used in the Directive Issuance System are instructions, notices, and change transmittals. Instructions are directives that contain information of a continuing nature or require continuing action. An instruction has a continuing reference value, and is effective until the originator cancels or supersedes it. Notices are directives of a onetime nature or that contain information or require action applicable for a brief period only. A notice has the same force and effect as an instruction, but it does not have permanent value. Therefore, it contains provisions for its own cancellation. When the exact length of time a notice is to remain in effect cannot be determined at the time of issuance, the specific date for record purposes is set far enough in the future to allow all necessary use of the notice. A change transmittal is the medium used to transmit changes to an instruction or, under extenuating circumstances, a notice. Each transmittal describes the nature of the change and gives directions for making them. Directives are identified by designation information. Using “SECNAVINST 5215.1” as an example, “SECNAV” is the issuing authority, “INST’ is the type of directive, “5215” is the subject identification number,   “1” is the consecutive numbering for instructions by the directive control point. The consecutive numbers assigned to instructions, which are later canceled, are not reused. The period (.) is used to separate the subject identification and consecutive numbering. When a change is made, the change transmittal number and its date are shown on the page(s) that contain(s) the change; for example, SECNAVINST 5215.1, Change Transmittal 1, 26 Jan 1993.” A revised instruction will retain all the designation information with the addition of a suffix capital letter (the first revision “A,” the second “B,” etc.) immediately following the consecutive number. Each change transmittal is identified in the designation line of the transmittal by the same number as the directive it changes (in the case of notices, the date), plus an assigned change transmittal number added to the identification; for example, “SECNAVINST 5215.2, Change Transmittal 1.” You will use different instructions and notices when performing your daily tasks. They are issued by various commands, bureaus, ships, stations, and operating forces. Many of the directives used in aircraft maintenance are issued by Headquarters, Naval Air Systems Command. They are known as NAVAIR instructions or notices. The directives issued by Chief of Naval Operations are known as OPNAV instructions or notices. Refer to Department of the Navy Directives Issuance System, SECNAVINST 5215.1, for more information. The NAMP, OPNAVINST 4790.2 (series), is sponsored and directed by the Chief of Naval Operations (CNO). It addresses CNO concepts, objectives, policies, programs, organizations, and responsibilities as they apply to aviation maintenance for each level of command. This instruction outlines the duties and responsibilities of a supervisor working in the material control division of a squadron or AIMD, or in the aviation support division of the supply department. The Uniform Material Movement and Issue Priority System (UMMIPS), OPNAVINST 4614.1F, contains the following information: l l l l l l l Force activity designator (F/AD) Issue policy designator Requisition processing Delivery dating Mission essential material Abuses and policing of the priority system Expedited handling of critically needed items The Shore and Fleet Small Purchase and Other Simplified Purchase Procedures, NAVSUPINST 4200.85 (series), provides instruction and guidance concerning purchase or procurement of material from commercial suppliers. This instruction was written to implement and supplement the Federal Acquisition Regulation (FAR) and the Department of Defense Federal Acquisition Regulation Supplement (DFARS). The Fleet Use of MILSTRIP, NAVSUPINST 4235.3, is designed to be used for indoctrination and training of fleet personnel. It contains illustrations and explanations that make it a valuable training aid as well as a handy reference. You will often be required to prepare or process requisitions for component parts required for incorporation of technical directives (TDs). A TD may direct that component parts or material be added, removed, changed, altered, relocated, or repositioned. NAVAIR has management responsibility for the Configuration Management Program. NAVAIRINST 5218.8 contains specific information concerning the TD program. Additional information concerning TD compliance at the O, I, and D levels of maintenance, documentation procedures, and reporting requirements 2-9
