Just been revisiting the report into PA103 over Lockerbie. Interesting reading in terms of effects and break up sequences. The following is very similar:
CVR
It was possible to establish that a loud sound was heard on the CVR cockpit area microphone channel at (19:01:50) +/- 1 second. The tape record ended, at (19:02:50) +/- 1 second, with a sudden loud sound followed almost immediately by the cessation of the recording.
FDR
Decoding and reduction of the data from the accident flight showed that no abnormal behaviour of the data sensors had been recorded and that the recorder had simply stopped at (19:02:51) +/- 1 second
