly increase the price of the product because testing of each and every unit coming off the line is certainly going to be more expensive than testing randomly selected samples. Because of the unforgiving nature of aviation, uncertainty of product quality where safety of flight is concerned is something I personally can't afford at any price and battery packs that spontaneously burst into flame certainly seem to me to be a safety issue, even if they're carried enclosed in fire resistant pouches. "Dennis O'Connor" wrote in message ... 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... Denny "Justin Case" wrote in message ... Lightspeed seems to know everything about all of their problems and they all seem infrequent. Just too many infrequent problems for me. |

Well, I just checked out the Bose, Sennheiser, and David Clark web sites, and it seems that none of their ANR headsets are TSO'd either.

"Steve House"
shared these priceless pearls of wisdom: Now I will be the first to admit I'm a newby so I my impressions may -be in error and as such take anything I say with a grain of salt OK, that's a good start. but my -understanding of what TSO means is that 1: the product was type accepted, Nope. It means the manufacturer tested the unit in accordance with the Technical Service Order and it met some arbitrary specification. Look up the TSO for audio panels some day. There are still vestiges of vacuum tube terminology. -passed testing to insure that it did what it was supposed to and was -compatible with and did not interact negatively with the other aircraft -systems, Nope. That's the installer/approver's job. and 2: that the manufacturer has quality assurance programs in -effect that would insure all products coming off the line met the same -performance standards as the samples submitted for approval. Nope. That's PMA. I may be -wrong, but it seems to me to be foolish to buy non-TSO'ed equipment for -permanent aircraft installation or for use by the PIC or FO if there is one. And how many airplanes did you say you have owned or paid the maintenance bill on? -If my understanding of the QA issues regarding TSO is correct, this would -certainly increase the price of the product because testing of each and -every unit coming off the line is certainly going to be more expensive than -testing randomly selected samples. Even if the FAA approved testing procedure calls for random sampling? Not hardly. Because of the unforgiving nature of -aviation, uncertainty of product quality where safety of flight is concerned -is something I personally can't afford at any price and battery packs that -spontaneously burst into flame certainly seem to me to be a safety issue, -even if they're carried enclosed in fire resistant pouches. Did anybody say anything about bursting into flame? Sydney said the damn thing got hot to the point of softening the plastic case. Don't build hysteria with wild-ass projections. And, if you are so worried about product quality, then build 'em yourself. That way you have 100% control over the product and performance. www.rstengineering.com {;-) Jim Jim Weir (A&P/IA, CFI, & other good alphabet soup) VP Eng RST Pres. Cyberchapter EAA Tech.
