S & L Aerospace Metals LLC

S & L Aerospace Metals LLC, a minority-owned, Asian-Pacific American-owned small disadvantaged business based in Flushing, New York, manufactures precision-engineered aircraft components and hydraulic systems for military aviation platforms as a prime contractor (92% of recent awards) and as a subcontractor to major aerospace primes. The company is a for-profit limited liability corporation structured as a self-certified small disadvantaged business, competing predominantly under total small business set-asides on direct agency purchase orders and delivery orders.

S & L Aerospace Metals supplies hydraulic systems, landing gear assemblies, helicopter rotor mechanisms, pistons, cylinders, housings, and structural hardware for rotary-wing and fixed-wing military aircraft. Recent representative prime work includes a $3.25 million delivery order from the U.S. Army Aviation and Missile Life Cycle Management Command (awarded May 2023, set-aside for total small business) for cylinder and piston assemblies supporting the UH-60M Black Hawk helicopter program through March 2026; a $258,425 delivery order from the Defense Logistics Agency Aviation (awarded December 2023, total small business set-aside) for housing probes for H-60 Seahawk platforms through April 2026; a $282,485 firm-fixed-price purchase order from the U.S. Coast Guard (awarded September 2026, total small business set-aside) for 35 SAS actuator assemblies for MH-60T helicopters, due February 2027; and a $242,030 delivery order from Department of Defense Aviation (awarded January 2024, total small business set-aside) for housing probes through November 2026. The company also holds two single-award indefinite delivery contracts with DLA Aviation: a $1,999,999.99 IDC (awarded March 2024, no set-aside, through March 2029) for piston assemblies and other critical aviation components, and a $2 million IDC (awarded November 2023, small business set-aside, through November 2028) for housing probes for rotary-wing aircraft, against which three task orders have been issued totaling $578,535 in combined value.

Customer concentration is extreme and centered on Army aviation sustainment. The Army Aviation and Missile Life Cycle Management Command dominates by dollar value at 59% of combined potential value (18 awards, $35.2 million). By volume, the Navy accounts for 123 awards and DLA Aviation carries 118 awards worth $8.7 million combined potential value. The top five funding agencies account for 96% of combined potential value across distinct customer agencies. DLA Aviation and related DLA entities together represent roughly $10.4 million in combined potential value across 221 awards, signaling deep supply-chain integration with defense logistics. The vendor does not hold positions on government-wide vehicles; federal market access is anchored entirely to direct agency relationships and single-award indefinite delivery contracts.

Activity has grown sharply year over year—four awards in 2022 to 34 in 2024—before moderating to 31 in 2025 and three to date in 2026, reflecting the seasonal and project-driven nature of defense aviation sustainment procurement. Eight awards with ultimate completion dates in the next twenty-four months carry combined potential value of $921 thousand, representing modest recompete exposure. In its subcontractor role, S & L Aerospace Metals supplies aircraft parts and specialized components to Sikorsky Aircraft Corporation on CH-53K King Stallion long-lead items, Combat Rescue Helicopter development, and H-53 Phase III programs; to The Boeing Company on F-15EX, F/A-18E, KC-135, and landing gear kits; and to Lockheed Martin Corporation on MH-60R production for foreign military sales. Across 49 recent sub-awards, the company supplies hydraulic assemblies, pistons, cylinders, landing gear components, and structural parts to rotary-wing and fixed-wing platforms. The vendor's federal footprint centers on precision machining and assembly work for UH-60M Black Hawk, H-60 Seahawk, CH-53K, and MH-60 platforms, with both prime and sub revenue flowing from defense aviation sustainment and platform production programs.
