CHAPTER 6

REPAIR CYCLE

Section 6A—REPAIR CYCLE PROCEDURES.

6.1. Chapter Summary. This chapter explains the concept of the repair cycle process. This process establishes control of all unserviceable repair cycle assets from the time they are generated until returned to the Logistics Readiness Squadron/supply activity as serviceable or unserviceable. The FSC is the Logistics Readiness Squadron/supply activity function responsible for managing the repair cycle process.

Repair cycle assets are items with ERRCD of XD(x) or XF(x). They are also known as DIFM items. The objective of the repair cycle concept is to obtain the greatest benefits from the base maintenance shops.

The process establishes firm control over repair cycle assets to make sure they are repaired at base-level or sent to a repair facility as fast as possible. The repair cycle time of an item starts when the unservice-able item is removed from the aircraft or piece of equipment, and a demand is made on the Logistics Readiness Squadron/supply activity for a replacement. It stops when the item, either serviceable or unser-viceable, is sent back to Logistics Readiness Squadron/supply activity. It is important to know that Logis-tics Readiness Squadron/supply activity will not order a replacement item until it is determined that the unserviceable item cannot be repaired on base, or the item is condemned. So, unserviceable repair cycle items must be processed through the repair shops as quickly as possible. Status of repair cycle items must be continually maintained and updated according to Attachment 6A-1.

6.2. Overview. The repair cycle process establishes firm control over repair cycle assets and obtains the greatest benefits from the base maintenance shops. This section explains the system concept and provides the procedures for effective use of the repair cycle process.

6.3. DIFM Issue Procedure.

6.3.1. DIFM Control. Issue requests for ERRCD XD or XF with activity codes X (expedite), R (rou-tine maintenance), or S (supply point) and with demand code R (recurring) or N (nonrecurring) will place that transaction and the item under DIFM control. All issues to Contract Maintenance (activity code C) are put under DIFM control regardless of the ERRCD or demand code.

6.3.2. Multiple DIFM Indicator. Usually, DIFM issues are for a quantity of one each; therefore, the computer system in the Logistics Readiness Squadron/supply activity is programmed to reject a DIFM issue for more than one each of an item. The major reason behind this is the possibility of hav-ing a different maintenance action taken codes assigned when multiples are issued on the same docu-ment number. Although the norm is one each per document number, there may be cases where this is not reasonable (for example, turbine blades and tires). When this happens, call the FSC of the Mate-riel Management Flight in the Logistics Readiness Squadron/supply activity. Explain your situation and, if approved, they will assign a multiple DIFM indicator to allow DIFM issue requests for multi-ple quantities. When using this procedure, there is only one document number. If five each are returned with an action taken code 9, and the other five are returned with an action taken code B, it will be necessary to process separate turn-ins with the same document number.

6.3.3. Maintenance Turnarounds. Repair cycle items may be removed from the end-item, repaired, and reinstalled without a demand being placed on Logistics Readiness Squadron/supply activity or after Logistics Readiness Squadron/supply activity confirms that the serviceable asset is not available from their stocks. The repaired asset is not physically processed through the Logistics Readiness 6–1

AFMAN 23-110 Volume 2 Part 13, Chapter 6 Squadron/supply activity; however, the maintenance activity must give the FSC the information needed to update supply records. The term frequently used to record this type transaction is mainte-nance TRNs. It is very important to document each repair made on repair cycle items. Inform the FSC every time a repair action is taken and prepare the necessary documentation, FSC Form 350, Reparable Item Processing Tag. Send the bottom portion of the AFTO Form 350 to the RCSS, ensure it is completely filled out to include the maintenance action taken code. The maintenance action taken code for TRNs must be A, F, G, K, L, or Z. Invalid AFTO Forms 350 will be returned to the appropriate maintenance activity for action. Failure to inform the Logistics Readiness Squadron/sup-ply activity about TRNs reduces the number of serviceable items the Logistics Readiness Squadron/ supply activity can keep on hand. Logistics Readiness Squadron/supply activity's objective is to have serviceable items on hand to replace an item that has failed. This allows the unserviceable item to be processed through the repair cycle process on a scheduled basis.

6.4. DIFM Turn-In. DIFM assets are returned to the Logistics Readiness Squadron/supply activity through the FSC. The FSC processes and controls all DIFM assets. A completed AFTO Form 350, a con-dition tag (DD Form 1574, 1575, or 1577-2), and the number 3 copy of the original issue or due-out release document (DD Form 1348-1A) must be provided when items are turned in to the FSC (see Attachment 6A-2, Maintenance and Supply Action Taken Codes).

6.5. DIFM Update.

6.5.1. Item Status/Location Change. To accurately control DIFM assets, the status and location of the item must be known. When items are received in a shop or when the status changes, the shop scheduler or work center supervisor must inform the FSC. FSC personnel update the location and sta-tus of the item in SBSS records. An example of a status change would be when an item goes from AWM to INW. A location change occurs when an item is moved from one shop to another. Mainte-nance personnel that are under the CAMS use CAMS to update the SBSS when the location and sta-tus of an item has changed.

