Reliability Enhancement & Reengining Program

Abstract

674835: C-5 Reliability Enhancement and Re-engining Program (RERP): RERP is a comprehensive modernization effort to improve aircraft reliability, maintainability, and availability. RERP will enable the C-5 to achieve wartime mission requirements by increasing fleet availability (mission capable rate, departure reliability). This effort centers around replacing the current TF39 engines with more reliable, Commercial Off-the-Shelf CF6 turbofan engines with increased take-off thrust and stage three noise compliance. The new engines increase payload capability and access to Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) airspace. The modification also decreases aircraft time to climb, increases engine-out climb gradient for takeoff, improves transportation system throughput, and decreases engine removals. Additionally, numerous other system modifications will be performed to increase fleet availability. Increased costs led to a review of total program requirements. On 14 Feb 08, USD (AT&L) certified a restructured RERP to Congress. This restructured program reduced RERP scope to include only 49 production aircraft (47 C-5Bs and 2 C-5Cs). The AF was directed to fully fund RERP to the OSD Cost Analysis Improvement Group (CAIG) Independent Cost Estimate (ICE). On March 14, 2008 USD AT&L conducted a successful Milestone C (MS C) Defense Acquisition Board (DAB). USD AT&L signed the Acquisition Program Baseline (APB) reflecting the N-M certification and the MS C approval on June 24, 2008. Equipment Diminishing Manufacturing Sources (DMS) issues will be resolved to support continued operations through studies, bridge buys, life of type buys, development and redesign efforts. This project is comprised of low technical risk efforts supporting fielded weapons systems and, therefore, was assigned to Budget Activity 7, Operational Systems Development. FY 2009: Funding supported RERP design, development, engineering change orders, and contractor/government test. Mission support funding is required for program office operations and second destination transportation costs. FY09 funding also supports initiation of development/delivery of aircrew/maintenance training devices to meet operational training requirements. FY2010: Funding supports RERP design, development, engineering change orders, and contractor/government test. Mission support funding is required for program office operations and second destination transportation costs. FY10 funding is also required to continue the development/delivery of aircrew/maintenance Training devices. FY2011: Funding supports RERP design, development, engineering change orders, contractor test, and final technical order publication. FY11 funding is also required to finalize the development/delivery of aircrew/maintenance training devices.
