Turbine Controls, LLC

Turbine Controls, LLC, a Connecticut-based FAA-approved repair station, manufactures and overhauls aircraft engine components—primarily bearing air seals, turbine exhaust cases, and associated propulsion system parts—for the Department of the Air Force as a prime contractor competing under full-and-open (non-set-aside) procurement, with one Total Small Business set-aside IDV among its active vehicle portfolio. Turbine Controls is a subsidiary of VSE Aviation, Inc., which in turn is a subsidiary of VSE Corporation, a publicly traded engineering and technical services firm headquartered in Alexandria, Virginia.

Turbine Controls operates exclusively as a prime contractor with no subcontract footprint; all 374 recent awards in the source are prime delivery orders or IDVs. The vendor's work centers on aircraft engine component repair, overhaul, and remanufacturing—specifically bearing air seal maintenance for F-100, F100-PW-220, and F100-PW-220E engines, and remanufacturing of TF33 turbine exhaust cases. Representative work includes a $48,000 Total Small Business delivery order from the Air Force Sustainment Center for F-100 #3 bearing air seal overhaul (January 2026, ultimate completion January 2027), a $148,200 firm-fixed-price delivery order for TF33 turbine exhaust case remanufacturing (November 2025, completion December 2026), and a $145,200 delivery order for the same TF33 work (September 2024, completion November 2025). All recent awards are firm fixed-price delivery orders or single-award IDVs with no set-aside designation except the $514,760 Total Small Business IDV for F-100 #3 bearing air seal overhaul running through January 2027.

Customer concentration is extreme and monolithic: the Department of the Air Force accounts for 141 of 374 awards (38%), and when narrowed to the Air Force Sustainment Center and broader Air Force Materiel Command, the focus sharpens further. The Air Force Sustainment Center issued 111 awards totaling $16.3 million in combined potential value; the broader Materiel Command portfolio spans 73 awards with $21.1 million combined potential value. The Army's Aviation and Missile Life Cycle Management Command represents the only material secondary customer, with 8 awards and $8.9 million combined potential value. This customer concentration reflects Turbine Controls' specialization in a narrow, mission-critical product line for a single service branch.

Turbine Controls maintains four active IDVs with the Air Force Sustainment Center collectively valued at approximately $3.8 million. The largest vehicles are Indefinite Delivery Contract FA810304D0120 (18 task orders, $10.5 million combined potential value), Indefinite Delivery Contract F3460196D0598 (14 task orders), Indefinite Delivery Contract F3460101D0342 (20 task orders, $1.3 million combined potential value), and Indefinite Delivery Contract FA812110D0030 (13 task orders, $709 thousand combined potential value). The $514,760 Total Small Business IDV for F-100 #3 bearing air seal overhaul remains active through January 2027 and has generated six delivery orders ranging from $18,800 to $85,360 since July 2023. The $706,490 IDV for TF33 turbine exhaust case remanufacturing, awarded March 2022 and extending to March 2027, has sustained recent task order activity with the $148,200 and $145,200 delivery orders cited above.

Activity has contracted sharply in the source window: awards per year declined from 11 in 2023 to 5 in 2024, 1 in 2025, and 1 in 2026 year-to-date. This trajectory reflects either aging of the award cohort in the source or a genuine pullback in task order issuance. Recompete exposure in the next twenty-four months is minimal at $620 thousand across 11 awards, though the two largest active IDVs (FA810304D0120 and F3460196D0598) approaching their ultimate completion dates represent material renewal risk. The vendor's category concentration—140 of 374 awards (37%) in Aircraft Engine and Engine Parts Manufacturing NAICS, and 81 awards in Maintenance/Repair/Rebuild of Engines, Turbines, and Components PSC—underscores deep specialization in a single, Air Force-centric mission set with limited geographic or customer diversification.
