The following list of systems,sub-systems and titles shows examples of the breakdown of a 'TYPICAL' manual according to ATA100.
the major divisions are termed 'Groups' ,each group being divided into Chapters and allocated blocks of chapter numbers. Thus:-
GROUP CHAPTER NUMBERS
Aircraft General 1-19
Aircraft Systems 20-49
Structures 50-59
Propellers/Rotor 60-69
Power Plant 70-89
Each chapter is arranged alphabetically in a group and is divided into sections and then sub-divided into subjects designated by a 'dash number'
e.g.
24-21-8
Chapter section subject
24 -21 -8
Electrical -Main Generation -Voltage
Power regulator
e.g.
52-10-2
52 -10 -2
Doors -Passenger/Crew -Rear door
Passenger
Each subjectis then further divided into page groups in blocks of 100 assigned as follows:-
1-100 Description and Operation
101-200 Trouble Shooting
201-300 Maintenance practices
So,
52-10-2-95 may give a desription of how the door handle locks
52-10-2-125 may give an indication of what to look for if the door doesn't lock
52-10-2-225 might tell you how to remove the defective door lock. etc
Her are some Chapters that might deal with as an 'insty'
Chapter 22 Auto Flight

10 Auto Pilot
20 Speed-Attitude Correction
30 Auto Throttle
Chapter 23 COMMUNICATIONS
00 General

Chapter 31 INDICATING/RECORDING

20 Unassigned
30 Recorders
40 Central Computers

Chapter 39 ELECTRICAL/ELECTRONIC PANELS

00 General
10 Instument and control panels
20 Electronic Equipment racks
Chapter 77 ENGINE INDICATING
00 General
10 Power

30 Analysers
As you can see it does not really matter what A/C you work on as long as it conforms to ATA100 you will be able to find the correct part of the correct manual to solve your problem (SURE !) as it will always be in the same place.
This is the basic typical gist if there are any glaring mistekes in my text I'm sure somebody will correct me.
GOOD LUCK.
