number, naval aviation depot (NADEP) customer service, or as instructed by the CFA. l Register all parcel post shipments. l On the DD Form 1348-1 shipping docu- ment, stamp EI in 3-inch letters on the face without obliterating any vital data elements. In the Ship to block, enter the words Investigation Material and the control number. The supply department may not retain the material longer than the 30-day time limit. This time limit allows adequate time for the maintenance engineering cognizant field activity (MECFA) to report shipment of the deficient material. TOOL CONTROL PROGRAM This program provides a means to rapidly account for all tools after completing a maintenance task, thus reducing the potential for foreign object damage (FOD). The material control officer coordinates the tool control program (TCP) and guarantees tools are procured and issued in a controlled manner consistent with the approved tool control plan (TCPL). TOOL CONTAINERS The exterior of all toolboxes or rollaways used for maintenance must clearly identify the organization, work center, and tool container number. The tools contained in the toolboxes must be etched with the organization code, work center code, and the container number. Special accountability procedures must be established locally for those tools not suitable for etching; for example, jewelers’ screwdrivers. Each tool must be placed in a silhouetted con- tainer against a contrasting background. The silhouetted tool outline highlights each tool loca- tion within the container. Those containers not silhouetted must contain a diagram of the tool locations. Additionally, they must include a separate listing of tools in calibration or requiring replacement. AIRCRAFT INVENTORY RECORD The AIR is used to establish a formal, continuous chain of accountability for specific equipment installed on or designated for use on any aircraft. The AIR is applicable to all aircraft and lists selected material and equipment account- able by all Navy organizations that are assigned or physically possess operational aircraft. The AIR is prepared by the aircraft manufacturer and is delivered with each individual aircraft. Aircraft Transfer and Acceptance When an aircraft is to be transferred on site, designated inventory teams from the transferring and accepting activities jointly inventory the air- craft and record, in the appropriate column of the AIR Equipment List, OPNAV Form 4790/111, the quantity of each item on board the aircraft at the time of transfer. The AIR Shortages, OPNAV Form 4790/112, is completed to identify shortages of AIR items and mission essential subsystems matrix (MESM) related equipment that are not available for transfer, concurrent with the aircraft. When a ferry pilot is required to effect an air- craft transfer, two inventories are made—one before the ferry flight by the transferring activity and one on completion of transfer by the accepting activity. The ferry pilot does not participate in the inventories except to accept custody of pilferable and classified equipment from the transferring ac- tivity and to transfer custody of the items to the accepting activity. AIR items that cannot be placed on the air- craft for transfer are shipped separately marked as AIR Equipment for Aircraft Bureau Number (BUNO). A note to indicate such shipments is made in column E of the AIR equipment list opposite each affected equipment. Immediately upon receipt of notification of transfer, the transferring activity inventories all equipment specifically assigned to the aircraft (AIR and MESM equipment), including all items that cannot be placed aboard the aircraft for transfer, and then lists such equipment on a DD Form 1149. This loose equipment is turned in to supply for appropriate shipment to the receiving activity. A receipt copy of the DD Form 1149 is 5-4
