Figure 3-9.–The format of the master repairable item list (MIUL), Parts 1 and 2. Why should the item(s) be turned in? Is there special material content? Is there hazardous material content? Is the item a depot level repairable? Mandatory turn-in repairable can be identified by the material control codes H, E, X, G, or O located in the third position of the item’s NSN. For the program to work as intended, you must return repairable items promptly and in repairable condition. At the time you present your request for a mandatory turn-in item, supply must inform you that the removed part must be returned. Therefore, when you receive the replacement you are required to do the following: Remove the defective item without damaging it beyond its already defective condition. Provide adequate protection to the item so it will not be further damaged before it is turned in to supply. The most effective way, if at all possible, is to place the defective part in the same container in which you received the replacement part. Resist the temptation to cannibalize the item for components that you might possibly use sometime in the future. Return the defective item to supply as soon as practical. Sometimes the needed replacement item is not in the storeroom; supply must obtain it. Normally, you should still turn in the failed item, even though you have not received the replacement item. This way the failed item can enter the repair cycle and be available for reissue soon. NOTE: The exception to this requirement is when equipment can still be used under limited operation with the failed part in place until the replacement is received. If this is the case, you MUST obtain a “Remain in Place” certification. You can find information about the packaging for protection in the technical manual of the equipment involved. You can also obtain additional information from the supply department at your command. They may suggest that you not package the turn-in item because of any inspections required before shipment or they may say their shipping personnel have the necessary materials to package the item properly. There are two references that you should know about if supply department personnel are not readily available to assist you. They are the Afloat Supply Procedures, NAVSUP Publication 485; and Supply Ashore, NAVSUP Publication 1. 3-15
