Hartwell Corporation

Hartwell Corporation, a subsidiary of TransDigm Group Incorporated, manufactures aircraft latches, latching systems, and related hardware for military and commercial aviation as a large business prime contractor (99% of recent awards) competing in full-and-open federal procurements with no set-aside designation. The Placentia, California-based company operates under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC Airframe Structural Components, drawing on more than four decades of Defense Logistics Agency relationships.

Hartwell's customer concentration is heavily weighted to DLA's hardware and aviation logistics operations. The top five customer offices account for 90% of awards by count, led by DLA Troop Support Hardware (1,957 awards, $39.6 million combined potential value) and DLA Aviation (1,656 awards, $58.9 million combined potential value), followed by DLA Troop Support Construction and Equipment, DLA Land and Maritime, and DLA corporate. By dollar value, DLA Aviation leads the ranking at $58.9 million despite lower award count, signaling higher unit values for aircraft-specific assemblies versus commodity hardware. Hartwell's narrow customer base—25 agencies—is effectively DLA-dominated, with Defense Logistics Agency components accounting for roughly 81% of all potential value.

Hartwell's vehicle position is anchored to DLA indefinite delivery contracts. Five parent IDCs account for the bulk of task-order volume: Indefinite Delivery Contract SPE5EN18D0003 (642 task orders, $6.1 million combined potential value), SPE5EN15D0013 (441 task orders, $5.9 million), SPM5L507D0267 (277 task orders, $6.8 million), SPM5L510D0075 (127 task orders), and SPM5L511D0003 (92 task orders). Recent awards show six single-award IDCs held by Hartwell: a $900,000 DLA Aviation contract for latch assemblies (November 2025–November 2028), a $350,000 DLA Land and Maritime contract for flush catches (effective December 2025–December 2026), a $350,000 DLA Land and Maritime mortise latch contract (January 2026–January 2027), a $350,000 DLA Land and Maritime friction catch contract (December 2025–December 2026), and a $250,000 DLA Land and Maritime control lever contract (September 2025–September 2026). All are firm fixed-price vehicles with estimated order frequencies of four to twelve orders annually and guaranteed minimums, enabling rapid procurement of flight-critical components.

Activity has grown over the past five years. Hartwell received 129 awards in 2022, growing to 282 in 2025, then moderating to 39 in the first five months of 2026 (an incomplete year). Combined potential value sits at $184.1 million across all 6,198 awards, with $146.2 million obligated (79% utilization rate). Twenty awards facing completion within the next twenty-four months represent $379 thousand in potential recompete exposure—minimal relative to Hartwell's overall footprint and reflecting the short-cycle, transactional nature of its DLA hardware business.

Hartwell's subcontractor work is minor (1% of awards, 36 sub-awards) but strategically high-impact. Recent prime relationships include Bell Boeing Joint Project Office on V-22 Osprey nacelle improvements (compression latch assembly work, August 2025), Boeing on C-17 Globemaster III sustainment (February 2026) and E-4B fleet sustainment (December 2025), and Boeing on FY24 C-17 virtual fleet material requirements (September 2025). These primes value Hartwell's specialized latch and latching-system expertise for major military rotorcraft and transport aircraft programs.

Category concentration reflects Hartwell's core business: Hardware Manufacturing dominates the NAICS count (3,550 awards), followed by Other Aircraft Parts and Auxiliary Equipment Manufacturing (964 awards). By PSC, Hardware, Commercial ranks first (3,954 awards), with Airframe Structural Components second (933 awards). The vendor's footprint spans latches, hinges, catches, fasteners, and actuators—all flight-critical aircraft maintenance and repair components procured on a just-in-time basis by DLA depots to support military aviation readiness.

Hartwell does not hold seats on government-wide acquisition contracts (GWACs) or federal schedules visible in the source; its business is routed entirely through DLA single-award IDCs. The company competes open-market across all responsible sources, reflecting its large business status and approved-source standing on multiple National Stock Numbers. Obligated dollars (79% of potential value) indicate strong execution and repeat ordering from an established, qualified supplier whose manufacturing and quality certifications meet stringent military aerospace standards.
