Description of COSAL Parts and Sections

Figure 3-1.—Summary of effective allowance parts/equipage lists (SOEAPL). Description of COSAL Parts and Sections Since the COSAL and COSBAL are similar, we will describe just the COSAL parts and sections. Certain aviation components (aviation supply offices [ASOs]) will also be included in the COSAL when specifically designated. For more information and complete instructions in the use of the COSAL, we recommend that you read the COSAL Use and Maintenance Manual, SPCCINST 4441.170. Each COSAL publication is produced in three parts. Part I contains indexes. Part II contains associated APLs and AELs. Part III contains allowances and cross- reference data. The three parts are subdivided as follows: Part I Summary of Effective Allowance Parts/Equipage Lists (SOEAPL) Index–Section A (Equipment Nomenclature Sequence) Index-Sections B, C, D, and E Part II Section A–Allowance Parts Lists (APLs) Section B–Circuit Symbol Data (microfiche only) Section C–Allowance Equipage Lists (AEL) Part III Section A-Storeroom Items (SRI) Stock Number Sequence List (SNSL) Section B-Operating Space Items (OSI) Stock Number Sequence List (SNSL) Section CF–Maintenance Assistance Module (MAM) Section CR–Ready Service Spares (RSS) Section D–Alternate Number Cross-Reference to Stock Number Section E–General Use Consumables List (GUCL) Section F–Forms and Publications The following paragraphs provide a brief description of the parts of the COSAL listed above: PART I-SUMMARY.— The Summary of Effective Allowance Parts/Equipage Lists (SOEAPL) is a numerical listing of all APLs and AELs used to determine how many of each part is listed on the stock number sequence list (SNSL).
