The U.S. Air Force is conducting market research to identify sources capable of designing, integrating, and testing a rotor brake for the MH-139A helicopter, leveraging the commercial baseline system from the Leonardo AW139. The objective is to enhance ground safety and operational efficiency, particularly in high-wind environments, through standardized installation across the fleet. No specific budget amount is provided, and this is a Request for Information (RFI) only, not a solicitation. Performance of services will occur at a Government-designated facility for fit-checks, with technical support expected during and after initial implementation. Respondents must submit comprehensive responses addressing technical capability, cost estimates, and timelines, with no submission deadline specified.
