The U.S. Air Force requires depot-level remanufacturing services for the C-5 Main Landing Gear Trunnion Bearing to support yearly demand for field-level and depot maintenance. This is a market survey to identify potential sources with the expertise and capability for qualification and production, not a solicitation. The government encourages responses from both large and small businesses, as well as teaming arrangements, and has not yet determined a set-aside status. No specific budget, performance location, or project timelines are provided in this initial survey phase.
