As you have already discovered, there is much more to being an LPO or LCPO than just telling people what to do. As you advance, you become more knowledgeable about the way your command operates on a daily basis. You also become more involved in the administrative aspects of the management process. This process, of course, goes far beyond 3-M reporting or logging daily magazine temperatures. In this chapter we will acquaint you with some of the more important administrative procedures you may become involved with as a senior Gunner's Mate.

CORRECTIVE MAINTENANCE MANAGEMENT

LEARNING OBJECTIVES: Describe the cause and effect of corrective maintenance.

Many people operate under the philosophy "If it's broke-fix it; if it works-leave it alone." However, this attitude defeats the purpose of discrepancy trend analysis. In other words, you should closely monitor the documented histories of your equipment. You should then be able to predict potential problems or breakdowns based upon your knowledge and familiarity of that equipment. This practice could enable you to spot recurring equipment tendencies and prevent discrepancies before they occur. You are then accomplishing the purpose of performing preventive maintenance.

CURRENT SHIP'S MAINTENANCE PROJECT

One of the best aids in identifying material discrepancy trends is through the use of the Current Ship's Maintenance Project (CSMP). All levels of management can use the CSMP. The work center supervisor, up through the type commander, can use it for such purposes as operational scheduling, overhaul work packages, and availabilities. Above all, they can use it as a means of identifying trouble areas within a particular unit, system, or even component. We will not show you how to maintain a CSMP;, you should already know how to do that. A properly maintained historical record of the equipment you are responsible for may prove to be a highly invaluable tool in its upkeep.

3-M SYSTEMS' CENTRAL DATA BANK

Did you ever wonder where all that data you submit on an OPNAV 4790.2K ends up? One important destination for this information is the 3-M Systems' Central Data Bank located in Mechanicsburg, Pennsylvania. The Naval Maintenance Support Office (NAMSO), which is a subordinate department of the Naval Sea Logistics Center (NAVSEALOGCEN), maintains this data bank. Fleet personnel submit MDS reports, such as work requests, deferrals, configuration changes, and failed-parts reports. They are then entered into this data bank. This data is then made available to whomever requests the information. This bank is the source of most of the 3-M reports that are sent to ships, other levels of naval management, and authorized defense contractors. However, these reports are also available to any requesting naval activity. Figure 13-1 shows a completed request form used to obtain 3-M reports from the central data bank. Detailed instructions on how to fill out this request form, as well as a summary and explanation of what reports are available, are located in chapter 4 of the Ships' 3-M Manual, OPNAVINST 4790.4.

SYSTEM LOGS AND RECORDS

Another important tool in heading off equipment problems before they happen is through the review of the various system logs and records. It is impractical to list them here because they are covered in some detail in other training manuals. Instead, two examples are provided here to show how a log or record may aid in the trend analysis process.

While performing bore erosion checks, you notice what you consider an unusual amount of erosion. In checking the fire control smooth log, you verify that this is true-you have more than the usual amount of bore erosion for a given time period and a given amount of rounds fired through the gun. At this point, you may

decide that the gun needs to be rebarreled at an earlier date than may have already been planned.

You are reviewing magazine temperature records and discover that the forward magazine consistently has a 2 higher daily temperature reading than the after magazine. Is the forward magazine getting warmer than the after magazine? Is one of the magazine thermometers out of proper calibration? These are some of the factors that should be examined and acted upon.

As you can see, your system logs can provide valuable insight into any number of equipment deficiencies or tendencies. Always try to maintain accurate records and logs.
