C47B engine turbine and compressor repairs for TPR 3

The Michigan State Police (MSP), specifically the Special Operations Division's Aviation Unit, is seeking a Rolls Royce Authorized Maintenance Center to perform a comprehensive 2000-hour engine overhaul for the Trooper 3 aircraft (N383ST), identified as a C47B engine turbine and compressor repair project. The Request for Proposal (RFP) requires a detailed restoration process involving replacement of multiple turbine wheel stages, comprehensive inspections, and test cell runs. The solicitation was released on July 10, 2025, with proposal submissions due by July 24, 2025, and an anticipated contract start date of August 1, 2025. The contract mandates completion of all overhaul activities within 90 business days of order receipt, with delivery specified to MSP Aviation in Lansing, Michigan. The evaluation process is structured as a pass/fail assessment, with mandatory minimum requirements including manufacturer authorization and strict compliance with Rolls Royce RR 250-C47B maintenance manual technical specifications. Bidders must provide comprehensive pricing schedules covering labor and parts for turbine, compressor, gearbox, and hydromechanical unit (HMU) components, with all applicable FAA documentation required to be tagged to overhauled components.

The procurement explicitly restricts participation to Rolls Royce Authorized Maintenance Centers, with no subcontractors permitted. While specific set-aside designations for disadvantaged enterprises are not detailed in the documentation, the procurement appears to have stringent technical qualifications that will significantly limit potential bidders. The State reserves the right to require additional warranties beyond those initially proposed by bidders, indicating a robust quality assurance approach. No incumbent vendor information or specific budget range was explicitly stated in the available documentation. The contract appears focused on highly specialized aircraft engine maintenance services, requiring precise technical expertise and manufacturer-specific authorization. Delivery is specified to the MSP Aviation location in Lansing, Michigan, which suggests a localized, targeted procurement process for critical aviation maintenance services. The comprehensive nature of the RFP, with its detailed technical requirements and strict manufacturer authorization criteria, indicates a high-value, mission-critical maintenance contract for the Michigan State Police Aviation Unit.
