If the SDLM is deferred, the expenditure of depot funds for an aircraft is deferred in the current year. Initially, the program allowed for the extension and deferral of numerous aircraft and did produce a one time saving. However, it has been observed that deferring SDLM, results in the deterioration in aircraft material condition. More over, ASPA brings significant uncertainty in depot parts support and SDLM planning and scheduling. ASPA causes a redundancy of effort in duplicating the aircraft inspections for ASPA and for induction into SDLM. In this research we show that the termination of the ASPA Program will significantly reduce the uncertainty and variability inherent in the Navy depot induction process. With the variability reduced turnaround time, organizational and depot workload, man hours expended and total costs
