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. Figure 2-6.—Typical intermediate/depot technical manual assembly. 2-6
