This is a market research request to identify companies capable of manufacturing or obtaining specific spare parts currently sourced solely from Meggitt Aircraft Braking Systems (MABS), with the goal of potentially establishing a competitive long-term contract. The anticipated contract would have a 10-year total period of performance, consisting of a 5-year base period and a 5-year option. The government does not possess the technical data for these items, so companies must demonstrate their capability through a Source Approval Request (SAR) process. Interested parties must submit a response detailing their qualifications and experience by a specified deadline to be considered. This is not a solicitation, and the government is not obligated to issue a contract based on responses.
