What the government is buying

The Defense Logistics Agency (DLA) Aviation at Philadelphia is soliciting bids for a cylinder assembly item, specifically classified as a "16--CYLINDER ASSEMBLY,O" under federal supply classification code 1660. DLA Aviation is the primary purchasing organization for the Department of Defense's aviation spare parts and related material, supporting military aircraft sustainment worldwide.

Items in FSC 1660 fall within the broader category of aircraft components and accessories. Cylinder assemblies are critical propulsion system components typically associated with internal combustion or turbine engines. DLA Aviation procurements of this nature generally involve manufacturing or supplying parts that must meet strict military specifications and airworthiness standards.

This is a solicitation, meaning DLA is actively seeking priced bids and intends to award a contract based on responses received. No set-aside program applies—see the solicitation for any additional socio-economic provisions or evaluation preferences.

Key facts

Who can bid

This opportunity is open to all responsible sources—there is no small-business set-aside. The NAICS code 336413 classifies this as "Other Aircraft Parts and Auxiliary Equipment Manufacturing." Businesses registered in this NAICS may bid, though SAM.gov registration and active status are required regardless of primary NAICS.

Given DLA Aviation's mission, bidders should expect to demonstrate:

• Quality management systems (typically AS9100 or equivalent aerospace certification)
• Experience with military or FAA-accepted technical data
• Capability to meet first article inspection or test requirements
• Approved CAGE code and valid SAM registration through contract performance period

Small businesses remain eligible to compete even without set-aside; DLA tracks small-business participation metrics and may apply small-business price evaluation adjustments where authorized.

How to put together a competitive bid

Understand the technical requirements. Cylinder assemblies under FSC 1660 likely reference a specific military standard, commercial item description, or engineering drawing. Obtain the complete technical data package referenced in the solicitation. Verify your facility can produce to the exact material, dimensional, and performance specifications—deviations typically require formal approval.

Confirm your supply chain. Specialty alloys, coatings, or machining capabilities may be required. Map your subcontractors and their certifications; DLA may require disclosure and flow-down of quality requirements.

Price strategically. Analyze your true manufacturing cost, including any required testing, packaging (likely MIL-STD-129 compliant), and expected inspection acceptance rates. DLA solicitations are typically lowest-price technically acceptable, meaning meeting all requirements precisely matters more than proposal narrative.

Review DLA's terms. Check for:

• Warranty and traceability requirements
• Republic of origin restrictions (Berry Amendment/domestic sourcing)
• Contract clauses unique to DLA Aviation
• Potential long-term contract or option years structure

Submit through proper channels. Electronic submission via DLA's EBS or SAM.gov as instructed; paper submissions are exceptionally rare.
