I wouldn't be surprised the recorders are stuffed eg Jeju; possibly the rear one "died" on the power interrupt and the front one got smashed up in the crash
Always possible, however since a pilot made a radio call there was some emergency leve l power available, which suggests the EAFR would be powered.

The Jeju recorders were okay if I recall correctly, they just had no input, was that the case?

Somoeone made a good point above about the German Wings FDR/CVR being available the next day after the aircraft was aimed at the ground like a missile. These things are built tough, as you know, this may be type specific but….

  • Fire (High Intensity) - 1100\xb0C flame covering 100% of recorder for 30 minutes. (60 minutes if ED56 test protocol is used)
  • Fire (Low Intensity) - 260\xb0C Oven test for 10 hours
  • Impact Shock - 3,400 Gs for 6.5 ms
  • Static Crush - 5,000 pounds for 5 minutes on each axis
  • Fluid Immersion - Immersion in aircraft fluids (fuel, oil etc.) for 24 hours
  • Water Immersion - Immersion in sea water for 30 days
  • Penetration Resistance - 500 lb. Dropped from 10 ft. with a \xbc-inch-diameter contact point
  • Hydrostatic Pressure - Pressure equivalent to depth of 20,000 ft.

having a brand new FDR lab, might not be sufficient in case you have to reconstruct the melted data access paths to the core memory modules
Well if a brand new, completed in April purpose built facility is not up to the task, then what hope is there. That is why it was built, for just this eventuality. Knowing a little about things, I would venture that know how is more critical here than the equipment available.

Either way, the US facility is avaible, so why take a week to decide to send it there?

Here is their reasons…

The ministry said the AAIB will determine the location for analysis after a "due assessment of technical, safety, and security factors".
​​​​​​​Some interesting words in there. Yes Minister.
