If I read it correctly it suggests the fire was not the cause of cutting the FDR recording. Which sounds a bit far fetched at this stage. Would surprise me if you could read that from a CVR.
Going over to emergency power and thereby losing recorders might be a factor. But if there was a fire who could determine that it had stopped. In the SR111 case it took the pilots more than 10 minutes to find out that there was a fire.
Would be interesting to have the CVR information they suggest they have.
