The V stab on N14053 sufferd damage thought to be caused by turbulence back in 1988.
An inspection of the V stab uncovered delamination of the composite structure just above the attatchment bolts that hold the V stab to the airframe.
The delamination was repaired using doublers. But no increassed inspections were deamed necessary for the repair beyond the normal schedualed maintenance.

Jetpilot,
What is the source of the new info? Delamination, that is a new theory.

Got this info from a friend who is an AA mechanic at JFK.

The website ' www.aviatonnow.com ' has that delamination information in it's lead article today.

Correct that: it's 'www.aviationnow.com' that has the article with the delamination details included.

I'll say this though: this will guarantee that airlines will do much more serious close inspections of composite structural parts of the plane.
The aging of composite parts has been of some concern to me, since there isn't the long track record of parts aging like you have you metal structural components.

Looks like the info was accurate...for all I know my buddy might have gotten it from a news article....
This isnt an aging of composites issue...if the repair would be at fault then it would be a repair issue.

Hmmm... the entire 380 wing is supposedly going to be made from this stuff...

D L X,
Wrongo. The A380's wing will be mostly metal. I believe the composite structures will be the tail surfaces (vertical tail and horizontal stabilizers).

JET, I know it's good stuff, but repairs will be inevitable. Maybe you can shed some light on this (you fly A300s, right?) but, you can't really repair composites, I thought. You have to replace them, or they'll never be as strong as they were.
Ray, how sure on you about this? I clearly recall reading that it would be a mostly composite, one-piece wing. And that some airlines (and forumites) were complaing about it. Is this a change?

I say the bolts that held the vertical stabilizer to the aircraft were badly corroded and broke off from the heavy turbulence caused by that JAL 747 that took off before it.

If there is a problem with the vertical stabilizer on the A300 which will require worldwide inspections, they will have to include the A310, A330, & A340 which have identical tail sections.

TEDSKI....
This is not a manufacturing defect....but a repair that was made to a damaged V stab....therefore this situation is unique to N14503.

It would seem that if the stablizer suffered damage in 1988 as the orginal post said, it would be known if it was from turbulence and not just thought to be. Also, why did damage occur the first time? Was the turbulence so great that it caused the damage, or was there an orginal manufacturing defect? If it was just due to turbulence, then you must be saying that turbulence encountered the day of the crash was much les than the orginal encounter, and the repair made it not capable of withstanding even this amount, otherwise it would make no difference whether it was repaired or a brand new one was installed.
You said it suffered delamination then, so it may have suffered delamination this time. Jetpilot your statement that it was a repair falt (though well it may be) is just speculation at this point. I don't know the cause yet, and neither do you.

M27...Im just reporting the news as I get it....in no way shape or form did I make any such statement that this was the cause of the accident......
I said it was just something to THINK ABOUT. Read the post slowly next time.
You need to read "all" my posts in order to see the context of my last post.
Anyhow latest word I have is that the V stab broke off above the repair point..... I've got pics of the v stab attatchment points after the crash but dont know how to post them...sorry.

Jetpilot:
I believe I understand what you are saying. That this one aircraft is unique, and if a failure results due to this repair, then of course it would not in anyway relate to any other line no. I will admit that as I read through the posts, that I lost some perspective to whom, and to what you were replying to exactly, and for that I apologize.
I will take the statement that you made that tails aren't
falling off unrepaired A300s' as a general statement and not that you meant it to mean that the repair must be the reason beyond doubt that this tragic event happened. As I said, it may well be a repair falt, but I believe that can't be said for sure at this time, and that is what I thought you were promoting.
