Description: The purpose of this thesis is to explore potential challenges facing the implementation of an Isochronal Scheduled Inspection System (ISIS) for the United States Navy's P-3 Orion. Implementation of ISIS, which is based solely upon calendar time, has been proposed to replace the present system of scheduled inspections that are based upon both calendar time and flight hours. The United States Customs Service and the Royal Netherlands Navy have successfully fielded the ISIS program and demonstrated that the concept works when implemented on a small scale. It is not known however, how well the program might work when applied to a larger organization. This thesis obtains insights into potential troubles arising from implementation of the ISIS program by building and analyzing a simulation model. The model's output includes the number of  times that changes must be applied to the planned schedule, the number of days aircraft are prematurely worked upon, and the number of days aircraft are delayed awaiting maintenance. The analysis provides a measure with which to gauge the difficulty of implementing the ISIS program in the U.S. Navy.
