The Department of Defense, through the Defense Logistics Agency, is seeking to procure a sole source long-term contract for the Housing Assembly applicable to the CH-47 Chinook Helicopter Weapon System. The procurement involves a one-time buy of 20 units of the Housing Assembly, with a National Stock Number (NSN) of 1620-01-335-2695 and a part number of 414L2332-5, which is restricted to The Boeing Company due to the proprietary nature of the technical data. This acquisition is critical for maintaining the operational readiness of the Chinook helicopter, and the production lead time is set at 540 days with First Article Testing or 360 days without it, with deliveries to Tinker Air Force Base in Oklahoma. Interested parties should direct their inquiries to Lesley Odom at lesley.odom@dla.mil or Phanicia Montgomery at PHANICIA.MONTGOMERY@DLA.MIL, and must meet prequalification requirements to be eligible for award.
