Some of the best leaks comes from Embassies. Also I am trying to imagine the delicate balance BEA would need to hold in case an airline (not AF obviously) put the reputation of Airbus at stake -like the "XX Air Airbus crash" where XX Air did every possible (or almost) mistake leading to an avoidable crash.

Plus a very sad death on the ground, which I had missed. Apologies if this is a repost.

Airbus communicated the following to all operators last night:
”Based on the preliminary analysis of the available data (accident site information, ATC records, FDR and CVR data), Airbus has no specific safety recommendations to raise at this stage of the investigation.“

This statement says a lot. It means there wasn't any technical problem.

Exact. No it is up to the local investigators, to find out what the incentive for the crew was, to land that plane above the tire rating of 195kn on a nice calm day with an empty airspace around them.

Known at this time.

Still to be reported is why certain pilot actions were taken.

At this time there is no clear corrective action and "it ain't over til its over" (Yogi Berra)i

'Both recorders provided valuable information for the investigation.'

Interesting point. Bridgestone provides a uniform tire rating for A300 up to A321neo at 225mph ~ 195.5kn: https://www.bridgestone.com/products...plications.pdf
Is there any additional warning going off specifically if you attempt to land at a higher speed in the Airbus? Notwithstanding that in this case they circumvented application of the landing gear.

no. It’s a basic committed to memory limitation. Every rated airbus pilot should know the dozens of limitations cold.. Pro pilot 101

Probably designed to cope with a FLAP UP/ ZERO landing at max landing mass....?

Sure. Still there might be a difference between thinking "Well, I am not really supposed to go in at above 210 knots" (rote memorizing) and "I know that if going in at above 210 knots I may likely toast my rubbers" (deductive reasoning based on physics). It could be important to the thought process of the pilots if they were thinking, okay, well being too fast we might have done a job on the tyres at the first attempt, but surely the donks are going to be fine still.

A normal fit person who has had a (usually copious) meal at, let's say 22;00 and six hours of good sleep will NOT be hypoglycemic when they wake up. Their blood glucose should be towards the low end of normal and will actually rise somewhat as they get busy. The body has plenty of glycogen reserves in the liver and muscles. If they continue to fast they may get thirsty after a few hours, but that'll do them no harm. I reckon that it would be at least 36 hrs before their blood glucose started to fall to such degree that they cannot fly a modern aircraft safely. They'd certainly be hungry.

I certainly done gigs like that and never felt faint, though you can't keep sharp indefinitely!

In an open boat, three days without any water, three weeks without any food is about the human limit

So I don't take that Ramadan stuff seriously, unless they were complete wimps.

hot and high slat/flap fail landings and engine failure at v1 based on my last outings in the Sim!

This is an exemplary demonstration of how to do it right.
The BEA report simply notes that there are no technical issues that need to be addressed. Any implications are left to the reader.

So basically there wasn’t anything out of the ordinary , and we are still back to square one.I am honestly surprised if there won’t be a maintenance issue.

Pray tell us which systems(s) malfunction(s) due to improper maintenance could have caused the crash.

Airbus were very quick to say "Nothing to do with us" in this case.

And in the end, the truth was somewhat different. BEA, I'll take a listen to. AB? Maybe with a grain of salt.

That said, if I were to bet a notional 100 dollars in Las Vegas, I'd not be betting on "it was broken" as a first roll of the dice.
