This requirement is for the procurement of spare parts. The government prefers and will accept early and incremental deliveries. No specific performance location, budget amounts, or non-bid/proposal timelines are detailed in the provided description.

This is a specialized procurement for two flight-critical parts that requires government source approval prior to contract award. The Government intends to solicit and negotiate with only one pre-approved source under FAR 6.302-1. While this is a notice of intent and not a formal competitive request, all proposals received within 45 days of the synopsis publication will be considered. An alternate source must qualify through the design control activity's procedures, but the approval timeline is normally too long to delay an award. Interested parties who are not approved sources must submit specific source approval information with their proposal.
