From the last Egyptian press release (see above)
The analysis of data may take several weeks; if the memory units at both recorders are in good condition; then the unloading process will start right away at the labs of the Central Department for Aircraft Investigation [in Egypt]. Whereas if there is a minor damage at both or either of them; the damage will be repaired locally; but if the damage is major ; then the repair process will be conducted abroad under the supervision of the Investigation Committee.
