Hi,

I just wondered if anybody can give us an update on how the modifications are going on the Dreamliner.

Also, what testing is still required prior to first flight and has any more testing been done whilst modifications are being carried out?

I'm sorry if this has been posted elsewhere recently but I did a search and there were no topics with similar wording.

Regards,

A380Heavy

ZA997 and ZA001 are currently having the modification installed. Completion is planned for next month, as I recall. Then testing will resume on ZA997 and if successful, ZA001 will make first flight.

Just read in Flightblogger that 787 and 747 could have their first flights very close in time (I would not call it the same day... that would be too much of a coincidence):

787, 747-8 could fly on the same day

Boeing screwed up the temporary hangar they have built on the PAE flightline, it is not big enough to house a 787 AND allow the work for the wingbox mods.

ATS (nee Goodrich) currently have a 787 in their hangar as Boeing has run out of room.

That could mean many things.
Decoupling the test programs like boeing said may very well mean that they fully expect that the 787 and 748 will have differing levels of succesrate in their test phases.

The ,still very vague ,dates they set concerning first flight , now the decoupling of the programs could very well mean that they think the 787 test won't be as easy and quick as originally planned and isn't expected to keep pace with its more mature big brother during the testing program.


Worst case scenario ,I know ,but not out of the realms of possibilities I believe.

Or it could just be that the 747-8, as a derivative, requires a different and less onerous flight test and certification than a "completely new" model.

And separating the flight test teams and ensuring each has the resources they need will ensure that neither program ends up impacting the other. Boeing needs to get 747-8Fs into customer's hands while they're still willing to take them, even in the face of a significant collapse in cargo lift needs. They also need those delivery revenues coming in to start paying down multiple billions they've spent developing and producing the birds.

So now is not the time to be "penny wise and pound foolish" by holding up the 747-8 program if the 787 program encounters new issues due to trying to use a single test pool for both programs.

Makes perfect sense, let's hope I'm reading too much into things and you are right.

There's a new post on Randy's Journal to say installation is underway. Not much information though - mostly fluff. I'm not at work today so I can't say what was in Jim Albaugh's message which Randy refers to, but it's probably the usual pep talk.

In that case the wingbox mods must be handled differently than published before.. What has changed that the temporary hangar suddenly is too small?

I don't know that it was ever intended to do the work.
The composites - when not painted don't do well in UV.
Might want to find out what SN is in the shed and if it is painted.

My understanding is Boeing contracted 2 bays from ATS.

It's ZA002 in the tent - the one painted in ANA colours.

The WSJ and SeaPI indicated that work started this week.

What leads you to that (false) assumption? Looking at Randy's posts, it's pretty clear that the plan was to use the temporary hangar for mods. Why would you need more room to do work that takes place inside the airplane?



That's why we're here.

Surely, unless you were taking the aircraft apart to carry out the mods, you wouldn't need more space than the plane fits into, plus a few feet of clearance all round. There's plenty of space fore and aft of the wing to bring in anything you might need.

http://www.flightglobal.com/articles...begins-787-wing-modifications.html

Announced that modification has begun on static test and ZA001. Should take 30 working days to complete. Then, static testing to be done to check that static margins are where they should be, then complete wash, short "warm-up" gauntlet and taxi, and then... First flight!

(I started a new thread about that article)
