Air Shunt Instruments, Inc.

Air Shunt Instruments, Inc., doing business as Air Shunt Instruments, is a Chatsworth, California-based small business that supplies aviation components, mechanical assemblies, electrical systems, and specialized avionics repair services to the Department of Defense and related federal agencies as a prime contractor on purchase orders and indefinite delivery contracts, competing exclusively under full-and-open (non-set-aside) procurement with rare exceptions for Total Small Business set-aside awards.

Air Shunt Instruments operates as a for-profit Subchapter S corporation with no SBA 8(a), HUBZone, SDVOSB, or minority-owned designations in the source material. The vendor has maintained federal contractor registration since October 2001 and brings over two decades of experience supplying specialized aviation hardware to defense logistics organizations. Its primary business spans aircraft components manufacturing and repair services across electrical assemblies, fluid systems, mechanical parts, and avionics maintenance.

The customer footprint concentrates heavily on Defense Logistics Agency divisions. The top five customers account for 92 percent of recent award count: Defense Logistics Agency Aviation (934 awards, $5.2 million combined potential value), Defense Logistics Agency Land and Maritime (715 awards, $3.3 million), Department of Homeland Security US Coast Guard (113 awards, $398 thousand), Department of the Air Force Materiel Command Air Force Sustainment Center (64 awards, $728 thousand), and Naval Supply Systems Command (35 awards, $802 thousand). The two rankings track closely — DLA Aviation and Land and Maritime divisions dominate both volume and dollars — reflecting the vendor's role as a steady-state supplier of discrete components across defense logistics.

Air Shunt Instruments sits on five named indefinite delivery contracts. The active parent vehicles include IDC DTCG3800DH00013 (36 task orders, $7 thousand combined potential value), IDC DTCG3801DH00005 (30 task orders, $12 thousand), IDC FA811709D0006 (16 task orders, $40 thousand), IDC FA811721D0021 (9 task orders, $16 thousand), and IDC DTCG3801D202032 (12 task orders). The Air Force Sustainment Center contract FA811709D0006, valued at $66.5 thousand through March 2031, authorizes autopilot controller repair services for military aircraft including T-38 trainer aircraft and represents the vendor's most significant specialized repair capability.

Recent award activity has grown year over year — 90 awards in 2022, 115 in 2023, 191 in 2024, and 228 in 2025 — with 62 awards recorded through April 2026. The vendor holds 2,047 total awards spanning from June 1998 to April 10, 2026, with combined potential value of $11.4 million and combined obligated dollars of $13.7 million. Five awards totaling $105 thousand in combined potential value reach ultimate completion within the next twenty-four months and face recompete. Air Shunt Instruments operates as a 100 percent prime contractor footprint (2,047 prime awards, zero sub-awards), with no named subcontractor relationships in the source.

Capability concentration reflects Defense Logistics Agency component sourcing patterns: top NAICS codes are Other Aircraft Parts and Auxiliary Equipment Manufacturing (417 awards), Other Electronic Component Manufacturing (124 awards), Search, Detection, Navigation, Guidance, Aeronautical and Nautical System and Instrument Manufacturing (118 awards), Aircraft Engine and Engine Parts Manufacturing (101 awards), and Other Measuring and Controlling Device Manufacturing (91 awards). Top PSC categories include Switches (107 awards), Airframe Structural Components (94 awards), Miscellaneous Aircraft Accessories and Components (81 awards), Hose, Pipe, Tube, Lubrication and Railing Fittings (76 awards), and Maintenance/Repair/Rebuild of Equipment Aircraft Components and Accessories (68 awards).
