An Analysis of the Standard Depot Level Maintenance (SDLM) Program of the F-14 Tomcat

Since 1991, the cost and schedule of the F-14 Tomcat Standard Depot Level Maintenance (SDLM) Program has doubled. Additionally, the requirements for In-Service Repair (ISR) have grown at a exponential rate as SDLM deferrals from the Aircraft Service Period Adjustment (ASPA) Program have caused the m...

Description
Summary:Since 1991, the cost and schedule of the F-14 Tomcat Standard Depot Level Maintenance (SDLM) Program has doubled. Additionally, the requirements for In-Service Repair (ISR) have grown at a exponential rate as SDLM deferrals from the Aircraft Service Period Adjustment (ASPA) Program have caused the material condition of the aircraft to deteriorate and the need for depot-level field team rework to become increasingly demanded. As the cost of SDLM and ISR have grown, the number of aircraft overhauled each year has decreased. Recent efforts to decrease the scope of the SDLM Specification, or work breakdown, have not reduced this trend. The 1996 Preliminary SDLM Specification further reduces the depot's requirements placing more work into the hands of organizational level sailors, without compensating these units with additional manpower. This cycle will continue and the cost for SDLM and the need for ISR will grow to the point where the aircraft will no longer be cost effective. In the meantime, our organizational units will continue to strive to maintain the aircraft to an acceptable level while additional workload is placed on them taking advantage of free sailor labor. This research shows that the present course will lead the aircraft to a cost effectiveness termination far short of the 2010 goal, while placing an undo burden on our organizational units.
