DLA Aviation Philadelphia is seeking contractors to manufacture a specific shipping and storage part (NSN 66KH 8145 012865679 V2, P/N 434E001) used on the MV-22 aircraft. The Government intends to negotiate with only one or a limited number of sources and does not possess the data needed to manufacture the item. This is a sources sought notice, not a competitive solicitation, but proposals received within 5 days of the notice's publication may be considered. The item requires engineering source approval from the design activity, and new sources should contact the buyer to inquire about approval procedures. Performance will be for DLA Aviation Philadelphia.
