RELIABILITY OF SELECTED HOW-MAL CODE CLUSTERS: B-58 SYSTEM.
Abstract
The purpose of this study was to identify groups of How-Mal (AFM 66-1) codes which are redundant, i.e., are equivalent within a group. The frequencies of use of the 35 most frequently used How-Mal codes over 4 types of maintenance actions and 203 subassemblies of the B-58 were analyzed statistically. A principal-axis factor analysis revealed 14 groups of codes, 3 of which were found in a previous study. Twenty of the codes accounted for 95% of the 12,041 malfunctions reported. The frequencies of appearance of the codes were correlated r = 0.76 with their appearance in an earlier study. Several How-Mal codes are recommended for rejection from the list of allowable codes.
