    Product Group: Engines (ME)

    Problem: I have a question on the correct technical data to use to overhaul a 305394-2. The manual being specified on your website is 74-30-01 rev 3 dated Dec 11, 1981. I have this manual but it only gives effective codes for the 305394-2-1, 305394-2-2 and the 305394-2-3. The speed switch I have does not have a second dash number. It is marked 305394-2 J. How can I determine the what the second dash number is?

    Product Group: Wheels & Brakes (WB)

    Problem: Clarification on item 2.6 in temporary Revision 32-2 of CMM 32-43-01 is required
    The item 2.6 in the page 5 of 6 was revised. 
    NDT needs to be performed at every tire change or only when required?
    The tubewell ID will call out a visual inspection at both tire change and overhaul and if any defects are found during this visual inspection, NDT inspection will be required to verify. 
    In other words, NDT inspection is required only when the verification is required. 
    Is our undersntanding correct?

    Product Group: Electric Power System (ME)

    Problem:

    ATA 21 and 36 Questions:
    1) Are BAS and BAM both able to provide data to CDS and who is the prime used by the CDS?
    2) What happen if BAS failed, which Data will be provided then by BAM? 
    3) What is the X-Talk CAN-Bus for in-between EBAS and BOMU? 
    4) If the HP Valve fails OPEN why does the MPV not take over to regulate the pressure until next landing of the AC automatically? 
    5) Will be the TM1 and 2 Data be supplied to both the BAS and BOMU to be used as a backup or will the units provide the data via the above mentioned X-Talk CAN-Bus 
    6) In single Pack operation with both engine bleed systems running and a reverse flow is detected, why does not the X-Bleed close automatic. It must be closed by the flight crew after receiving a caution failure message as far as I know?! 
    7) What is the SIS Connector used for on the front panel of the ASCU and CDM controller? 
    8) If both flow sensors fail in flight or on ground does the pack flow control valve behave always the same (go to full OPEN)? 
    9) Why is the Trim Air PRSOV not controlled from both ASCUs instead of only ASCU 1? 
    10) What is the detailed described reason for the Flow Divider Solenoid to be operated only on ground at specific percentage of APU speed?

    Product Group: Air & Thermal Management Systems (ME)

    Problem: We have a query concerning differences between the 2 dash numbers of Sensor P/N 51090032-00, i.e. -00 vs -01.

    The Airbus AIPC states that  -00 and -01 are not interchangeable. 
     
    Why are the two dash numbers cannot be used interchangeably.
