The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of a Shut Off Valve, AIRC, under a sole source requirement. The procurement involves specialized repair services that must adhere to strict quality and inspection standards, as the government lacks sufficient data to contract with other sources. This valve is critical for aircraft operations, and the contractor will be responsible for ensuring that all repairs return the item to a Ready for Issue (RFI) condition. Interested parties should contact Alexis Healy at 215-697-1143 or via email at alexis.healy@navy.mil for further details, and proposals must remain valid for a minimum of 120 days following submission.
