The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of spare parts under the title "16--RETAINER." This procurement is a sole source requirement, focusing on new manufacture spare parts that must be FAA-certified and accompanied by an FAA Authorized Release Certificate, as the government lacks sufficient data to contract with other sources. The selected contractor will be required to maintain a quality system compliant with ISO standards and must adhere to strict inspection and acceptance criteria throughout the contract's duration. Interested parties should direct inquiries to Danielle Junod at danielle.m.junod.civ@us.navy.mil, with proposals remaining valid for a minimum of 120 days following submission.
