Identification number: Nine-digit identifying number assigned by SPCC to a particular item or component of equipment. This number is shown at the top and the bottom of the page. Date:  COSAL  publication  date. Page:  Consecutive  numbering  of  all  pages required  to  describe  one  equipment/component that is identified by a single APL number. This is shown at both the top and the bottom of the page. APLs have the word  END printed  in  the center of the page immediately following the last line of data for that APL. This ensures that a complete APL is available. Characteristics: Complete nameplate data on the equipment/component named in item 1. Reference/symbol  number:  A  number,  other than an NSN, by which a part may be identified, arranged in alphanumeric sequence. It may be a manufacturer’s part, drawing, piece, or circuit symbol  number. Additional  data  area:  When  additional  technical manuals or plans apply, they are listed in this area under an appropriate caption. These are in addition to those listed in items 2 and 6. Item name: The name listing of repair parts and/or related accessory components for the equipment/component  covered  by  the  APL. Stock  number:  The  FSN  assigned  to  a  specific repair part. When an FSN has not been assigned, the reference number from item 7 is repeated. Accessory  components  applicable  to  a  “parent equipment”: These are listed on the parent APL. Federal  supply  code  for  manufacturing  (FSCM): This code lists the manufacturer of the part. Part militarv essentiality code (PART MEC): These are two codes. They are shown on the APL and the SNSL. 1. Failure of the part would have a major effect on  the  operation  of  the  component. 2. Failure of the part would have little effect on the operation of the component. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. AL Source code: Shows the availability of repair parts and the method of procurement. These codes  are  defined  in  the  introduction. Maintenance  code:  A  three-digit  code  that identifies the maintenance activity authorized to replace, repair, and condemn an item. Only the first digit is now used. These codes are defined in the introduction. Recoverability/condemnation  code:  Indicates the   recoverability   characteristics   of   items removed  during  maintenance. Z - Repair Part D - Spare Part Allowance  notes  code:  Provides  necessary  and important  information  about  individual  items listed on the APL. The introduction lists and defines  these  codes. Quantity  in  one  equipment/component:  The total   population   of   the   part   within   the equipment/component described by the APL. Unit of issue: The smallest quantity of a stock item that can be issued. Allowance   item   code:   Reserved   for   future COSAL  use. On  board  allowance  table:  APLs  published  as part of an allowance list for shipboard use  will not  have  quantities  printed  in  these  columns. Instead,  SEE  SNSL  FOR  ALLOW  will  be printed. APLs received after the regular COSAL will have the quantities shown. Ship type and hull number: The specific ship for which the APL is published. Page: Consecutive page numbering from first page to last page of all APL pages contained in the COSAL. Identification number: Same as item 3. Date: Same as item 4. Page: Same as item 5. LOWANCE EQUIPAGE AEL is similar in appearance to following   differences: LIST (AEL).–  The the APL with the 1.  The  APL  provides  maintenance  and  repair support for ship’s equipment, and the AEL provides allowances  of  equipage  and  supplies  necessary  to support  the  ship’s  mission. 5-10
