What the government is buying

The Department of the Navy, through NAVSUP Weapon Systems Support Philadelphia, is soliciting offers for repair and modification work on aircraft turbine components. This falls under FSC 1660—turbine systems and components used in aviation applications. NAVSUP WSS Philadelphia is the Navy's primary aviation logistics support activity, managing spare parts and maintenance for naval aircraft.

Aircraft turbine repair and modification contracts typically involve depot-level maintenance, overhaul, and engineering changes to gas turbine engines or their subassemblies. Work may include disassembly, inspection, replacement of worn or time-limited parts, reassembly, testing, and certification to return components to serviceable condition. The specific scope of turbine models, repair lines, and technical requirements for this solicitation—see the solicitation.

Key facts

Who can bid

This is an unrestricted solicitation with no small business set-aside. All responsible offerors—large and small businesses alike—may submit proposals. However, small businesses should note that NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) carries a size standard of 1,250 employees. Companies at or below this threshold qualify as small for this procurement if they meet SBA affiliation rules.

Bidders must demonstrate capability in aircraft turbine repair, typically evidenced by:

• FAA Repair Station certification (DCMA- or military-approved capabilities preferred)
• Experience with military technical data, including Military Standard (MIL-STD) specifications
• Quality systems meeting ISO 9001 or AS9100 standards, plus NADCAP accreditation for special processes
• Security clearance facilities if classified data is involved—see the solicitation

How to put together a competitive bid

For turbine repair work, the Navy evaluates proposals on technical merit, past performance, and price. Specific strategies:

Technical proposal: Detail your repair process flow, throughput capacity, and turnaround times. NAVSUP WSS prioritizes responsiveness to fleet readiness needs. Include your engineering change proposal capability, non-destructive testing equipment, and thermal spray or plasma coating facilities if applicable.

Past performance: Cite directly relevant contracts—same engine families (F404, F414, T700, or other naval turboshaft/turbofan models). Navy evaluators weight military aviation depot experience heavily.

Cost/price: Develop should-cost estimates for each repair line or work unit code. Understand whether this is a fixed-price per-item contract, indefinite-delivery/indefinite-quantity, or requirements-type vehicle—see the solicitation. Material costs for turbine blades, vanes, and seals fluctuate; address escalation and long-lead items.

Small business positioning: Without a set-aside, emphasize competitive niche—specialized processes, faster turnaround, or sole-source technical capabilities that large OEMs cannot match.
