This report presents the results of a study of current diagnostic techniques and procedures used at the aviation unit maintenance level for Army helicopters. A projection is provided to show the potential improvement which could be attained in reliability R, availability A, and direct support costs C for selected helicopter components through improved diagnostic methods. This potential would be realized if the current field diagnostic capability were improved to the effectiveness represented by the engineering teardown underlying the Disassembly and Inspection Reports DIRs. The validity of current diagnostic monitoring devices, techniques and procedures is presented in terms of comparison of the unit removal reason to the actual DIR finding upon teardown. A relationship of primary fault indicators to the degree of aircraft damage or loss of mission effectiveness is also presented. Author
