Looking at the photo of the CFM56-5 Gearbox in post #728, given the rather high rate of descent during the pod strike - the gearbox casing almost certainly would have fractured (it's cast so relatively brittle). Best case, they would have lost nearly all the engine oil almost instantaneously. It apparently didn't do catastrophic damage to the gearbox internals since they would have lost the fuel pump and the engine(s) would have quit in a few seconds.
Speaking about acoustic warnings, and considering there were so many parameters out of limits, they may have gotten "SINK RATE , SINK RATE" , and "PULL UP, PULL UP" before the runway impact. Besides, there´s the ECAM , which surely was active with ¨"LANDING GEAR NOT DOWN" in red capitals and the MASTER WARNING caution flashing red and the chime sounding, But TUNNEL VISION is very powerful and blinding when the pilot flying is just trying to get the bird on the runway.
Anyway, my guess is that it won´t be long before CVR and FDR readings will be made available and it will be clear which warnings and in what order the pilot completely disregarded.
