Sources Sought Notice for Re-Engining Options for HC-144B Aircraft.

The U.S. Coast Guard is seeking information from sources who can provide technical, cost, and schedule information for potential HC-144B Non-Developmental Item (NDI) aircraft engine systems retrofit solutions. The goal is to identify viable alternative propulsion solutions that can improve engine reliability, maintainability, and lifecycle cost while maintaining or enhancing performance in all mission areas. Respondents should provide information on their proposed engine/propeller solution, performance comparison to the baseline, status of any certifications or prior similar installations, and rough order of magnitude costs and installation schedule. * The HC-144B aircraft operates in a maritime environment and requires frequent operation at lower altitudes. * The proposed engine/propeller solution should minimize aircraft downtime and required airframe/system modifications. * The solution should comply with prevailing airworthiness standards (FAA FAR 25, EASA CS-25, or U.S. military equivalent). * The Coast Guard is seeking information to develop a strategy to maximize operational effectiveness and minimize total ownership cost of the HC-144B fleet.
