Seeing there is continuing discussion on the components located in the area of the THS screw jack, and the apparent ducting, it is timely to note that Flight Global on 2011-04-01 published a new high resolution (4,500px × 2,501px)
cut-away of the A330.
The ducting referred to above appears to carry APU services (including fuel) and may also carry the fuel transfer line to the trim tank in the THS.
I suspect that the detail afforded will help in identifying objects as the are presented by the BEA.
EDIT :: Though of the A300 empennage, the cut-away below shows a similar general arrangement to that found on the A330.
