NAVSUP Weapon Systems Support Philadelphia intends to solicit on a sole-source basis with Sikorsky for repair of one control panel (NSN 1680-016934654, P/N 06600-00813-103) for the H-53K platform, FOB origin. No drawings or data are available, and the Government does not own the data or rights needed to source this part elsewhere. Award is expected under an existing Basic Ordering Agreement. Unapproved firms must submit a Source Approval Request, but the procurement will not be delayed for SAR approval. Electronic procedures will be used via NECO, and interested organizations may submit capabilities and qualifications by email; no telephone requests or hard copies will be honored.
