This study focuses on the aircraft avionic maintenance problems of cannot duplicate CND and retest-ok RTOK for three sampled F-16 wings. Analytical and survey methods are used to evaluate four hypothesis in an attempt to determine causes of CND and RTOK occurrences and evaluate if they point to usable solutions to these problems. Hypothesis one evaluates the statistical differences in CND and RTOK rates between the sampled wings. Hypothesis two compares RTOK rates between avionic intermediate maintenance AIS test stations. Hypothesis three compiles the frequency of CND occurrences for each aircraft to determine if some aircraft experience higher CND rates than others. Hypothesis four evaluates the number of days between CND or RTOK corrective actions and the next maintenance repair action. The RTOK rates evaluated in hypothesis one were significantly different and require further study. Test stations RTOK rates for hypothesis two were significantly different between test stations, and between wings, and requires further study. Results for hypothesis three indicate some aircraft, given to chance, will experience higher cnd andor RTOK rates than others. The results of hypothesis four imply that 50 percent of all aircraft malfunctions cleared as CND or RTOK require maintenance repairs. Author
