This is a market research notice seeking potential sources to supply specific critical safety components for the TH-1H helicopter. The items are commercial, off-the-shelf parts, and the government's analysis indicates Bell Textron Inc. is the only known manufacturer with the legal proprietary authority and technical data to produce them. The government will consider competition if other qualified sources with the required legal authorization and technical capabilities identify themselves. Interested parties must respond by 6-APR-2026 to the specified government email contacts. If no additional sources are identified, the government intends to award a non-competitive contract to the sole source.
