AVSCOM has been collecting maintenance data via TAERS/TAMMS since 1964 and the files containing this data encompass millions of records. RAMMIT (Reliability and Maintainability Management Improvement Techniques) is a system designed to process maintenance data and other data relevant to the operations and support of Army aircraft. RAMMIT has been in development for approximately one year and management type information is being made available on a scheduled and as requested basis.Omissions and errors in reported data have been studied extensively and the determination made that if the data are properly processed, useful and reliable information can be provided. This report describes some of the methods used to identify and quantify these discrepancies so that valid values could be presented for each item's characteristics.The large volume of data input and the numerous types of data elements being reported has necessitated the development of a well organized series of reports. Therefore, brief descriptions of the various RAMMIT reports that are available, or will be available soon, are also presented in this report.Other features of RAMMIT reports and the design philosophies used in presenting the information are described. Illustrations and tables are provided as examples of the type of information that are included in RAMMIT reports. The basic objective of RAMMIT is to present experience data as management information and this report describes how this basic objective is being accomplished.
