It's not part of the normal procedure. Rework is scheduled to continue until the end of the year. That does not sound that great, that would mean frames upto what MSN 90 - 95 would still be effected by rework ?

We are at MSN43 and there's no sign of this ending. I'm beginning to wonder if this 'rework' is actually a part of the normal production sequence and that those tents are 'temporary' in that they will find a dedicated building for this part of the production later. I still think rework is the wrong word. I guess it is work not yet integrated in the preFAL and FAL stations.

I believe Boeing called similar work in the B787 program as "traveling work".

I'm beginning to wonder if this 'rework' is actually a part of the normal production sequence Recently produced frames only spent a few days in rework. I think this will soon come to an end. Let's however remember that there is almost always something to fix on any airplane after roll-out.

Recently produced frames only spent a few days in rework. I think this will soon come to an end. This little piece of information could actually go well with what sciing, addasih and I have been on about. It is not a 'fix' but part of the work that should be done within the FAL process. But due to the learning curve in the beginning, this could not be done during the FAL and so has to be completed outside, i.e. traveled work. As they move along the learning curve, the time taken to complete the job is reduced to the point that it can finally be done within FAL and not require the tents.

Up to that - new knowledge and improvements are coming all the time - look at the development of A330 so I do not believe the rework phase would ever vanish. There might be periods when it is smaller and it might be later bigger etc. The A330 from the period of MSN 200 is dramatically different to the one with MSN around 500 and even more around 1000 and much more around now.......

Well looking at the production list. Seeing that MSN 39 and 41 are now in paint (MSN 41 already done) that would indicate that MSN42 and MSN43 would be due to go to paint within the next 2 weeks. If that holds true then It would mean we are down to 5 weeks of rework.
MSN 42 is at the parking stand so I assume its waiting to go to paint. (A little bit of a delay with lack of capacity to paint).
Also seems like the station 20 are filled up (8 stations in total?) So we have 1-2 frames usually waiting to go into Station 20.

This is an entirely different topic. - Rework on early frames is a consequence of early improvements following flight test findings. - 'Traveled work' - per Boeing parlance - is a consequence of an increasing assembly pace : aircraft are moved on to the next station even when some items are still missing. - Design improvements can be implemented even on mature aircraft to keep them competitive (for instance, Boeing now sells an improved 77W, hoping to spur enough sales to keep the line going at the same pace until 777X production starts). Production however is performed per plans. I agree with Baroque, most probably the tents now are used to perform work that was left out for lack of time in the assembly process. Strictly speaking, it's no 'traveled work' since everything in this case takes place in the same factory (work does not 'travel'), whereas Boeing coined the term when they had unfinished fuselage sections shipped to the FAL and completed there.

I still do believe that even the venerable A330 goes into some amount of rework since as the improvements are coming they are not in sync with the production of parts prior to assembly.... And of course as Baroque says the "traveled work" of course goes on - and to distinguish which is which might be for us impossible.
I do not believe there is ever WB plane without some rework.
I believe there might be some NB which happen to be without it - since there is much faster turnaround.....
