Piedmont Propulsion Systems, LLC

Piedmont Propulsion Systems, LLC, a small business subsidiary of First Aviation Services Inc., provides propeller maintenance, repair, overhaul, and rotor hub services to federal agencies as a prime contractor on 135 awards (86% of recent work) and as a subcontractor on 22 awards. The company competes under Total Small Business set-asides on roughly half its prime work and full-and-open on the remainder; recent set-aside designations include a $1.54 million NOAA single-award Indefinite Delivery Contract for Hartzell propeller full-service maintenance (awarded June 2024, running through June 2029) and an $818,943 single-award IDC with the National Interagency Fire Center for propeller overhaul and parts (awarded February 2023, running through January 2028). Piedmont is based in Winston-Salem, North Carolina, where all facility-named work is performed.

Customer concentration skews heavily toward the Department of Homeland Security U.S. Coast Guard, which accounts for 105 awards (90% coverage by award count) and $8 million in combined potential value—predominantly small firm-fixed-price purchase orders under Coast Guard Indefinite Delivery Contract HSCG3816DL00007 (72 task orders, $3.8 million combined potential value) for repair of HC-144 aircraft components including actuator assemblies, bulkheads, rings, and propeller blades. The Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command ranks first by potential value, with 3 awards totaling $13.3 million, anchored by a $11.5 million five-year IDIQ awarded August 2022 (running through August 2027) for maintenance and overhaul of UH-60 helicopter rotor hubs, against which two delivery orders have been placed ($1.135 million in August 2022 and $592,434 in September 2023). The National Oceanic and Atmospheric Administration follows with 15 awards valued at $2.9 million, including the June 2024 Hartzell propeller single-award IDC and six task orders under NOAA's broader AOC full-service maintenance framework for inspection, overhaul, and repair of propellers on DHC-6 Twin Otter and King Air aircraft. The National Interagency Fire Center and Department of Transportation Federal Aviation Administration round out the top five by dollars.

Award activity has grown sharply—from 4 prime awards in 2022 to 11 in 2023, 11 in 2024, and 21 in 2025—with only one award (combined potential value $592 thousand) reaching ultimate completion within the next twenty-four months, presenting minimal recompete cliff exposure near term. Piedmont's capability footprint is narrowly concentrated in propeller and rotor hub maintenance under NAICS 238390 (Other Support Activities for Air Transportation) and 332914 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), with 127 and 18 awards respectively; PSC-level concentration runs to mechanical power transmission equipment maintenance and repair (73 awards), aircraft component and accessory maintenance (31 awards), and aircraft propeller components (16 awards). Representative prime work includes the $1.135 million Army delivery order for UH-60 rotor hub maintenance (September 2023), a $68,057.93 NOAA delivery order for inspection and overhaul of two Hartzell HC-B3TN-3DY propellers on a DHC-6-300 Twin Otter (February 2025), and multiple Coast Guard purchase orders for HC-144 component repair ranging from $3,100 to $192,836.

On the subcontractor side, Piedmont delivers propeller repair and aircraft parts support to Sierra Nevada Company (nine BIG SAFARI awards from September 2025 through October 2025 for propeller and aircraft parts work), AAR Government Services (five Worldwide Aviation Support Services awards from January 2025 through June 2025 for propeller repair), and JPATS Logistics Services (five Contractor Operated and Maintained Base Supply (COMBS III) awards from January 2025 through May 2025 for propeller assembly supply). The parent company First Aviation Services Inc. carries a subsidiary, Saint Technologies Inc., identified as a manufacturer of goods; no distinct capability or award framing for the subsidiary is provided in the source.
