This file contains Sections L and M of a Request for Proposal for the production of the 20MM Mechanical Housing (NSN 1005-01-190-9802, P/N 209F953), issued by the Defense Logistics Agency Aviation. The Transfer Unit Mechanical Housing is a gear-driven component attached to the M61A1 gun that transfers live ammunition rounds from the feed chute to the feeder assembly and returns expended cases from the gun breech bolts to the return chute. The acquisition strategy designates this item suitable for competitive acquisition for the first time under Acquisition Method Code 2/C; however, due to existing unique design capabilities, engineering skills, and proprietary manufacturing knowledge retained by qualified sources, acquisition is restricted to approved sources. Alternate sources must qualify according to the design control activity's established procedures and receive approval from the cognizant Government engineering activity. The part requires engineering source approval to maintain quality standards, and alternate qualification procedures must be approved by the Government engineering activity having jurisdiction over the part's intended application.
