What you will be able to do

  • ✓ Explain what makes a manufacturing process special and how EU Part 21 Subpart G, 14 CFR Part 21 Subpart G and AS9100D require it to be controlled.
  • ✓ Describe aluminium and steel heat treatment, temper designations and furnace pyrometry, and judge a temperature uniformity survey.
  • ✓ Compare anodising, conversion coating, plating and passivation, control a chemical process line, and calculate anodising current and time.
  • ✓ Explain shot peening intensity, saturation and coverage, read an Almen saturation curve, and outline weld and braze control.
  • ✓ Prevent hydrogen embrittlement through bake timing, oven records and lot testing, using the ATSB findings on embrittled R22 clutch nuts.
  • ✓ Use Nadcap accreditation, audits and purchase-order flow-downs to control special processes in the supply chain.
