Diesel Engine Replacement

The 633d Contracting Squadron at Langley Air Force Base, Virginia, is soliciting a single Hatz Diesel Engine, Model 4H50TIC, as a direct replacement for a failed unit in a Pressurized Cabin Leakage Tester used to support F-22 fighter aircraft maintenance. This procurement is structured as a combined synopsis and solicitation with a total small business set-aside under NAICS code 333618, limiting eligibility to small businesses as defined by the SBA. The engine must be an exact like-for-like match to the original, with confirmed specifications including a 4-cylinder configuration, 3432cc displacement, anticlockwise rotation, and a weight of 316.336 kg, and must correspond to the serial number 0801895003928 to ensure compatibility with existing control panel components that will be retained. Delivery of the engine is required by no later than May 15, 2026, to 160 E Danforth Ave, Langley AFB, Virginia, with performance and inspection expected to occur at this location. The solicitation does not specify pricing details, FOB terms, packaging standards, preservation methods, or labeling formats, but requires full compliance with all technical requirements outlined in the Statement of Requirement. Proposals must be submitted by May 8, 2026, and are governed by a simplified acquisition procedure. Contractors must comply with strict DoD access protocols, including obtaining installation passes, submitting workforce lists within 30 days of award, and adhering to operational security policies as defined by the Critical Information and Indicators List. All mishaps involving government property or personnel must be reported within 24 hours. The contract includes no options, no subcontracting provisions, and no explicit evaluation factors, but the nature of the requirement—technical precision with no deviation allowed—strongly suggests an LPTA approach. No formal FAR clauses, inspection criteria, or accounting data are included in the provided documentation, though the contracting office and maintenance squadron serve as the primary administrative points of contact for delivery and coordination.
