AAR Allen Services, Inc.

AAR Allen Services, Inc., a subsidiary of AAR Supply Chain, Inc., provides maintenance, repair, and overhaul services for military aircraft components — primarily helicopter and fighter-jet parts and assemblies — as a prime contractor competing in full and open procurements without set-aside designation. Based in Mineola, New York, the company operates primarily through single-award indefinite delivery contracts with the Army and Air Force, delivering specialized component restoration for platforms including the CH-47F Chinook, UH-60 Black Hawk, F-16, and related engine systems.

The vendor's customer concentration is heavily skewed toward Army Aviation programs. The Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command anchors 104 awards valued at $399.7 million combined potential value — 52% of the contractor's total portfolio and 63% coverage across the top five customers. The Department of Homeland Security US Coast Guard places 58 awards worth $89 million, and the Department of the Air Force, across multiple logistics complexes, accounts for 119 combined awards in the visible footprint. By potential value, Army programs represent 72% of the total $771.6 million across all awards. Award activity has run consistently at 18–20 per year over the past five years, with only two awards in 2026 to date, reflecting the snapshot timing in May 2026.

AAR Allen Services holds a substantial indefinite delivery infrastructure underpinning its business. Nine single-award IDCs with the Army Aviation and Missile Command and Air Force Materiel Command carry combined ceiling values exceeding $220 million and span five-year performance periods ending between 2027 and 2030. The largest vehicle is a $113.1 million UH-60 Black Hawk power-unit and gas-turbine maintenance IDC (ultimate completion November 2028) with three active delivery orders totaling $9.9 million; a $33.3 million CH-47 servo-cylinder overhaul IDC (August 2028) anchors much of the Army Chinook workload; a $25.1 million CH-47 cylinder-assembly IDC was awarded in September 2025 with a five-year ceiling; and smaller dedicated vehicles cover F-16 accessory drive gearbox and jet fuel starter repair ($20.7 million ceiling cited in one award summary), CH-47 flutter dampener work, and CH-47 control assembly maintenance. Task-order velocity under these vehicles is high — the Army Aviation and Missile Command contracts alone represent over 100 awards with delivery orders issued continuously through 2026. Delivery orders are firm fixed price with no set-aside category.

Representative work demonstrates the vendor's component-level repair specialization: a $2.3 million delivery order (May 2024) for UH-60 power-unit and gas-turbine maintenance and overhaul with ultimate completion December 2025; a $3.6 million delivery order (September 2024) for the same scope; a $3.9 million delivery order (May 2024) for UH-60 work extending to December 2025; a $25.1 million five-year CH-47 cylinder-assembly IDC awarded September 2025 with an initial delivery order of $941,238 for CH-47F Block II cylinder overhaul (October 2026 completion); a $2.5 million Air Force delivery order (July 2025) for F-16 auxiliary drive gearbox and jet fuel starter repair at the Ogden Air Logistics Complex; a $1.8 million delivery order (August 2024) for F-16 component repair; and a $2.6 million definitive contract (July 2023) for UH-60M Black Hawk power-unit and gas-turbine overhaul. The vendor also performs specialized work for allied countries through foreign military sales — a $2.6 million August 2024 definitive contract for F-16 accessory drive gearbox test, teardown, and evaluation for Greece, and a $1.1 million definitive contract (July 2025) for auxiliary drive gearbox repairs for Greece.

The company sustains a modest subcontract footprint concentrated in Boeing's CH-47F and F-16 programs and in S&K Logistics Services LLC's foreign military sales support. Sub awards from February 2025 reflect congressional-mandate advanced procurement for CH-47F aerospace support under Boeing primes, and an Egypt foreign military sales servo-cylinder repair sub to S&K Logistics (awarded September 2025). A Lockheed Martin sub from February 2025 covers Taiwan F-16 retrofit program power-unit work. The subcontract position represents only 3% of award count (16 of 535 awards), with the remaining 97% prime.

Performance is consolidated at Garden City, New York; a single May 2022 delivery order specifies Tucson, Arizona, and one Naval Supply Systems Command award cites Smithtown, New York. The vendor's NAICS profile aligns with its work: Other Aircraft Parts and Auxiliary Equipment Manufacturing (218 awards) and Aircraft Engine and Engine Parts Manufacturing (160 awards) dominate, reflecting component-level repair rather than systems integration. Primary PSC codes are Maint/Repair/Rebuild of Aircraft Components (98 awards) and Gas Turbines and Jet Engines (63 awards). Recompete exposure in the next twenty-four months is light — three awards with $4.3 million combined potential value reach ultimate completion by October 2028.
