Pratt & Whitney Canada (P&WC) PT6C-67C turboshaft engine Maintenance

The United States Air Force Life Cycle Management Center (AFLCMC) is conducting market research to identify possible sources capable of providing inspection, overhaul, repair, and upgrade services for three government-provided Pratt & Whitney Canada (P&WC) PT6C-67C turboshaft engines. The goal is to upgrade and return these engines to airworthy status for use as spares in the MH-139A fleet. The required services include inspecting, overhauling, and repairing the engines, as well as upgrading them to the PT6C-67C1 configuration and maintaining and/or obtaining FAA certification. • The MH-139A aircraft provides vertical lift support for nuclear weapon convoy escort and 24/7 adverse-weather-capable Intercontinental Ballistic Missile (ICBM) emergency security and operational support. • The MH-139A fleet has been upgraded to the PT6C-67C1 engine configuration to enhance military use. • Respondents are asked to provide information on their experience in overhauling and upgrading P&WC PT6C series engines, facility capabilities, and proposed approach to inspecting, overhauling, repairing, and upgrading the PT6C-67C engines. • Respondents are also asked to provide a rough cost estimate for both inspection, overhaul, and repair, and upgrade of the engines to the PT6C-67C1 configuration and obtain FAA certification.
