The government does not own the technical data needed for manufacture, so interested firms must contact the OEM, Hamilton Sundstrand Corporation. The acquisition is not set aside for small businesses, and while the government intends to negotiate with a limited number of sources, all proposals received within 45 days of the synopsis publication will be considered. Performance will be evaluated on a combination of price and past performance.
