NOC 9521 – Aircraft assemblers and aircraft assembly inspectors



Aircraft assemblers assemble, fit and install prefabricated parts to manufacture fixed wing or rotary wing aircraft or aircraft subassemblies. Aircraft assembly inspectors inspect aircraft assemblies for adherence to engineering specifications. They are employed by aircraft and aircraft subassembly manufacturers.

Aircraft assemblers and assembly inspectors may progress to supervisory positions with experience.

Main Duties

Aircraft assemblers perform some or all of the following duties:

  • Read and interpret aircraft assembly diagrams
  • Assemble and fit pre-fabricated parts to form subassemblies, working at benches or directly on an aircraft structure
  • Assemble, fit and install pre-fabricated parts and subassemblies such as aircraft skins, flight controls, rigging, hydraulics and other mechanical systems.

Aircraft assembly inspectors perform some or all of the following duties:

  • Inspect aircraft assemblies, using measuring and testing equipment, for adherence to engineering specifications
  • Inspect assemblies for alignment, symmetry, dimensions, fit and quality of workmanship
  • Complete detailed inspection documentation.

Employment Requirements

  • Completion of secondary school is required.
  • Completion of a college or other program in aviation or aeronautical technology, with emphasis in aircraft manufacturing, may be required.
  • Aircraft assemblers receive several months of on-the-job and classroom training.
  • Aircraft assembly inspectors require experience as an aircraft assembler.
