This study investigated the change in Type IV PMEL workload requirement resulting from the implementation of the two-level maintenance 2LM concept. Seven Type IV PMELs were studied and the information was used to profile a typical Type IV PMEL. The researcher was able to predict the total inventory owned by the Type IV PMELs customers, the number of items supported by the Type IV PMEL, and the percent of the Type IV PMEL workload affected by 2LM. All these values were determined by using inferential statistics and were expressed in terms of confidence intervals. The researcher also examined the first six months of production data recorded while operating in the 2LM concept. ANOVA and t tests were used to test the hypothesis that the mean variety of equipment, mean maintenance hours expended, and mean AIS station utilization recorded were not significantly different from the mean values recorded for the same six month period the previous year, while operating in the three-level maintenance 3LM concept. The test results seem to indicate that implementing 2LM results in little or no difference in the Type IV PMEL workload.
