One wonders if they are anything like the cracks QF discovered in one of the ex Malaysian 744's they bought a while back. Huge crack started from scribe marks from scraping paint or sealant with the wrong tools!
Of course QF don't have the spare capacity for cutomer repairs like they once had so it might be there a long time!

So will structural problems such as these show up as easily on the new plastic fantastic 787? After all most of the 747 fuselage is a long way above a pilot on walk round.
I realise that plastic doesn't corrode, but what warning signs does it give that a potential problem is building up? I presume the static test airframe will show this info given time.

The question I have is were any cracks actually found? I had heard a rumour that it was damaged by some ground equipment, and was therefore more of a gash than a crack. Be interested to know the truth.........

Direct experience of Thai Engineering over many years has indicated that they are professional, competent and thorough. I would be surprised (to say the list) if this was a result of undiscovered - or ignored - corrosion.

I think you will find that the dodgy paint stripping resulting in scoring at the lap joints and subsequent cracking was not done by MAS themselves. The same problem appeared in ex MAS B737's that went to Ryanair.
The painting contractor was using box cutters during the paint/sealant removal.

I flew back from Hong Kong on a Thai 747-400 last week and looking over the wings and engine housing, the paint-job was horribly bubbled.
Does this have much of an effect at speed? It certainly can't help the drag. That said, you'd have to applaud the cohesion (as opposed to the adhesion) as the bubbles had not been ripped off.
