About this opportunity
The United States Air Force Life Cycle Management Center (AFLCMC) is conducting market research to identify qualified contractors capable of providing comprehensive inspection, overhaul, repair, and upgrade services for three Pratt & Whitney Canada (P&WC) PT6C-67C turboshaft engines. The primary objective is to restore these government-provided engines to airworthy status and upgrade them to the PT6C-67C1 configuration for use as spare components in the MH-139A fleet, which provides critical vertical lift support for nuclear weapon convoy escort and 24/7 adverse-weather capable Intercontinental Ballistic Missile (ICBM) emergency security operations. Responses must demonstrate current technological capability and relevant qualifications, with submission requirements including company identification, CAGE code, point of contact information, and documentation of small business status and certifications per NAICS Code 488190. While specific evaluation criteria are not detailed in this pre-solicitation notice, respondents should emphasize their expertise in FAA certification maintenance and complex turboshaft engine restoration. The response deadline is January 15, 2026, providing interested parties approximately 3.5 months to prepare and submit their capability statements.
This pre-solicitation notice involves no set-aside designations, and no incumbent contractor is identified. The procurement encompasses three specific engines with varying service histories: engine PCE-KB0600 (971.8 hours), PCE-KB0711 (946.4 hours), and PCE-KB0466 (4,868 hours), with the highest-hour engine having accumulated 2,747 documented cycles. The engines have not been preserved since their last logbook entries in 2019 and have undergone various testing events including live fire and ingestion testing, which may require extensive remediation work. No specific award value or budget range is disclosed in this market research notice, indicating that cost estimates will depend on contractor proposals. The place of performance will be at the contractor's facility, and interested parties should prepare comprehensive responses documenting their qualifications for this specialized aerospace maintenance and upgrade work.
