Charles R Thurber

Charles R Thurber, doing business as C & M Machining, manufactures precision machined aviation hardware and aerospace components for the Defense Logistics Agency as a prime contractor, operating as a self-certified small disadvantaged business, woman-owned small business, veteran-owned business, and service-disabled veteran-owned business. The vendor is a sole proprietorship based in Thousand Oaks, California, and competes exclusively under small business set-asides, with recent awards spanning Total Small Business and competitive designations.

C & M Machining's federal footprint is entirely DLA-driven and narrowly specialized. The vendor holds a single-award indefinite-delivery contract with DLA Aviation (ceiling $349,999.99, running through February 2031) from which it receives firm fixed-price delivery orders for collars, hinge pin assemblies, mechanical fasteners, and related aircraft maintenance parts coded to specific NSN requirements. Recent delivery orders under this IDC have ranged from $16,100 to $16,800 per order. A February 2026 delivery order for precision machined collar components (NSN 8511932667) valued at $5,625 exemplifies current ordering patterns, with a completion date of February 2027. An earlier November 2024 purchase order from DLA Aviation for collar parts (NSN 1560011572423) carried a value of $57,050 and was associated with the existing indefinite-delivery contract structure.

Customer concentration is severe. DLA Aviation accounts for 120 of 155 total prime awards (77% of the portfolio) and $2.3 million of the $4.2 million combined potential value across all awards. The broader DLA enterprise — including DLA general, DLA Land and Maritime, and DLA Troop Support — adds 18 additional awards but only $777 thousand in additional value. One Department of the Air Force Materiel Command award rounds out the five distinct customer agencies. The vendor competes almost exclusively through small business set-aside delivery orders, with no IDIQs, GWACs, or BPAs in its parent-vehicle portfolio; instead, task orders flow from five DLA indefinite-delivery contracts, with the largest being SPM47504D0419 (11 task orders, $57 thousand combined potential value).

Activity has been episodic. Awards per year averaged five to seven annually from 2021 through 2022, dropped to one award each in 2023 and 2024, and have recently picked up with two awards in early 2026. Only one award ($6 thousand combined potential value) reaches ultimate completion inside the next twenty-four months, indicating limited recompete exposure. The vendor's NAICS profile is dominated by Other Aircraft Parts and Auxiliary Equipment Manufacturing (70 awards) and Small Arms, Ordnance, and Ordnance Accessories Manufacturing (23 awards), with PSC coding concentrated under Airframe Structural Components (102 awards) and Hardware, Weapon System (42 awards). Combined dollars obligated total $1.1 million against $4.2 million potential value, reflecting the firm fixed-price, task-order-by-task-order nature of the work and the time lag between award and invoicing on longer-duration delivery orders.
