Hello,
Takata;


In a reply to Bearfoil you wrote:-
I never read something about that. Reports are saying that all ACARS transmitted by AF447 were received.
I think that Bear is referring to the following detail from page 36 (English version) of the BEA Interim Report No.2. The PRIM 1 and SEC 1 faults below are possibilities, but the MAINTENANCE STATUS ADR2 would have been sent (if possible to do so).

F/CTL PRIM 1 FAULT (2 h 13)
This message indicates that FCPC1 (PRIM 1) has stopped functioning. This shutdown may have been commanded or be the result of a failure. In the absence of an associated fault message, it is not possible to command a shutdown. However, a fault message that had not had sufficient time to be transmitted can not be excluded. Indeed, this message was received at 2 h 13 min 45 and the last message at 2 h 14 min 26, whereas the fault message could have appeared up until 2 h 14 min 45.

F/CTL SEC 1 FAULT (2 h 13)
This message indicates that FCSC1 (SEC 1) has stopped functioning. This shutdown may have been commanded or be the result of a failure. In the absence of an associated fault message, it is not possible to command a shutdown. However, a fault message that had not had sufficient time to be transmitted can not be excluded. Indeed, this message was received at2 h 13 min 51 and the last message at 2 h 14 min 26, whereas the fault message could have appeared up until 2 h 14 min 51.

MAINTENANCE STATUS ADR2 (2 h 14)
This message was received at 2 h 14 min 14 and a class 2 fault message should have been received between 2 h 15 min 00 and 2 h 15 min 14.
