How to bid on various gearboxes for the US Coast Guard

What the Coast Guard is buying and why it matters

The US Coast Guard is seeking a vendor to supply various new gearboxes, including a specific main gearbox (NSN: 1615-01-675-1816, PN: 7035138100-052). This will be a three-year Indefinite Delivery Requirements (IDR) contract with firm-fixed pricing (FFP), consisting of a one-year base period and two one-year option periods. This opportunity is significant for firms that can provide these specialized parts, especially those with direct ties to the Original Equipment Manufacturer (OEM).

The Coast Guard emphasizes that all parts must be new, approved, and have clear traceability to the OEM, Sikorsky Aircraft Corporation (Cage Code 78286). This is a sole-source procurement, meaning the government intends to buy only from Sikorsky or sources with clear traceability to Sikorsky as the OEM. The parts must also be approved in accordance with Federal Aviation Administration (FAA) guidelines to ensure aircrew safety.

The solicitation was published on March 09, 2026. All proposals are due by September 30, 2026, at 2:00 PM Eastern Daylight Time (EDT). This is a firm deadline; proposals received after this time will likely not be considered. The contract duration will not exceed three years.

Who this opportunity suits

Vendors must be able to provide a Certificate of Conformance (COC) in accordance with FAR clause 52.246-15, and a certificate of airworthiness (FAA 8130 preferred) or equivalent EASA Certification, or a certificate of conformance and traceability to the OEM for newly manufactured commercial items.

Practical tips for a competitive response

Given this is a sole-source procurement with strict traceability requirements, your proposal must clearly demonstrate your connection to Sikorsky Aircraft Corporation as the OEM. Provide a detailed, documented, and auditable paper trail for each part, tracing it from the OEM to its current location. Emphasize your ability to meet the FAA guidelines for airworthiness and safety.

Ensure your Certificate of Conformance (COC) is submitted in the exact format specified in FAR clause 52.246-15. For newly manufactured commercial items, include either an FAA 8130 or equivalent EASA Certification, or a certificate of conformance with clear traceability to the OEM.
