Arista Aviation Services, Llc.

Arista Aviation Services, LLC, operating as United Aero Group, is a for-profit limited liability company based in Enterprise, Alabama, that delivers depot-level maintenance, programmed maintenance, component overhaul, and repair services for rotary-wing military and government helicopters as a prime contractor (100% of recent awards). The vendor competes predominantly in the open market without set-aside restrictions, though recent IDC vehicles carry Total Small Business set-aside designations at award.

Arista's customer base concentrates sharply with the Department of State's Bureau of International Narcotics Law Enforcement, which accounts for 41 awards and $350.1 million in combined potential value — 56% of the vendor's portfolio. The Air Force's Warner Robins Air Logistics Complex, Air Force Sustainment Center, and Air Force Life Cycle Management Center at Robins AFB together account for $223.8 million across 36 awards. Defense Contract Management Agency rounds out the top five with 5 awards and $46.8 million. Top-customer rankings align closely by volume and dollars, reflecting sustained, high-value work across military helicopter platforms rather than many small orders. The vendor holds three major IDCs: a $172.9 million Total Small Business single-award IDC with Warner Robins Air Logistics Complex through December 2032 for depot-level maintenance of 28 TH-1H training helicopters; a $100 million Total Small Business IDC with the Bureau of International Narcotics Law Enforcement through February 2027 for UH-1 programmed depot maintenance and H-60 repairs supporting Peru, Iraq, Uruguay, and Panama counter-narcotics operations; and a $40 million Total Small Business IDC with the Bureau of International Narcotics Law Enforcement through November 2029 for T700 and PT6 turbine engine purchase, overhaul, and repair. Task orders flow regularly from these vehicles: 28 delivery orders under the Warner Robins IDC totaling $85.6 million combined potential value, 17 delivery orders under Air Force IDC FA855219D0002 totaling $34.3 million, and nine delivery orders under the State Department's $100 million IDC totaling approximately $12.8 million as of November 2024.

Representative capability work includes a $2.59 million Total Small Business delivery order awarded March 26, 2026, for TH-1H Huey II depot maintenance with the Air Force; a $1.99 million delivery order for refurbishment and return to service of eight UH-1H aircraft (tail numbers 67-17339, 67-17669, 71-20305, 73-21744, 73-21791, 73-21859, 74-22299, 74-22336) under Bureau of International Narcotics Law Enforcement; a $6.74 million delivery order for UH-1 programmed depot maintenance and H-60 repairs supporting Peru; and recurring delivery orders for UH-1N transmission assembly overhaul, dynamic component repair, and T700-series engine evaluation and repair, many in the $0.3 million to $1.1 million range. Work is performed exclusively at Arista's Enterprise, Alabama facility.

Activity shows relative flatness over the past five years — 14 awards in 2022, declining to 5 in 2025, with only 1 award in the first quarter of 2026. However, the underlying dollar picture masks this trajectory: the recent $172.9 million Warner Robins IDC award (December 2024) and the $40 million State Department IDC recompete (November 2024) anchor the vendor's long-term pipeline through 2032 and 2029 respectively. The recompete cliff presents minimal near-term pressure: only 2 awards with ultimate completion inside the next twenty-four months carry combined potential value of $4.8 million. Arista holds no subcontract footprint in the source data; the vendor operates as a pure prime across all 85 awards.

Arista Aviation Services, LLC is a subsidiary of OAS Aircraft Support, LLC, a partnership or limited liability partnership entity. Arista's award portfolio concentrates on PSC codes for maintenance, repair, and rebuild of rotary-wing aircraft and components, with leading NAICS category Aircraft Manufacturing (70 awards). The vendor's federal customer set, contract vehicle holdings, and sustained sole-source and competitive access to military aviation sustainment work position it as a specialized, captive provider to defense helicopter fleet sustainment infrastructure rather than a broad-market contractor.
