FAQ

What work fits NAICS 333618?
  • Fabrication and assembly of accessory engine modules such as starters, gear housings, and accessory drives delivered as separate subassemblies with test reports.
  • Production of turbocharger hardware components and housings requiring balance, pressure testing, and dimensional interchangeability per buyer drawings.
  • Manufacture of auxiliary power unit components and subsystems with documented run-in tests and vibration acceptance records.
  • Supply of engine-mounted pump and blower assemblies produced and tested to specified operational and mounting interface requirements.
When is NAICS 333618 a weak fit?
  • Complete engine manufacturing where the procurement requires full engine build and integration; missing the component-only fabrication and subassembly boundary of this NAICS.
  • Engine repair, overhaul, or field maintenance contracts that focus on remanufacture, inspection, and repair services rather than producing new engine components in a manufacturing environment.
  • Heavy structural casting or non-engine-specific metal fabrications where the product lacks engine-specific balancing, dynamic testing, or functional test requirements present in this NAICS.
What solicitation language points to NAICS 333618?
  • Specifications that require dynamic balancing, run-in testing, or vibration certification for delivered components and subassemblies.
  • Engineering drawings with callouts for bearing fits, interference tolerances, and material heat-treatment specifications tied to interchangeability.
  • Labor categories or evaluation criteria listing machinists, test cell operators, balancing technicians, and metallurgical material verification as required skills.
