FAQ

What work fits NAICS 336412?
  • Production of turbofan or turboprop engine assemblies and major rotating components with documented manufacturing and acceptance testing.
  • Manufacture of precision engine parts such as turbine disks, compressor blades, shafts, and housings with balancing and heat treatment controls.
  • Supply of serialized replacement parts and serviceable components with full material traceability and part-numbered documentation.
  • Provision of production acceptance testing, run-in cycles, vibration analysis, and qualification test reports for newly manufactured engines or modules.
When is NAICS 336412 a weak fit?
  • Aircraft maintenance, repair, and overhaul (MRO): missing new-production manufacturing controls, qualification of production processes, and original part fabrication responsibilities.
  • Aerospace systems and avionics integration: missing rotating engine component fabrication, production tolerances, and engine acceptance testing.
  • Small auxiliary power units or aftermarket repair shops: missing full engine manufacturing, production transfer, and serial-numbered traceability for main propulsion engines.
What solicitation language points to NAICS 336412?
  • Specification requires production drawings, heat treatment certifications, material lot traceability, and serialized part documentation for delivery.
  • Performance includes dimensional tolerances, dynamic balancing limits, run-in and acceptance testing, and life-limited part records.
  • Labor categories include precision machinist, metallurgist, nondestructive testing technician, and quality assurance engineer with aerospace manufacturing experience.
