The Government is conducting market research to identify potential sources capable of manufacturing/procuring the Linear Actuating Cylinder Assembly (NSN 1650-01-187-9395HL; P/N 205-076-056-107) for the TH-1H helicopter. The item is an Aviation Critical Safety Item used in the TH-1H flight control system; only approved sources can meet the military requirement, the OEM is Woodward HRT, Inc. (CAGE 81873), and the TH-1H OEM is Bell Textron, Inc. (CAGE 97499). The Government does not own the required technical data, considers buying the data or reverse engineering the part uneconomical, and requires alternate sources to obtain engineering source approval through a Source Approval Request under AFMCI 23-113 from AFLCMC/WIHEZ and be prequalified before award. The anticipated strategy is a five-year Indefinite-Delivery Requirements-type contract (one-year basic plus four one-year ordering periods) continuing through FY33, with projected BEQs of 32 units in the basic year and 28–38 units in each outyear, and contractors must furnish all material, support equipment, tools, test equipment, and services. No set-aside decision has been made, and large and small businesses, joint ventures, and teaming arrangements are encouraged to participate in the market research and capability survey.
