The Department of Defense, specifically the Department of the Air Force, is conducting market research to identify potential sources for the remanufacturing of the C-5 Landing Gear Right Angle Gearbox. The government intends to issue a sole source solicitation to Sargent Aerospace & Defense LLC, as they hold the proprietary data necessary for this remanufacturing process, which must comply with Technical Order 4S2-70-3. This gearbox is critical for the operational readiness of the C-5 aircraft, and the government is exploring whether this effort can be competitive or set aside for small businesses. Interested parties are encouraged to submit their company information and relevant experience to William Lee at william.lee.66@us.af.mil by the specified deadline, although no costs incurred in response will be reimbursed.
