Mason Electric CO.

Mason Electric CO., operating as Mason Controls through its Esterline Mason Division and a subsidiary of TransDigm Group Incorporated, manufactures switches, transducers, grip assemblies, and related electronic and mechanical components for military aircraft systems as a prime contractor to the Defense Logistics Agency and Department of Defense, competing in full-and-open procurements without set-aside designations.

Mason Electric is a for-profit manufacturer based in Sylmar, California, classified under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC 5930 (Switches). The company operates as a child entity within the Esterline Technologies Corporation corporate structure and competes predominantly in full-and-open federal procurements—across the approximately 3,600 awards in the source data, none carried set-aside designations. The vendor holds a position within the TransDigm Group defense industrial portfolio, positioning it as a specialized supplier of human-machine interface and flight control solutions for military aviation platforms.

Mason Electric's capability portfolio centers on specialized electronic and mechanical components for military aircraft. Recent representative work includes a $977,536 purchase order from DLA Aviation for grip assembly components (awarded February 2026), a $365,050 purchase order from DLA Aviation for motional transducers (awarded September 2025), and a $2.3 million indefinite delivery contract from DLA Land and Maritime for toggle switch assemblies running through January 2031. The company supplies push switches, toggle switches, rotary switches, slide switches, guard switches, trigger switches, helical compression and torsion springs, transducers, housings, covers, plates, connectors, control wheels, control assemblies, and electrical leads to military logistics and operations across the Air Force, Navy, and Army.

Customer concentration is dominated by Defense Logistics Agency divisions. The top five customers account for 77% of awards by count, led by DLA Land and Maritime (1,335 awards, $34.2 million combined potential value) and DLA Aviation (911 awards, $59.6 million combined potential value). The ranking by potential value surfaces DLA Aviation as the leading dollar customer ($59.6 million), followed by DLA Land and Maritime ($34.2 million), with Army Materiel Command Aviation and Missile Life Cycle Management Command, Air Force Materiel Command, and Air Force Aeronautical Systems Center rounding out the top tier. The concentration reflects Mason Electric's role as a critical sole-source or sole-approved supplier for specialized components across DLA's aviation and land platforms.

Mason Electric holds three named indefinite delivery contracts: a $2.3 million single-award IDC from DLA Land and Maritime for toggle switch assemblies (awarded January 2026, runs through January 2031), a $750,000 single-award IDC from DLA Aviation for grip assemblies for UH-60 helicopter platforms (awarded July 2025, runs through July 2028), and a $350,000 single-award IDC from DLA Land and Maritime for connector receptacles (awarded March 2026, runs through March 2027). Beyond these named vehicles, Mason Electric places task orders across NAVAIR Strategic Sourcing for CMMARS and multiple other DLA indefinite delivery contracts spanning electrical components, switch assemblies, and specialized aircraft parts.

Activity has remained relatively steady across the past five years, averaging approximately 215 awards annually (2022–2026, with 39 partial-year awards in 2026). Sixty-two awards with ultimate completion dates in the next twenty-four months carry combined potential value of $21.5 million, representing moderate recompete exposure for the vendor and potential opportunity for competitors pursuing DLA supply chain positions.

In its subcontractor capacity, Mason Electric delivers rotary switches, grip assemblies, potentiometers, trigger switches, transducers, and related components to The Boeing Company on multiple Electra/Hydra/Mechanical (EHM) platforms and programs; to Vertex Aerospace on T-45 aircraft maintenance and sustainment task orders; to Lockheed Martin on integrated logistics support and aircraft parts work; to Raytheon on CIWS production; to Bell Textron on performance-based logistics potentiometer services; to BAE Systems Land & Armaments on AMPV material support; and to CAE USA on KC-135 training system components. The subcontract footprint reflects Mason Electric's position as a specialized supplier within broader prime-led defense programs across multiple military platforms and service branches.

Mason Electric's award portfolio is heavily concentrated in switches and miscellaneous aircraft accessories. The top NAICS categories across all awards are Other Aircraft Parts and Auxiliary Equipment Manufacturing (904 awards), All Other Miscellaneous Manufacturing (481 awards), and Other Electronic Component Manufacturing (460 awards). The top PSC categories are Switches (1,661 awards), Miscellaneous Aircraft Accessories and Components (754 awards), and Combination and Miscellaneous Instruments (210 awards). This concentration reflects the company's specialization in electronic switching and control components for military aviation platforms rather than broader industrial manufacturing.
