This is a sole-source procurement notice for one Escape Hatch Assembly intended for Sikorsky under an existing Basic Ordering Agreement. The government does not own the technical data needed to purchase this part from other sources. While considered a sole source, proposals from other responsible sources received within 45 days of the synopsis will be considered for the purpose of potentially conducting a future competitive procurement. Any firm not already approved to manufacture this item must submit a Source Approval Request, but the procurement will not be delayed for its approval. Electronic procedures will be used, and capabilities/qualifications must be submitted via a specified email address.
