A major advance in repairing composite components bodes well for commercial aircraft that contain composites in large proportions of their structures, such as the Boeing 787 Dreamliner, shown in South Carolina as the first one built there is rolled out. (Source: Boeing)
I think the other differences in car vs airplane accidents are key: cars have (usually) 1-2 people, not tens of people; cars are on the ground, not in the sky, so damage is likely to be greater in a plane crash; cars are driven by private citizens, not company employees; car passengers are more like to travel for "free" vs the ticket price for the privilege of flying in a commercial aircraft with no legroom, absurdly low baggage allowances and crummy food. All of those factors raise our expectations, and I think rightfully so, for the safety of air travel over car travel.
That's pretty normal in the industry. And it; s being done by certified by low cost shops. You definitely won't see robotics anytime soon in say Belize. That's a different thing, that's air traffic and ground control. That is all due to human error or just over crowding unless the brakes went and it rolled out in front. As bad as these sound when was the last major crash? And compare that to driving, then you start to see how safe it is. The problem is no one reports a fender bender even in a bus. Take those same people put them in an airplane bump into a building or ground vehicle and its coast to coast news. It just doesn't happen that much so when anything does it gets way over blown as to its importance. So now we know airplanes , cars, bikes, trains an ad walking are no good guess we are stuck annoying everyone else over the internet :-)
KingDWS, I haven't flown a lot in the last few years but before that I didn't see anything as scary as what you describe. OTOH, I have wondered about the apparent decline in maintenance quality in the last decade or so, which became evident after several high-profile near-misses in the air and on the tarmac.
Unfortunately for your flying piece of mind I am referring to Boeing and practices. You have to keep in mind that the airframes keep getting passed down to smaller and smaller operators with smaller operation and maintenance setups. Eventually they just no longer become viable and get junked if they have no cargo capabilities or face noise or excessive fuel burdens. There are still 727's flying cargo and those had to be one of the worst for noise and fuel burn but they are fast and there are cargo door kits still available. The thing you have to keep in mind is if you see tape holding anything together fake a heart attack and get off :-)
KingDWS, since Boeing et al are the big commercial plane makers, it seems that your comments about repair don't refer to them. So what class of planes are you talking about? They don't sound like aircraft most of us are likely to fly on. Is that correct?
The normal work being done are the major checks which are very labor intensive or repairs such as corrosion that require a lot of labor as well. These type of operation usually require the airplane to be almost stripped bare during the repair. The day checks are normally done at the airlines maintenance facility or regional facility these are fairly minor compared to other inspections or repairs. These shops and repairs still need to be done according to the book so they are licensed and the materials are the proper ones. The ones I would worry about are from peru columbia a few other places those are not exactly reputable repairs (I'd rather walk :-) )
Unfortunately the whole industry is very cost driven so this is going to become more common.
In theory the shops and people or someone has to have the same certifications as up here. You only need one person with the right tickets to sign things off and that's legal. This has been going on more and mores since about the 80"s and perhaps longer that's when I started. Put it to you this way, have you ever flown south on what seemed like a old rattly hunk of junk and then a week later fly north on a nice fresh one. Most of these shops do the very expensive major checks and inspections, the fuel cost is actually not much of a factor to get them down there even when flown empty. Like I said the robots are cool but cheap labor rules.
Interesting, KingDWS. I didn't realize aviation repairs were getting outsourced to low-cost labor markets. Do these low-cost sites have to produce skilled technicians. Are there regulations governing the quality of these repairs?
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
