Emirates berates Airbus over superjumbo cracks

in the hard copy newspaper, "made of 7449 aluminum, that is lighter than other types" that is nonsense. all aluminum based alloy metals weigh very close to the same. they are majority aluminum, and would have no more than 10% or so of additions.

another comment, ,,,...there are 4000 web feet on a 380, and typically finding 20 to 25 of these brackets have cracks. i think that is between each engine on each wing.

there is talk about grounding the 380's

i am unable to find the full article on the web.

It will be interesting to see how well the 787 fares after some serious cycles.

Both the 380 and 787 are lovely planes, but both are very different animals from their forebearers.

got a schematic of the wing rib and the feet. if they have to add a pound a piece to those feet, that's 4000lbs which i think will start getting into the payload. less than 2cm for those who do not think metric is more than 1 inch, less than 2.

in metallurgical terms, those cracks are like this is "a little bit pregnant". cracks propagate, not terminate.

doing the numbers, i would not get on one of these babies till they finished the fix.

2cm is 0.787 inches. So they are 3/4 of an inch or smaller.

You need to talk to someone who knows how this would be fixed, because your post is full of errors.

There is NO WAY that it would require an additional pound of material to repair one of these parts. The rib foot might weigh a few ounces, even if you doubled that weight you are talking about a few ounces, probably much less.

You are also incorrect on cracks. They can terminate themselves, either at the edge of a part, a lightening hole or at a fastener hole. Airplanes are designed to have damage such as this and for inspections for this type of issue to happen at regular maintenance intervals.

Every airplane you have ever flown on has cracks, corrosion and defects. This airplane model is no different.

What numbers are you "doing," exactly? If you do the numbers on auto accidents, do you conclude that it's safe to drive to the airport?

no, but it is necessary to drive to the airport. i think it is much less safe to drive to the airport than to fly to europe. i would take public transport which i think is safer than personal vehicle, but driving is a necessity. i do drive in what i think to be one of the safer vehicles. i have a toyota sequoia (about 5000lbs)with all the air bags possibly available.

i have not seen any crash tests of sequoia vs say a MB. only mb vs a fixed wall.

Most aerospace Al alloys have about 3% copper in don't they - and are precipitation hardened?
