Awesome pictures, thank you for posting.

Does anyone know what might have caused the leak?

I don't have any official explanation yet. In the previous thread, 320tech provided an interesting explanation of what might be the cause of this incident. I quote him below:

Quoting 320tech (Reply 1):
The fuel is leaking from either the NACA vent or the frangible disc. The NACA vent vents the overflow tank, and the frangible disc is designed to break if the pressure in the tank gets too high. I can't recall which one is located where off hand, they're both on the outboard part of the wing.

If it's from the surge tank, it's likely caused by an error in transferring fuel - although there's no reason why that should happen. The pilot shouldn't really be transferring at that point.

If it's the frangible disc, either the tank overpressurised for some unknown reason - rather unlikely, I think - or else the disc failed.

In either case, the leak would stop after the fuel decreased to a certain level. So it would be possible to fly like that, just not recommended. The frangible disc would be a bigger deal, as every time the airplane banked, it would lose more fuel.

Contrary to what Hollywood would have you believe, most airliners don't have provision to dump fuel. The A320 cannot dump fuel.
Whatever

From the latest Anet pics I know something like "was spotted by fellow memeber...." Does it mean that a spotter brought it to attention to the crew or did I get it wrong?

I guess I'll have to change the comments on the pics as they are a bit confusing. In fact member BA777 of this board was with me that day and when he saw the aircraft coming he pointed out the leak to us spotters but the crew of that airplane found out they were losing fuel by theirselves.

Thank you. I've also done it for the firefighters that are interested. I know there are a lot of discussions about these pictures on several firefighters boards.

Thanks for the info that's what I thought but I wasn't sure.
