U.S. forces being maintained in a state of combat  readiness  for  deployment  to combat. b. DOD component programs and projects that are of comparable importance with item a. c.

To facilitate optimum material readiness, OPNAVINST  4616.1  series  authorizes  the assumption of the authorized higher FAD a maximum  of  90  days  prior  to  scheduled deployment   outside   CONUS   of   other authorized elevation from a lower to higher FAD. b.  Activities  performing  work  on  ships  during restricted availabilities are authorized to use the FAD of the ship being worked on when ordering material for that work. CONTROLLED  EQUIPAGE PROCEDURES Controlled equipage requires greater management control because the items are expensive, vulnerable to theft, and/or essential to the ship’s mission. Controlled equipage  is  listed  in  appendix  11  of  NAVSUP Publication  485(P-485).  The  department  head  must  sign for custody of all items marked by an asterisk in the list of equipage items. The  COSAL  SNSL-OSI  contains  allowances  of controlled   equipage   used   by   the   engineering department.  These  sources  provide  the  allowance authority, nomenclature, NSN, and allowed quantity for a ship. EQUIPAGE STOCK CARD AND CUSTODY RECORD The Equipage Stock Card and Custody Record, NAVSUP  306,  serves  a  dual  purpose  as  a  custody record and as an inventory control document. Its use is mandatory for all controlled equipage. Figure  5-12  shows  an  example  of  a  properly prepared NAVSUP 306 with representative entries. The form is prepared in duplicate. The supply officer keeps the original, and the custodial department keeps the copy. Supply is responsible for preparing the form, but the  following  guidelines  may  help  you  understand  its purpose  and  use. l l l l l l l l Items  requiring  custody  signature  are  identified on the NAVSUP 306. The responsible department is identified on each card. When two or more departments are responsible for individual pieces of equipment listed on one line of the allowance list, each department gets a card  showing  the  numerical  allowance  for  which the  department  is  responsible. The  cards  are  numbered  consecutively  for  each department. Each card shows the numerical allowance for each item as shown by the allowance list. When responsibility is divided, the total of all cards must equal the total allowance. The card shows the NSN and unit of issue, and the unit price if it is available. The card must show the allowance authority. The card must contain a complete description of the item, including serial numbers if the item is so  identified. Keep the department copy of the NAVSUP 306 current  by  posting  all  equipment  receipts  and expenditures as they occur. Each time supply personnel post  additional  transactions  to  the  original  NAVSUP 306, the department head will attest to the new balance by signing for items that require a signature. The custody records within the department are optional, but the copy of the NAVSUP 306 provides a 5-21
