(1)
Some of the exploded view illustrations shown in the ILLUSTRATED PARTS LIST (IPL
33-30-15-10000) section are also referenced in the DISASSEMBLY (PGBLK 33-30-15-3000),
CLEANING (PGBLK 33-30-15-4000), INSPECTION/CHECK (PGBLK 33-30-15-5000),

Application of Maintenance Task Oriented Support System (MTOSS) (Subtask 33-30-15-
99F-007-A01)
(1)
In accordance with the ATA Specification 2200, this publication uses a Maintenance Task
Numbering System which make the maintenance procedures in this manual compatible with
an automated shop environment.
(2)
The system uses standard and unique number combinations to identify maintenance tasks
and subtasks.
(3)
The MTOSS structure is the logical approach to organizing maintenance tasks and subtasks.
The MTOSS numbering system includes the ATA Chapter-Section-Subject number as well as a
function code and unique identifiers. The purpose of incorporating the MTOSS numbering
system is to provide a means for the automated sorting, retrieval, and management of
digitized data.
(4)
Section and Sub-section Numbering System
(a)
All procedures in this publication have TASK and SUBTASK numbers at key data retrieval
points. The numbers provide the following:
• Identification of the hardware (part or parts) primary to the TASK
• Identification of the maintenance function applied to the part or parts
• A unique identifier for a set of instructions (known as TASK or SUBTASK)
• Identification of alternate methods and configuration differences that change the
procedure applied to the TASK
• Identification of airline changes to a TASK or SUBTASK.
(5)
Components of TASK and SUBTASK Number
(a)
The numbering system is an expansion of the ATA three-element numbering system. The
number has seven elements. The first five elements are necessary for each TASK or
SUBTASK. The sixth and seventh elements are applied only when necessary. Refer to
Figure INTRO-3.
(b)
Elements 1, 2, and 3 identify the ATA Chapter-Section-Subject number of the page block.
(c)
Element 4 defines the maintenance function being performed. This element is a three
position element. The third position is zero filled when further definition is not required. If
required, the manufacturer will use the numbers 1 thru 9 or letters A thru Z, excluding the
letters I and O. Refer to Table INTRO-2.
(d)
Element 5 provides a unique identification for each TASK or SUBTASK number, which is
similarly numbered through the first four elements.
