The Department of the Interior, through its Acquisition Services Directorate, intends to award a sole-source contract to Cub Crafters, Inc. for the procurement of a new Lycoming O-360-C1G engine, specifically required for a Top Cub aircraft. This engine is critical for the Office of Aviation Services' operational capabilities, and Cub Crafters is the only vendor able to deliver the engine within the necessary timeframe, as other manufacturers have lead times exceeding 18 months. The urgency of this procurement is underscored by the engine's FAA approval and its compliance with the existing Type Certificate, which are essential for maintaining efficient government aviation operations. Interested parties who believe they can meet these requirements must respond by December 23, 2024, at 2:00 p.m. EST, via email to the primary contacts provided: Maya Maxies-Clemons at maya_maxies-clemons@ibc.doi.gov and Stephen Klier at stephen_klier@ibc.doi.gov.
