At present there are approximately 230 How-Mal AFM 66-1 code words used to describe equipment failures occurring in Air Force equipment. Some of these code words are very similar in meaning. Unnecessary time spent by the technician searching through the list of code words for the appropriate code can be avoided if the number of code words is minimized by eliminating or consolidating those which, as used, are redundant. The study corroborates by multi-dimensional scaling methods groups of redundant How-Mal code words previously identified by factor analytic methods.
