3
Aerospace Materials Quality Control

• Quality Control is conducted by a team
• Design engineer
• Materials engineer
• Stress engineer
• Raw materials producer
• Production Planner
• Technician
• Quality Assurance Inspector

4
Aerospace Materials Quality Control Team

• Design engineer- responsible for the general
  design of the aircraft performance, and general
  concept. All of which must be met with available
  materials and manufacturing processes.

5
Aerospace Materials Quality Control Team

• Materials engineer- specifies the materials based
  on properties, cost, size, shape, processing etc.

6
Aerospace Materials Quality Control Team

• Stress engineer- analyzes/refines geometry to
  ensure the material of the components are not
  pushed beyond their properties.

7
Aerospace Materials Quality Control Team

• Raw materials producer- supplies the materials
  for the aircraft, maintains quality control of
  physical properties, identifies material and
  produces certifications to accompany material,
  may package materials to protect from
  environmental damage before use. The materials
  producer may frequently test the material or send
  samples for independent verification.

Aerospace Materials Quality Control Team

• Production Planner-

9
Aerospace Materials Quality Control Team

• Technician- performs the correct processing
  according to standards, verifies certifications
  accompany materials at each step. The technician
  follows procedures and checks off performed steps.
