What the government is buying
DLA Aviation at Philadelphia is soliciting bids for a spindle assembly, RU (SPRPA127QRA18). This is a sole-item procurement for an aircraft-related mechanical component. DLA Aviation is the primary procurement organization for the Department of Defense's aviation spare parts and supplies. The agency buys parts to support military aircraft readiness and maintenance operations across the armed services.
Spindle assemblies in aviation contexts typically function as rotating mechanical components within landing gear systems, brake mechanisms, or other aircraft subsystems. The "RU" designation in the title likely indicates a specific model, specification, or unit type within the military supply system. See the solicitation for complete technical specifications, drawings, and performance requirements.

Who can bid
This is a full and open competition with no set-aside program, meaning any qualified business—regardless of size or socioeconomic status—may submit a bid. Under NAICS 333998 (All Other Miscellaneous General Purpose Machinery Manufacturing), the Small Business Administration's size standard is typically 1,000 employees. Businesses should verify their size status in SAM.gov before bidding.
To compete, your firm must:
- Register and maintain active status at SAM.gov
- Hold any required manufacturing certifications for aerospace or defense work (such as AS9100 quality management or ISO 9001)
- Be capable of producing to military/technical specifications, which often include MIL-STD or DLA-unique requirements
- Demonstrate past performance delivering similar precision mechanical components, if required
How to put together a competitive bid
Understand the technical requirements. Aircraft spindle assemblies demand tight tolerances, specific metallurgy, and surface treatments. Request the technical data package early through DLA's TDP access procedures if not automatically provided. Review any applicable military specifications (MIL-SPEC) referenced in the solicitation.
Price strategically for spare parts. DLA aviation procurements often compete on total evaluated price, including shipping to designated depot locations. Factor in:
- Raw material costs and lead times for specialty alloys or forgings
- NDT (non-destructive testing) requirements such as magnetic particle or dye-penetrant inspection
- Packaging and preservation per MIL-STD-2073
- First article testing, if required
Highlight manufacturing capabilities. For an open competition against potentially large OEMs, small and mid-size bidders should emphasize:
- Specialized machining capabilities (CNC grinding, hard-turning, thread rolling)
- Existing approvals for similar NSNs or military part families
- Quick-turn production flexibility or lower overhead structure
Prepare your quote format. DLA Aviation typically requires submission through DIBBS (DLA Internet Bid Board System), not directly through SAM.gov. Ensure your DIBBS account is active and linked to your SAM record.
