COMPONENT LOCATION
The numbering and designation of systems in this section are based
on ATA Spec. 100. The parts within each system are identified by their
functional description and, when necessary, by door or panel
identification, followed by the appropriate figure.
The access doors and panels in a zone are identified by an
alphanumeric system which has three digits. They identify the zone
where the access door or panel is located, followed by a two-letter or
three-letter suffix.
− The first digit indicates a major zone of the airplane, which gives
the necessary reference for the identification of the service
areas or components:
MAJOR ZONE AREA
100 Lower fuselage (below the floor line)
200 Upper fuselage (above the floor line)
300 Tail cone and empennage group
400 Powerplant and nacelles
500 Left half-wing
600 Right half-wing
700 Landing gear wheel well doors
800 Doors (main, service, cargo, emergency)
− The following two digits indicates sub-zones. For example:
111 - Radome; 510 - Wing Leading Edge.
− The first letter identifies a sequence which starts with the letter
A.
− The second letter shows the location of each access door or
panel in relation to the aircraft as follows:
B: Bottom T: Top
L: Left R: Right
− Each panel gets a fastener identification code, boxed, which
identifies the type and quantity of the fasteners for each panel.
L: Latch
S: Screw
C: Camloc
For further details on this system, please see Airplane Maintenance
Manual, Chapter 6, for the part identification.