6.5.2. DIFM Status Codes. DIFM items must be returned to the Logisitics Readiness Squadron/sup-ply activity as quickly as possible. The DIFM managers in Supply and Maintenance must make every effort to process repair cycle items as fast as possible. MAJCOMs may assign other status codes to cover special situations in their command. (See Attachment 6A-1 for DIFM status codes.) Each day, the SBLC generates a repair cycle asset management list (D23/NGV905). This listing is for-warded to each shop and the FSC as an aid in managing and controlling DIFM assets. When differ-ences exist between the DIFM status or location as shown on the DIFM list and the actual status or location, the FSC must be informed to ensure updates are made.

6.6. DIFM Reconciliation. DIFM reconciliation between the Logistics Readiness Squadron/supply activity and the maintenance activities is conducted by use of the D23/NGV905. Copies of the applicable sections of this report are furnished to each maintenance activity to verify the location of the issued items.

Flight Service Center personnel will update the DIFM details with the current item location and current DIFM status when maintenance provides the required changes.

6.7. Base Contract Maintenance. DIFM items needing contract maintenance are issued directly to that activity by maintenance. After the item is repaired, maintenance personnel return the item to the Logistics Readiness Squadron/supply activity as a serviceable asset.

6–2

6.8. Discrepancy Report Exhibits. Items identified to show materiel deficiencies conditions are pro-cessed as unserviceable Discrepancy Report exhibit turn-ins by the FSC and forwarded to Inspection for final processing. Action taken code C is used on turn-ins for Discrepancy Reports according to TO-00- 35D-54. If storage space is available, the Logistics Readiness Squadron/supply activity stores Discrep-ancy Report exhibits until final disposition instructions are received.

6.9. Buildup Items. Repair cycle items requiring buildup before use are identified and accounted for on supply point records. Normally, maintenance personnel operate these buildup points. Each time a buildup item is removed from the supply point to replace a like item removed from an end-item, the indi-vidual responsible for the supply point will advise the FSC.

6.10. Time Change Requirements. Forecasting requirements are limited to specific time change items in TO 00-20-9. Quarterly, Maintenance Materiel Control personnel make a forecast which covers a 1-year period. To get the assets from the Logistics Readiness Squadron/supply activity , Maintenance Mate-riel Control personnel prepare an AF Form 2005 issue request to order time change items up to 60 days (but not less than 10 days) prior to the need date. Physical issue of the asset is not made until Mainte-nance Materiel Control personnel verify the scheduled time change date is firm.

6.11. TCTO Kits.

6.11.1. General Information. This paragraph explains how to get TCTO kits needed for a technical order modification on an aircraft or missile, an end-item of equipment, or spare parts or components.

Air Force policy and procedures on TCTO management are in AFI 21-101, Maintenance Manage-ment Policy, and TO 00-5-15. The term "kit" refers to all the parts and materiel required to complete a technical order modification.

6.11.2. TCTO Kits Requirements. Requirements for TCTO kits or parts needed to assemble a kit are submitted to the FSC on an AF Form 2001. After the request is received, FSC personnel requisition the kit from the depot, if it is a depot assembled kit. If the kit is assembled at the base, the parts are obtained from Logistics Readiness Squadron/supply activity stocks or from normal supply sources.

In this case, the FSC is responsible for assembling the kit. When the kits are received or assembled, they are stored by the FSC. The FSC notifies the requesting activity that they are available. Nor-mally, TCTO modifications are made as scheduled maintenance. When the kits are needed, the requester notifies the FSC and the kits are issued.

6.11.3. Control of TCTO Kits. The FSC stores the kits until they are needed by Maintenance. Con-trols are set up to prevent loss or unauthorized use of the kits or their components. The maintenance activity makes sure the kits are installed on the designated end-item of equipment. If a kit is issued for a specific end-item of equipment and used on another end-item, the maintenance activity must notify the FSC and Maintenance Materiel Control. The maintenance activity must also advise FSC personnel of any aircraft or other end-item transfers as far in advance of the transfer as possible. FSC personnel ship the kits for the transferred equipment to the gaining base or organization according to TOs 00-5-15 and 00-25-4.

6.11.4. TCTO Kit Assets. These assets are reconciled with Supply on a monthly basis. The reconcil-iation is used to update TCTO kit status. Maintenance advises the Flight Service Center of any kit excesses and/or changes required (see part 2, chapter 21).

6–3

6.12. AWP Procedures. Requests for bits and pieces to repair DIFM items are processed according to chapter 3, this part. Under most circumstances, the mark for field must have a DIFM or an EAID detail document number. An AWP monitor should be appointed in each maintenance activity to act as liaison with Logistics Readiness Squadron/supply activity. Followup, update, and cancellation actions must be coordinated between the Flight Service Center and the Maintenance work center.

NOTES:

1. When the first AWP due-out is set up, the code on the end-item DIFM will be changed to AWP under program control. When the second AWP due-out is set up, the code will be changed from AWP to 02P. Further processing increases the status code counter, that is, sequential processing will result in code assignment AWP, 02P, 03P, 04P, etc....03P, 02P, AWP, FWP.

2. DWO should be assigned to UJC AR/BR requirements when the asset must be retained on the end-item or system.

3. Status code FEM is assigned when the issue request UJC is AU, BU, or CU, and the delivery des-tination field is FEM.

4. When the last AWP due-out is released or canceled, the code on the end-item DIFM detail will be changed to FWP under program control.

5. Status code VHM can only be applied by vehicle maintenance organizations.
