This was mentioned early on the investigation... I wonder if there are any details on what the discrepancies might be?

That could mean maintenance not performed by the book, but also could be something even more serious, americans had never been excited about.

an object without any active buoyancy control will either float or sink. It will not remain suspended mid depth. In fact the feedback that does apply (compression) further promotes this behaviour. However ! a heavy object with only a fraction percent buoyancy . when subjected to heavy swell will spend most of its time completely submerged ! This because when submerged there is only a small force bringing it back to the surface, but once it breaks surface large forces accelerate it downwards again.

They are reported to be waiting for the end of the holiday period when they might be able to get data from a Spanish sub-contractor that supplied a numbered component within the flaperon. If this sub-contractor has data on the history of this component then they might be able to tie the flaperon back to MH370.
I reasoned this because:
1. Assuming EADS-CASA does not know which flaperon is going on which 777,
2. And if EADS-CASA knows that the "part number" was produced after 9M-MRO was assembled(built),
3. And if the flaperon on 9M-MRO was never replaced(Malyasian Airlines should know),
4. And Boeing has no record of the "part number",
Then the flaperon found on Réunion could not have come from 9M-MRO.
The one caveat:
The above 1, 3, and 4 are true; 2 is false and;
5. EADS-CASA uses the "part number" to find additional information that it provides Boeing. Then Boeing uses this additional information combined with their own information to confirm the flaperon was put on 9M-MRO when it was assembled(built.)
If the above makes no sense to you, please disregard it.

If they could use the "numbered component" to tie the flaperon to a specific batch or delivery date from CASA to Boeing, that could be sufficient to determine whether the flaperon belonged to MH370 or not.

I think we're over-complicating things here.
If an individually serialised component has been found, it's almost certain that EADS-CASA will be able to tie that to a complete flaperon assembly's serial number from its build records.
Boeing, in turn, will know which aircraft that flaperon was fitted to on the line at Everett; if it was to a Malaysian aircraft, the airline will know if was ever removed/replaced in service.
It's not rocket science.

I live in a coastal area and see neglected mooring buoys sink then float. The weight of barnacles and mussels eventually causes the buoy to sink. Then after a few months some of the barnacles and mussels drop off and the buoy surfaces again. Then the cycle starts again. Maybe better nutrients near the surface causes the barnacles and mussels to grow again and then it sinks again.

It is only a location number of an access panel.The number is the same on each B777.

If you refer to the printed number "657BB" it is not a serialised component.
But I am quite sure that EADS-CASA identifies much more parts by individual numbers, not necessarily specific serial numbers, but at least batch numbers or modification status numbers, which could narrow down the possibilities where the flaperon belongs to significantly. The production QS will most probably use some sort of barcode-stickers or something like that to track the components that were produced, inspected (e.g. ultrasonic for delaminations) and then finally assembled to form a flaperon. It sounds like at least they do expect some "numbered component within the flaperon" to identify it further.
In light aircraft production it is standard to embed small serial number stickers within the translucent GFRP laminate, visible from the outside but not removeable. In CFRP this is a different story, but even those have GFRP layers in the contact area with metal fittings which would allow for permanent part identification stickers.

Indian Ocean garbage patch https://en.wikipedia.org/wiki/Indian..._garbage_patch
There's loads of information about debris in oceans. Some of it goes down in a vortex, swirls around for months and then pops up somewhere else being trapped and carried in a gyre. The behaviour of a component of roughly neutral buoyancy doesn't (necessarily) follow normal linear behaviour.

Direct Part Marking for Unique Identification with Machine Readable Information
The above is the current Boeing ID method, similar to the internet QR Code, but whether it applied to 9M-MRO, I do not know.

Various forms of 2D bar codes have been around for a long time. Some of my colleagues worked with RR on automated scanning of 2D dot pattern codes for identification of individual turbine blades about 20 years ago.

Are you adding anything to what I wrote?
There are several brackets bolted on that can be disassembled and exchanged for a "spare part".
(Deleted the rest since similar comments have been made earlier on this thread)

Well, if you want to teach the readers of this forum "correct French", that's fine with me. I thought it was more relevant that the investigators are looking at detachable parts that have a number on it. In this context that means a serial number. They don't need the part number. If they want to order a spare part, they can find the part number in the Boeing Illustrated Parts Catalog.

The Kiel lab used a model of ocean currents to guess its drift path.
French investigators strongly assume it comes from the lost jet.
French investigators strongly assume it comes from the lost jet.
1.. There are many places in the Indian Ocean where the flaperon "could" have originated from and arrived at La Reunion.
2.. No. The French investigators are questioning what they have so far found, i.e. the expected Serial No. plate is missing, and repairs/mods supposedly by made by MAS don't match what they see.
Finally, what particular point are Geomar trying to make? Can they gain support from the INMARSAT data for their claim, or are they just trying to debunk any other theory?
