volume contains a general description of the aircraft, information that is not contained in other specialized manuals, and all information about servicing the aircraft. Each of the specialized system volumes of the MIM is further divided into four sections. These sections are described briefly in the following paragraphs. Section I is the same in all volumes for a particular aircraft MIM. It introduces the manual and usually supplies a list of the changes that apply to the particular volume. Section II describes the system and its components, as well as their operation. Section III covers such maintenance as the removal and installation procedures and troubleshooting charts for organizational-level maintenance. Section IV covers component repair procedures for intermediate-level maintenance. Figure 2-18 is an example of a page from section III of a MIM. This page shows the basic layout of the maintenance-coverage sections of the specialized-type manuals. To make it easier for you to locate the material on the page, each component maintenance procedure is identified by a boldface heading (fig. 2-18, A). All removal and installation procedures provide a recommended manpower requirement (B) for the supervisors to use in assigning personnel to perform the job. All tools and equipment, other than standard tools, are noted (C) before the maintenance procedure. This allows these items to be drawn from the toolroom before starting the operation. When consumable materials, such as lubricants, lockwire, and cotter pins, are required during an installation procedure, a listing of these items (D) is made before the procedural steps. Miscellaneous small parts (other than standard Air Force/Navy [AN] specification and Military Specification [MS] hardware), necessary for removal and installation. also appear in the materials list. As an aid to quality assurance representatives (QARs), those steps in a procedure that require an inspection are in italics (E). NOTE: In some MIMs, the steps in a procedure that require a quality assurance (QA) inspection are underlined. The italicized steps are a very important feature and are summarized (callout F) at the end of each procedure. The separate sections of these manuals are issued as separate publications under individual identifying numbers. This is done to make it easier for maintenance personnel to procure, store, file, and use specific parts of the manual. A new format for MIMs was developed with the introduction of manuals for late model aircraft, such as the F-14 and S-3. You should understand this newer format as well as the old because you will use both, depending upon the aircraft on which you are working. Both formats are discussed separately in the following paragraphs. Under the older format, a volume contains several sections. The number of sections in each volume may differ from one model aircraft to another and from one volume to another. In some cases, organizational maintenance is covered in one section and intermediate maintenance in another. In other cases, two separate volumes cover the two levels of maintenance. In the newer format, sections I and II of all volumes are usually similar in format. Section I is an introduction to the volume. It provides a general description of the manual, including the scope of coverage, format, and arrangement of the included information. Also, it contains a list of the applicable publications and technical directives required by maintenance activities. Section II contains a physical description of the equipment or systems covered in the volume. For example, in the volume   “Powerplant and Related Systems of the F-14 Aircraft,” section II contains descriptions and operating instructions for the power plant and its related systems. In some volumes, a section is devoted to any support and special equipment required for the maintenance of the system covered. In other volumes, this information is covered in the section that pertains to the specific system. As stated previously, the remaining number of sections may differ; however, in all cases these sections contain the maintenance information for the included systems. Under the newer format, the MIM is subject-identified in part IV of the manual number code. For example, the manual number codes for the F-14 organizational-level MIM are shown in figure 2-18
