Reference symbols are found in the IPB for the component. RELIABILITY —The probability that an item will perform its intended function for a specified interval under stated conditions. REPAIR—Necessary preparation, fault correction, disassembly, inspection, replacement of parts, adjustment, reassembly, calibration, or tests accomplished in restoring items to serviceable status. REPAIR CYCLE DATA—An uninterrupted record of a repairable item from the time of removal until repair is completed or a reclamation or salvage determination is made. Material capable of separate supply and replacement that is required for the maintenance, overhaul, or the repair of an end article; for example, airframe, accessories, in- struments, engine, propeller, electrical, electronics, photographic, armament, and training equipment, including the repair parts of SE. This definition does not include the SE end items. REPAIRABLE ITEM—A durable item which, when unserviceable, can be economically restored to a serviceable condition through regular repair procedures. REPLACEMENT ITEM—An item that is func- tionally interchangeable with another item but differs physically from the original in that the installation of the replacement requires operations such as drilling, reaming, cutting, filming, or shimming, in addition to the normal application and methods of attachment. REPORTING CUSTODIAN—An organizational unit of the lowest echelon of command accepting responsibility, involving the accountability to the CNO, for aircraft or engines, as designated either by CNO or by the aircraft controlling custodian. NOTE: Each aircraft or engine at any given time from acceptance to strike is in the reporting custody of one, and only one, reporting custodian. REPORTING CUSTODY—Responsibility to account for and provide information about assigned aircraft or SE. This does not necessarily imply physical custody. REPORTING PERIOD—For the purpose of the MDS, a reporting period is 1 month. RETIREMENT—Separation of aircraft from the program inventory. Separation may be accomplished by (1) strike, (2) transfer to status codes series P, R, 5, and Y, or (3) transfer to a contingency reserve status (code series W). RETROFIT—Incorporation of an engineering change, at any level, in accepted or in-service items. REWORK—The restorative or additive work performed on aircraft, aircraft equipment, and aircraft SE at NAVAVNDEPOTs, contractors’ plants, and such other industrial establishments designated by TYCOMs. A rework process extends from the time some of the work is started until all of the work has been completed, including temporary interruptions in direct labor; it also includes rework evaluation and test and correction of discrepancies determined thereby. Rework is divided into two categories: standard and special. RFI—Ready for Issue. RFI MATERIAL—Ready-for-Issue  Material— Material, equipment, aircraft, and SE which does not require rework of any type, replacement of overage parts, or other than routine preinstallation and post installation condition verification prior to use. RMKS —Remarks (message). SA/A —Systems Administrator/Analyst. SAFETY/EI SER—Safety/Engineering Investigation Serial Number—A locally assigned four-digit safety EI serial number. SALTS—Streamlined Automated Logistics Transmis- sion System. SCC—Sequence Control Card. SCIR—Subsystem Capability and Impact Report- ing. SCT—Special Crew Time. SDLM—Standard Depot-Level Maintenance. SE —Support Equipment. SEAOPDET —Sea Operational Detachment—A sea duty component assigned to shore IMAs that is used to augment the aircraft carrier’s IMA in support of carrier air wing embarkations. SEATS—Survival Equipment Asset Tracking Sys- tem—SEATS is a database management system AI-22
