SB 34-2454-02 Static Pressure To Pitot

Hİ dear all sjap user;

A few days ago, they bring me a SB, thats basically check of fucntionally ADM if they calculates and send right information to the all other systems (via ADIRU to TCAS).

In this SB, instructions say that give static pressure at same time to both pitot probe and static ports. (give 1013 MB to pitot and static ports). First i was thinking that it could damage the ADM of pitot probe to give static pressure. Next step, it says supply 460 MB static pressure to pitot probe and static ports.

So we asked Boeing about that, could that damage ADM of pitot probe? Boeing says if i dont give static pressure to pitot probe, i may damage the ADM of pitot probe and read wrong values. So we did it like boeing said.

What do you think about this ? Have you ever supplied static pressure to Pitot Probe and seen any abnormality ? Supply static pressure to pitot probe damage the ADM ???

I don´t see the problem since all the ADM´s are the same P/N.
