Entry in trouble shooting process is required,when a fault is reported by the For example, there has been made the following entry in the log book:

local indications or crew observations require an immediate usage of the TSM
(Trouble Shooting Manual). The timedifference of the two datafields may be max. 5 minutes ( in the exam-
ple : 1minute ).
In the following the use of the TSM and some other aircraft documentations is
described. This includes the description of the layout of the TSM. When you can find a corresponding FAULT-message , you have to report it
the log book ( ACTION field ).
The philosophy of the troubleshooting manual is to guide the trouble shooter
from a reported fault ( log book entry, CMS post flight report, ECAM status, When there is no FAULT message in the PFR , you have to report in the log
crew observations ) to a correct procedure to isolate the fault. book:
”No CMS FAULT message”.
If you use ATA 2613 ..(COCKPIT EFFECT COLUMN) as a reference , you will
find in the FAULTS column (ATA 261315) the fault message:
”APU FIRE LOOP A(21WG)/FDU APU(13WG) .
As you can see from the UTC/ FLIGHT PHASE column the FAULT occurred at
16 h 39 min (Climb). The COCKPIT EFFEKT appeared at 16h40min (Cruise)
For Training Purposes Only

The time of occurrence of both messages is within the limits.

Next step of trouble shooting :
Confirmation of the ECAM/FAULT messages.
Normally the confirmation is done by a test .
Because there are several tests possible for different systems, you have to go
first to the TSM to find out, which one is the right one.

INDEX OF WARNINGS/MALFUNCTIONS (I-W/M)

This part of the TSM contains a list of the following:
S I-ECAM (ECAM)
- EWD Warning(s)
- STS-Maintenance (SD)
- SD-Flag(s)
- SD-Advisory(ies)
S I-EFIS (EFIS)
- PFD-Flag(s)
- ND-Flag(s)
S I-LOCAL(Local Warnings/Cautions)
S I-OBSV (Observations / Crew/Maintenance)
In the particular groups the informations are alphabetically sorted.
For the troubleshooting the I-W/M serves as an introduction to the TSM, be-
cause you can see whether the warning message (COCKPIT EFFECT) from
the CMS PFR(Post Flight Report) and /or the message from the log book is
covered in the TSM or not.
With the information of the ATA chapter and subchapter in the I-W/M the fur-
ther way of troubleshooting in the TSM Standard ATA chapters is determined.
In the troubleshooting example you can find the warning message under EWD
Warning(s) in the Index of Warnings/Malfunctions:

The list is sorted alphabetically.
For troubleshooting the I-CMS also serves as an entry point as the I-W/M be-
fore.
Here you can see whether the FAULT message (FAULTS) from the CMS PFR
is covered in the TSM or not.
In the troubleshooting exercise you can find the FAULT message in the I-CMS:

STANDARD ATA CHAPTERS

General
After you have confirmed, that the pilots report (log book) and /or a correlating
FAULT message are covered in the TSM, you go to the specific ATA chap-
ter.(Example: CHAPTER 26)
Each ATA chapter is broken down into sections (SE) and sub-chapters (SU C).
The same structure is used as in the maintenance manual, but only chapter
and sections are usd in the TSM. (Example: 26-13-00)
Each ATA chapter contains a table of contents(see Figure 6).
For each sub section the structure is the same:
S Fault Symptoms (Page Block 101)
S Fault Isolation Procedures (Page Block 201)
S Block Diagrams (Page Block 301)
Corresponding to the data in the POST FLIGHT REPORT,
Page Block 101 (FAULT SYMPTOMS) will be selected first.

Fault Symptoms (Page Block 101)
ATA Page Block 101(page 101-199) consists of :
S Fault List
S Identifier List
It contains all warnings/malfunctions and the corresponding CMS fault mes-
sages, that are available for the ATA sub-chapter.
In the column CMS FAULT MESSAGES following data are listed:
S SOURCE (source of the message)
S MESSAGE (Fault message)
S IDENT(identifiers,systems that are influenced by the failure)
S ATA (ATA Chapter)
S C (Failure Class)
In column IDENT numbers or ”NONE” is shown.
If for a given fault symptom many identifiers are involved, it is not possible to
show them in the column. Therefore they are shown in coded form. On a spe-
cific page the content of each fault identifier code is shown (for exam-
ple:1=AFS, DMC3, FWS; 2=DMC2, EFCS1, ACMS etc.)
In the TASK column there is shown the fault isolation procedure number. This
is the entry point for further fault isolation.These task numbers belong to the
AMTOSS (Aircraft Maintenance Task Oriented Support System).
All maintenance actions (routine /non-routine) are described in different docu-
ments under task /sub-task numbers
With the TASK number you will find the fault isolation procedure in:
Page Block 201
For the trouble shooting exercise the TASK number is:

261300 810 801

The first six digits show the ATA chapter in the TSM.
The following six digits (......810 801) show the fault isolation procedure for the
specific fault.

Fault Isolation Procedures (Page Block 201)
To comply with technical requirements and maintenance task requirements, the
invariable structure of Page Block201 (Page 201-299) is as follows:
S Possible Causes
S Job Set-up Information
S Fault Confirmation
S Fault Isolation
S Close-Up
After selecting the ATA chapter (in the exercise: 26-13-00), you get to the spe-
cific fault isolation procedure by the task number(in the exercise: .....-810-801)
4. Possible Causes
Shows all the LRU(s) that might be replaced during the fault isolation pro-
cedure. Suspect wiring ,pipes , coaxial cables etc ...are also shown.
5. Job Set-up Information
Gives a reference to documents(AMM, ASM etc...), where you can find the
tasks that must be done, before the trouble shooting procedure can be
started.
6. Fault Confirmation
In order to prevent unjustified troubleshooting, the fault should be confirmed
(when possible) prior to troubleshoot the system. The fault can be con-
firmed by BITE tests, operational tests or functional tests.
7. Fault Isolation
When a fault is confirmed, you have to follow the fault isolation procedure
that is described in this section. After performing the fault isolation proce-
dure you should do a test, to check correct operation.

8. Close-Up
Depending on the fault confirmation and /or fault isolation, a close-up pro-
cedure may be necessary in order to put the aircraft back to its initial con-
figuration.
