The Technical Investigation Committee of the A320 accident had primarily studied FDR data as well as performing time correlation between FDR and CVR data.
The committee had also unloaded CVR and started listening to the cockpit voice recordings before the occurrence of the accident; where the existence of a "fire" was mentioned. Still it is too early to determine the reason or the place where that fire occurred.
Additional work on the CVR, the FDR and the recovered debris is continuing.
