About the company
Aircraft Propeller Service, LLC, a for-profit limited liability company based in Lake Zurich, Illinois, provides FAA-certified repair, overhaul, engineering, and parts services for aircraft propeller systems and associated components to the U.S. Coast Guard as a prime contractor, competing exclusively on unrestricted full-and-open solicitations with no set-aside usage across its prime footprint.
The company operates almost entirely as a Coast Guard prime contractor. Of seventy-five total awards spanning from 2009 through January 2026, seventy (96% of awards) went to the Department of Homeland Security's U.S. Coast Guard, with a combined potential value of $6.2 million. Two sub-awards to Amentum Services, Inc., awarded in May 2025 for aircraft maintenance and logistics support services involving blade-pin assemblies, represent the only subcontract exposure in the source data. The company holds one IDV with the Coast Guard — a multiple-award Indefinite Delivery Contract for overhaul and repair of 14RF-37 propeller assemblies and components, valued at $44,247.02 with an ultimate completion date of May 4, 2023 (since expired), under which two task orders were placed.
Aircraft Propeller Service's capability profile centers on HC-144 maritime patrol aircraft propeller sustainment. Representative prime work includes a $344,457.94 firm-fixed-price purchase order (June 2022) for repair and overhaul of propeller blades; a $299,958.59 purchase order (January 2023) for overhaul and repair of blades, hubs, and associated components; a $252,017.45 purchase order (March 2022) for HC-144 propeller blade overhauls; a $212,307.97 purchase order (January 2024) for blade repairs; and a $193,107.00 purchase order (February 2024) for delivery of propeller hubs. Recent 2024–2026 awards show smaller transactional values ranging from $7,184 to $139,596 per order, reflecting routine component-level repairs and procurements. Work spans teardown, test, evaluation, repair, overhaul, engineering investigation, and OEM-certified parts procurement, all performed to Hamilton Sundstrand and Airbus Defence and Space Original Equipment Manufacturer specifications at the contractor's FAA-certified facility. Coast Guard Aviation Logistics Center in Elizabeth City, North Carolina receives deliveries with Certificates of Conformance and FAA airworthiness releases.
Activity trajectory shows a peak in 2022 with sixteen awards, declining to five or six per year in 2023–2025, with one award recorded in 2026. The combined potential value of $6.2 million has been fully obligated (obligated dollars exceed potential value at 103%), indicating mature, lower-dollar task-order execution typical of routine aviation maintenance sustainment contracting. No recompete cliff data is present in the source, though the primary IDV with the Coast Guard (the 14RF-37 propeller assembly contract) completed in May 2023. The company's customer base is concentrated with the Coast Guard; the source names no other active federal customers beyond a marginal Customs and Border Protection relationship (two awards, value not separately broken out). Work is performed entirely at Aircraft Propeller Service's Lake Zurich facility as an OEM-authorized repair station and original equipment manufacturer-approved vendor, with no visible geographic dispersion or subordinate facilities in the award descriptions.
