Transdigm Inc.

Transdigm Inc. Aero Controlex Group, Inc., doing business as Aerocontrolex, manufactures precision-engineered aerospace and defense components for military rotary-wing and fixed-wing aircraft platforms, delivering 97 percent of its recent awards as a prime contractor to the Department of Defense through the Defense Logistics Agency (DLA). The division is a wholly owned subsidiary of Transdigm Group Incorporated, headquartered in South Euclid, Ohio, and competes under full-and-open procurement with no small-business set-asides, positioning itself as a specialized sole-source supplier of highly engineered aircraft hardware classified primarily under NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing) and PSC 1680 (Helicopter Rotor Blades, Drive Mechanisms and Components).

Aerocontrolex manufactures control assemblies, gearbox assemblies, cable assemblies, fuel metering pumps, valve regulators, clevis rod ends, machine screws, helical retainers, and related mechanical components that support military aircraft maintenance and sustainment across the Department of Defense. Recent representative prime work includes a $973 thousand delivery order from DLA Aviation for cable assemblies (December 2025, awarded without set-aside), a $598 thousand purchase order from DLA Land and Maritime for switch assembly components (January 2026), and a $592 thousand delivery order from DLA Aviation for 32 rotary pumps (June 2025). The division holds five active single-award Indefinite Delivery Contracts with DLA Aviation and DLA Land and Maritime, including a $2.5 million IDC (awarded October 2025, expiring October 2030) for control assembly components for Hercules C-130 aircraft and two IDCs valued at $1.999 million and $750,000 respectively (both expiring 2028–2030) for control assembly units supporting Sikorsky Aircraft platforms.

Customer concentration is acute and defense-focused. DLA Aviation alone represents 316 awards carrying $52.3 million in combined potential value (about 91 percent of all dollars), with DLA Land and Maritime adding 56 awards valued at $2.9 million. The top five funding entities account for 90 percent of award count; DLA Aviation and DLA Land and Maritime together represent approximately 98 percent of combined potential value across the entire portfolio. Aerocontrolex has served 23 distinct federal agencies, but the Army, Navy, and other non-DLA customers contribute negligibly by dollar volume.

Aerocontrolex operates predominantly through DLA IDCs and spot purchase orders against those vehicles. The division's largest parent vehicle is IDC SPE4AX18D9007 (DLA Aviation, non-DLA-specific designation), which carries 55 task orders valued at $4.3 million. Other active vehicles include W56HZV20D0062 (13 task orders) and W56HZV21D0001 (11 task orders), both Army contracts of unspecified dollar scope, plus DLA-specific IDCs SP046003D1447 (8 task orders, $543 thousand) and SPM4A706D3161 (8 task orders, $455 thousand). Work is performed in South Euclid and Cleveland, Ohio.

Award activity accelerated sharply: 2024 saw 41 awards, growing to 81 in 2025, though year-to-date 2026 shows only 18 awards in the source snapshot. Seventeen awards (combined potential value $1.8 million) reach ultimate completion inside the next twenty-four months, creating recompete exposure in late 2026 and 2027. Combined obligated dollars ($75.9 million) exceed combined potential value ($57.5 million) by 32 percent, indicating historical overrun or contract modifications that have pushed cumulative spend beyond original ceilings.

Aerocontrolex subcontracts to major aerospace primes. Named sub-award relationships include General Dynamics Land Systems (M1 Abrams tank production and upgrades, five recent awards as of May 2026), Honeywell International (Tiger and Tiger III control cable assemblies and gearbox accessories for F-15 and foreign military sales, eight awards since April 2024), Vertex Aerospace (aircraft parts and auxiliary equipment manufacturing, two awards December 2024), L3Harris Technologies (nonferrous metal components for Big Safari programs, two awards), and General Electric (PBL service support for aviation engine hardware, one award August 2024). These sub engagements signal deep integration into the broader defense supply chain for advanced rotorcraft and armored vehicle platforms.

The division's award portfolio concentrates in aircraft accessories: Other Aircraft Parts and Auxiliary Equipment Manufacturing (361 awards), Aircraft Engine and Engine Parts Manufacturing (118 awards), and Military Armored Vehicle, Tank, and Tank Component Manufacturing (29 awards). PSC distribution reinforces aircraft focus—Miscellaneous Aircraft Accessories and Components (295 awards), Miscellaneous Engine Accessories for Aircraft (121 awards), and Helicopter Rotor Blades and Drive Mechanisms (84 awards) dominate the mix. Aerocontrolex's specialized role as a sole-source supplier of mission-critical components reflects the technical and quality barriers protecting its position with DLA Aviation, where single-award IDCs and non-competitive delivery orders recur across the portfolio.
