The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking to procure six rotary wing blades on a sole source basis. The specific item required is identified by NSN 7R 1615-011589679 and part number 70150-29100-041, which is classified as a Critical Safety Item, necessitating Government Source Approval prior to award. This procurement is crucial for maintaining operational readiness and safety in military aviation, as the government lacks sufficient data to contract with sources other than the current supplier. Interested vendors must contact Dana Scott at dana.l.scott14.civ@us.navy.mil for further details and must comply with the requirements outlined in the NAVSUP WSS Source Approval Brochure to be considered for the contract.
