(figs. 6-17 and 6-18). SRC cards are maintained as part of the aircraft logbook, AESR, or MSR as long as the component is installed in the aircraft or equipment. When the component is removed from the aircraft or equipment, the SRC card should be closed out, and the card accompanies the component. The card is also used to record the maintenance history on any item that requires monitoring, tracking, and trending of failure data by the CFA via the PMIC. The ATCM at COMNAVAIRSYSCOM maintains the central repository for aviation SRC cards. Copies of SRC cards updated after SDLM or rework and all new cards generated for new SRC card items are sent to this repository. You should forward misplaced and canceled SRC cards to this repository. This central repository responds to all requests for information regarding SCR cards. You should request this data by telephone, message, or letter consistent with the priority requirements for the information. When components are shipped between activities, the following procedures should be followed to reduce the possibility of loss or damage to the SRC card: The SRC card is inserted and sealed in a plastic, return material document envelope, and is not to be removed by anyone except the user or recipient. No other documents are to be placed in the same envelope with the SRC card. If the component is placed in a box or container for shipment, the SRC card (in the envelope) is attached to the component before the component is put in the box or container. Do not attach the SRC card to the outside of the shipping container. If the component is shipped in an open crate or without a container, make sure the envelope that contains the SRC card is securely attached to the component. Directions for maintaining SRC cards are in the NAVAIR 01-XXXX-6 series of PMICs when the PMICs are under the NAVAIR Publication Numbering System. When PMICs are under the Technical Manual Identification Numbering System, you should follow directions provided for publications in the A1-XXXXX-MRC-000 series of PMICs. NOTE: The Xs in the above publication numbers stand for aircraft or manufacturer designators and vary from aircraft to aircraft and manufacturer to manufacturer. Original SRC cards are initiated as follows: SRC cards for components installed on, or delivered with, major aeronautical equipments (such as aircraft and engines) are the responsibility of the activity that accepts such major equipment for the Navy. The delivery point ensures the SRC cards are copied, and that a copy is forwarded to the ATCM Central Repository at COM- NAVAIRSYSCOM. SRC cards for new components received into the Navy supply system are the responsibility of the original activity that accepts such components for the Navy. The original activity forwards a copy of all SRC cards to the ATCM Central Repository at COMNAVAIRSYSCOM. An SRC card is kept current during rework. Upon completion of rework, the SRC card that reflects the current status of the component is copied, and a copy is forwarded by the NADEP to the central repository. This procedure applies to components reworked individually and concurrently as part of an aircraft rework process. The SRC card should be attached to components returned to the supply system as spares or inserted in the aircraft logbook, as appropriate. When SRC cards become damaged or mutilated, the activity that has current custody initiates a new card, and transcribes all information to the new card. When notified that SRC cards are no longer required via a change to the applicable NAVAIR 01-XXXX-6 manuals, reporting custodians should annotate the affected SRC cards to show the deletion authorization. Reporting custodians should then forward the cards to the central repository for purging from the master file. Card maintenance is important, and all of the required data should be entered. When a card contains no space for additional entries, a new card should be prepared. First, verify that the Identification Data section, including the Replacement Interval and Replacement Due blocks, is complete and accurate. Replacement intervals are outlined in applicable PMICs. Replacement due is computed at the time of the installation of the component and equals total hours or counts on the aircraft or equipment plus the replacement interval minus the hours or counts on the 6-27
