Purpose The present article identifies all the known CFDS anomalies and BITE deviations. It is intended to be used by maintenance engineering as a synthetic document, providing a short description of each deviation, as well as the affected part and the helpful information, with a cross-reference to relevant additional documentation procedures. The failure/warning messages and behaviors that should be known by line maintenance teams are covered by the TSM. All CMC and CFDS filter envelope content are described in the ISI 45.00.00039.

1. Purpose The present article identifies all the known CFDS anomalies and BITE deviations. It is intended to be used by maintenance engineering as a synthetic document, providing a short description of each deviation, as well as the affected part and the helpful information, with a cross-reference to relevant additional documentation procedures. The failure/warning messages and behaviors that should be known by line maintenance teams are covered by the TSM. The condition of occurrence of the messages and behaviours described herein is accurate, known and reproducible. It also includes intermittent occurrences for which a statistical survey revealed more than 1 every 5 flights per aircraft without any logbook complaint.

This revision introduces updated data. Changes are highlighted by a vertical revision bar in the left of the respective page. New and Revised items in the attached ISI00.00.00228_ .pdf file parts A, B, C and D are highlighted by a vertical adjacent “NEW” and ”R” in the page margin. 2. Description This part of the article describes the attachments of the present ISI. Airbus has updated the CFDS BITE anomalies according to below layout. The attached ISI-00.00.00228_ .pdf file is divided into four parts which are: A. The list of failure messages (internal and external) which request specific maintenance action. B. The list of ECAM WARNINGS and MAINTENANCE STATUS, which request specific maintenance action. C. The list of CLASS 3 failure messages which request specific maintenance action. D. The anomalies related to the general use of the CFDS. Note 1: The classification criteria of data recorded in parts A, B, C, D of this document is the ATA chapter associated to the message/anomaly. Each page of parts A, B, C and D indicates: 1. The ATA chapter of the message or anomaly. 2. The description of the message which is considered as non-justified under some conditions. 3. Airbus recommendations. 4. The LRU affected by the anomaly. 5. The P/N of the affected LRU. 6. The LRU corrective P/N. 7. The reference of additional documentation to obtain more details about the anomaly. Note 2: New/revised items are highlighted by a vertical adjacent “NEW” or “R” in the margin. Note 3: Lower-case letters such as “i” or ”j” represent a variable integer (usually 1, 2, or 1 to 3). “i” and “j” are used in the messages. “X” represents any alphanumeric character in the P/N Note 4: For each item, check carefully that the P/N fitted on your aircraft corresponds to the affected P/N mentioned in the ISI. Otherwise, the remark is not applicable to your A/C. Nota 5: Deviations are also available into the ISI-00.00.00228_ .csv file for easy processing with office tools such as EXCEL. In addition, a macro is provided to allow the operator to automatically sort out the data by tab.

3. Procedure to use the ISI in CSV FORMAT with the associated macro Step 1: Unzip the file “ISI-00.00.00228_ .zip” Step 2: The csv file may be opened in office tool such as EXCEL or other application. In EXCEL, data will be displayed in text format, each field being separated by a “;”. Step 3: Use command “DATA / Text to column” if you want to display data sorted by column OR use the macro “ISI_BITE_Tools_Convert” to get the data sorted by TAB.

Once the csv file is opened (Step 2)  Double click on the file “Export XLS.xla”  Select ENABLE to enable the macro to run.  Click on macro “ISI BITE Tools Convert” to run the macro. Use the tabs to access the ISI sub-sections

Applicability All A318, A319, A320, A321 Airbus recommended action For all aircraft, Airbus recommends to perform:  MPD task 279000-07-1 “Operational check of EFCS by bite (Ground scanning)” every 750 FH.  MPD task 313000-04-1 “Read Centralized Fault Display System (CFDS)Post Flight Report (PFR) for maintenance messages from the Flight Data Interface Unit (FDIU)” every 600 FH. NOTE: To prevent possible loss of information, this task must be done before any other maintenance action on the FDIU.
