applicable aircraft or equipment serial number
effected. Also, reference material that applies to the
package is listed here. The title page also has a small
index that outlines the WP coverage and an applicable
technical directive listing. A listing of support
equipment and material required to perform the task is
in the front of the text. This information will give you
an idea of the task before you begin the work. A typical
WP title page is shown in figure 2-5.
Content Format. Content format depends on the
specific task to be performed, the authorized depth of
information required and the sequence of
performance. Work packaging provides the flexibility
to arrange content to meet system or component design
criteria, construction, and selected repair. Work
packaging is tailored to fit the specific maintenance
demands of the unit under repair.
Organizational data is system oriented.
Organizational system maintenance covers
installation, removal, alignment, and adjustment in
task order. Descriptive information and principles of
operation data are in the order of operational signal
flow or mechanical operating sequence by component.
Testing and troubleshooting are organized by
functional block logic and by action sequence with
consideration given to mode selection and failure
probability. Where possible, specific points of entry to
the text are identified to preclude the necessity of
running a complete end-to-end test after each
corrective action. IPBs are in a format that is
compatible with the other volumes by system and WP
alignment.
Intermediate- and depot-level manuals are based
on component rather than system breakdown. Most
intermediate- and depot-level WPs are organized in a
pyramid fashion based on standard top-down
breakdown of the component, as shown in figure 2-6.
Where the volume of data permits, end item
description, principles of operation, and
troubleshooting appear as a series of introductory WPs
preceding the maintenance data. The first WP would
then cover the removal/installation and IPB of
components from/on the end item. Tasks then follow
through the disassembly/assembly of the removed
components. The type of information contained in
each WP is shown in figure 2-7. Note that parts
replacement IPB data is in the intermediate/depot WP.
This data provides maximum information in support
of the total package concept.
