Lbz, L.l.c

Lbz, L.l.c, doing business as Platinum Aerostructures, manufactures precision aerospace structural components—aircraft skin, panels, ribs, stiffeners, trailing edges, and related parts—for military aircraft maintenance and sustainment, operating as a prime contractor almost exclusively to the Defense Logistics Agency Aviation under small business set-asides. The company is an SBA-certified HUBZone firm and self-certified service-disabled veteran-owned small business and small disadvantaged business, headquartered in Nevada, Missouri, where all manufacturing and performance occurs.

Platinum Aerostructures competes predominantly under Total Small Business set-asides and HUBZone designations; the vendor's footprint is almost entirely HUBZone and small disadvantaged business set-aside work. The concrete capability portfolio centers on fabrication and delivery of high-precision aluminum and composite structural aerospace components. Representative prime contract work includes a $1,056,240 definitive contract awarded May 9, 2024, to manufacture and deliver 405 structural panels (NSN 1560-01-642-0824) under a total small business set-aside; a $296,191 delivery order awarded December 12, 2023, for structural aircraft panels under total small business set-aside; a $2.5 million Indefinite Delivery Contract awarded October 14, 2025, for C-135 aircraft skin components (NSN 1560-01-104-7408) under total small business set-aside with a 60-month term; and a $2.0 million Indefinite Delivery Contract awarded May 29, 2024, for C/KC-135 structural panels (NSN 1560-00-427-9206) with an estimated annual requirement of 36 units. The vendor also performs first article testing and qualification work; recent examples include purchase orders for contractor first article test (FAT) valued at $4,633 and $4,311 awarded September 2025.

Customer concentration is extreme and binary: DLA Aviation accounts for 515 of 535 total prime awards (96% by count) and $33.1 million of $39.5 million combined potential value (84% by dollars). The remaining four Air Force and Army Materiel Command agencies collectively represent 20 awards and $6.5 million. The vendor has no subcontracting footprint; all 535 awards are prime contracts.

Platinum Aerostructures holds eight active single-award Indefinite Delivery Contracts with DLA Aviation, all designated Total Small Business set-asides: a $2.5 million IDC for C-135 aircraft skin (awarded October 14, 2025, completion October 13, 2030); a $2.0 million IDC for C/KC-135 structural panels (awarded May 29, 2024, completion May 28, 2029); a $2.0 million IDC for aircraft skin (awarded May 16, 2023, completion May 15, 2028); a $350,000 IDC (awarded January 26, 2026, completion January 22, 2031); a $350,000 IDC (awarded March 16, 2026, completion March 15, 2031); a $250,000 IDC (awarded June 26, 2025, completion June 25, 2030); and a $250,000 IDC (awarded January 9, 2024, completion January 4, 2029). These vehicles support recurring delivery orders for military aircraft structural components and position Platinum Aerostructures as DLA Aviation's primary small business supplier for specialized aerospace parts. The top named parent vehicles by task order volume are Indefinite Delivery Contract SPE4A719D0169 (13 task orders, $726 thousand), contract FA810211D0009 (8 task orders, $2 million), and Indefinite Delivery Contract SPE4A715D5294 (8 task orders).

Activity has grown year over year with notable volatility: 27 awards in 2022, 36 in 2023, 20 in 2024, 42 in 2025, and 13 awards through March 2026. Within the next twenty-four months, 31 awards (combined potential value $405 thousand) reach ultimate completion date, representing modest recompete exposure concentrated in smaller purchase orders and near-term delivery order completions. The source describes Platinum Aerostructures as having served as a subcontractor to Boeing on prior aerospace manufacturing work, validating technical capability to meet stringent government and industry specifications, though no active Boeing or other prime-contractor relationships are documented in the current award dataset.

NAICS and PSC concentration aligns tightly with core business: 520 of 535 awards fall under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing); 532 awards carry PSC code for Airframe Structural Components. The vendor competes exclusively in the small business set-aside landscape; no full-and-open awards or non-set-aside prime contracts appear in recent activity. Platinum Aerostructures' entire federal footprint is a specialized, repeatable supplier relationship with DLA Aviation for small-volume, precision aerospace structural components under total small business and HUBZone set-asides.
