The Navy intends to award a sole source contract to ACE Aeronautics LLC for the repair of 20 attitude indicator units for C130 aircraft, as they are the original equipment manufacturer and only known source. No technical data or drawings are available, and firms not already approved must submit a Source Approval Request, though the procurement will not be delayed for approval. The contract will have a one-year duration, and delivery will be FOB origin. Interested responsible sources may submit a capability statement to the contracting officer for consideration.
