Duncan Aviation Inc.

Duncan Aviation Inc., a large privately owned aircraft maintenance, repair, and overhaul provider headquartered in Lincoln, Nebraska, operates as a prime contractor on full-and-open federal contracts, delivering aviation turbine fuel procurement and specialized aircraft component repair services to the Department of Defense and related agencies. The company competes without set-aside designations and carries a Subchapter S Corporation structure with registration in SAM.gov dating to September 2001.

Duncan Aviation's federal award footprint is heavily concentrated in aviation fuel logistics. The top five customer agencies by award count account for 95% of recent awards, dominated by the Defense Logistics Agency Energy (3,047 awards, $25 million combined potential value), followed by the U.S. Coast Guard (92 awards, $1.3 million), Naval Air Systems Command (57 awards, $11.5 million), and the Air Force Sustainment Center (57 awards, $2.3 million). By dollar value, DLA Energy and Naval Air Systems Command anchor the portfolio—together representing most of the $87.5 million in combined potential value—while the Federal Aviation Administration (13 to 14 awards across two offices, $8.4 million combined) and the Air Force Sustainment Center round out the top tier. The customer concentration signal is striking: DLA Energy's 3,047 fuel-procurement task orders dwarf all other work; this is a vendor whose federal business is operationally fuel supply, not maintenance or repair diversity despite the company's core capability.

Duncan Aviation holds two significant indefinite delivery contracts. The primary vehicle is DLA Energy's contract SPE60017D0008 (1,746 task orders, $4 million combined potential value), a single-award IDC valued at $5,144,212.42 covering aviation jet fuel (Jet A) with and without fuel system icing inhibitor at commercial airports in the central United States, running through September 30, 2028. The second is a single-award IDC with the Air Force Sustainment Center (SPE60725D0058, 412 task orders, $672 thousand potential value) valued at $86,818 for repair of ATD-150 Controller Display Units on UH-1N helicopters through August 2029. Additional named IDCs include SP060012D0034 (885 task orders, $4.6 million potential value) and N0001906D0018 (55 task orders, $8.2 million potential value), placing Duncan Aviation on multiple government-wide fuel and logistics vehicles. Representative prime work includes a $1.3 million purchase order (September 2025) for TLC inspections and landing gear restoration of fixed-wing aircraft in Springfield, Michigan; a $72,000 transducer assembly purchase order from Naval Supply Systems Command (October 2025); servo unit repairs for the Air Force Sustainment Center ($7,975 and $8,443 delivery orders, March and October 2025); and navigation control repairs on TH-1H helicopters ($29,500, January 2026).

Activity trajectory shows sharp growth in 2025. Awards per year were flat at 8–10 annually from 2022–2024, then spiked to 375 awards in 2025 and 64 in 2026 year-to-date. This surge reflects the high volume of small-dollar DLA Energy fuel delivery orders, which constitute the bulk of the award count but represent modest individual values. The source shows no recompete cliff signal in the next twenty-four months; only five awards with combined potential value of $435 thousand face completion by mid-2027.

As a subcontractor, Duncan Aviation works under two large defense primes: Northrop Grumman Systems Corporation (multiple 2025 awards for contractor logistics support on special electronic mission aircraft including MC-12, C-12, RC-12, and related platforms) and Sierra Nevada Company (BIG SAFARI temperature control work, September 2025) and Amentum Services (transport aircraft contractor logistics support, August 2025). The sub awards are recent and modest in volume (18 total, 1% of the portfolio).

Service Contract Inventory data shows Duncan Aviation has minimal SCI-reportable prime activity. The SCI dataset records zero invoiced revenue as a prime contractor in FY2022 and no prime service contracts above the $150,000 threshold in the coverage window. SCI does report Duncan Aviation as a named subcontractor on two records in FY2024, reflecting 6.7 FTEs, indicating the company performs labor-hour work under larger primes but does not report significant standalone service-contract revenue to the federal government at the SCI reporting threshold. This aligns with the award evidence: Duncan Aviation operates primarily as a fuel supplier (goods-based, excluded from SCI) and as a sub-performer on larger contractors' logistics and maintenance vehicles.

Duncan Aviation competes across full-and-open federal procurements with no small business set-asides across its recent footprint, positioning itself as a commercial vendor competing on price and capability in the aviation fuel and specialized repair space. The company's federal strategy centers on its DLA Energy fuel IDC—a long-term, high-volume vehicle that generates recurring task-order revenue—supplemented by selective repair work for Air Force and Navy customers and subcontract logistics support for Northrop Grumman and related primes on military special mission aircraft. The combined obligated dollars ($215.3 million across the portfolio) exceed combined potential value by 246%, signaling that many small fuel delivery orders have been completed and paid in full while potential values remain on the books.
