Aerospace Inspection Burden at 22% as9100 documentation review allowance: a worked example

This worked example runs the aerospace inspection burden numbers for a tougher week than the baseline: 22% as9100 documentation review allowance instead of the typical 30%. Estimate inspection hours for aerospace parts from inspection characteristics, inspection pace, and added AS9100 review allowance.

The inputs for this scenario

  • Inspection characteristics to verify: 320 characteristics (held at the documented default)
  • Inspection verification pace: 4.8 characteristics/min (held at the documented default)
  • AS9100 documentation review allowance: 22 % (the input this scenario stresses; the baseline uses 30)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base measurement time = inspection characteristics รท inspection verification pace.
  • Total aerospace inspection burden works out to 81.33 inspection hr at these inputs, and this is the headline figure for the scenario.
  • Base measurement time works out to 66.67 inspection hr at these inputs.
  • Documentation and setup allowance works out to 22 % at these inputs.
  • Inspection verification pace works out to 4.8 characteristics/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where as9100 documentation review allowance sits at 30% and the headline result is 86.67 inspection hr, this scenario comes in 6.15% below the baseline at 81.33 inspection hr.
  • Use it when planning first-article inspection, quoting inspection labor, or sizing the metrology cell for a new aerospace program. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total aerospace inspection burden: 81.33 inspection hr (headline result)
  • Base measurement time: 66.67 inspection hr
  • Documentation and setup allowance: 22 %
  • Inspection verification pace: 4.8 characteristics/min
