The Department of Defense, through the Naval Air Systems Command (NAVAIR), intends to award an Indefinite Delivery Indefinite Quantity (IDIQ) contract for sealant removal and replacement services on E-6B aircraft. The contract will specifically involve the removal of EF-5992 sealant and its reapplication on fuel cells and surfaces of nine E-6B aircraft, with performance expected at Tinker Air Force Base in Oklahoma during depot maintenance events from Fiscal Year 2025 through 2029, including options for two additional years. This procurement is critical as it ensures the integrity and safety of the aircraft, with Performance Aircraft Systems, Inc. being the sole source due to their unique capability to perform the work without damaging the aircraft structures. Interested parties may submit capability statements within 30 days of this notice, and for further inquiries, they can contact Randy Putnam at randolph.a.putnam.civ@us.navy.mil or Lisa Troccoli at lisa.j.troccoli.civ@us.navy.mil.
