Avionic Instruments LLC

Avionic Instruments LLC, doing business as Avionics Instruments Inc., manufactures and repairs high-reliability power conversion equipment—inverters, frequency converters, and transformer rectifiers—for military and defense aircraft platforms, operating as a prime contractor on full-and-open federal procurements without set-asides. The company is a subsidiary of TransDigm Group Incorporated, headquartered in Avenel, New Jersey, and competes in NAICS codes covering aircraft parts manufacturing and electrical equipment component manufacturing, with a primary product code alignment to converters and aircraft electrical accessories.

Avionic Instruments' customer concentration is heavily Navy-led. The Naval Supply Systems Command dominates the vendor's award footprint, accounting for 160 prime awards worth $62.9 million in combined potential value—about 52 percent of the total $121.4 million portfolio. The Department of Homeland Security US Coast Guard ranks second with 82 awards valued at $6.7 million, anchored by two single-award indefinite delivery contracts for HC-144 and HC-27J inverter repair services (ceilings of $1.27 million through May 2025 and $2.4 million through May 2028). The Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command places 25 awards worth $14.6 million. Across the top five customers (61 percent of awards), the Navy represents just over half the customer-facing revenue; the remaining concentration spans Coast Guard, Army aviation, and Defense Logistics Agency (both Land and Maritime and Aviation divisions).

Avionic Instruments operates as a prime on full-and-open defense procurements—90 percent of its recent awards are prime contracts, with no reliance on set-asides. Representative prime work includes a $3.45 million March 2025 definitive contract with Naval Supply Systems Command for aircraft inverter design and production; a $4.46 million May 2024 definitive contract for aircraft inverter manufacture; a $1.796 million March 2026 definitive contract for aircraft inverter supply; and a $2.4 million May 2025 Coast Guard indefinite delivery contract for inverter repair supporting HC-144 and HC-27J fleet sustainment. The vendor also holds multiple delivery orders under GSA Federal Supply Schedule GS07F5339A (19 task orders) and several Defense Logistics Agency IDIQs, including a $1.4 million vehicle (SPM4A612D0069 with 16 task orders) and a $578 thousand vehicle (70Z03822DL0000006 with 14 task orders).

The subcontractor footprint is substantial and strategically aligned. Avionic Instruments supplies inverters, frequency converters, and related electrical components to major defense primes including The Boeing Company (CH-47F aircraft systems, P-8A long lead materials, presidential aircraft recapitalization), Lockheed Martin (C-130J aircraft, CV-22 converters, light unit dimmers), Bell Textron (light dimmer and inverter work for AH-1Z helicopters and Nigerian FMS), Sikorsky Aircraft (Combat Rescue Helicopter parts and service), and Sierra Nevada Company (airborne mission networking kits and frequency converters). The vendor also supplies Northrop Grumman, L3Harris, and AAR Government Services on aircraft maintenance and payload integration work. This sub footprint demonstrates deep integration into platform sustainment and production supply chains, particularly for rotorcraft and fixed-wing aviation.

Activity has grown consistently. Awards per year rose from 23 in 2022 to 46 in 2024, with 41 awards in 2025. Seventeen awards (combined potential value $8 million) face ultimate completion within the next twenty-four months, representing modest recompete exposure relative to the overall portfolio scale. The vendor's NAICS concentration—130 awards in Other Aircraft Parts and Auxiliary Equipment Manufacturing, 90 in Miscellaneous Electrical Equipment Manufacturing, and 75 in Air Transportation Support—reflects a specialized electrical-component footprint anchored to military aviation platforms rather than broader defense manufacturing.
