AS9100 Audit Load at 32% corrective-action follow-up allowance: a worked example

Suppose corrective-action follow-up allowance falls to 32%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate AS9100 audit preparation and response hours from audit evidence items, review pace, and corrective-action allowance.

The inputs for this scenario

  • AS9100 evidence items: 180 records (held at the documented default)
  • Audit evidence review pace: 2.5 records/min (held at the documented default)
  • Corrective-action follow-up allowance: 32 % (the input this scenario stresses; the baseline uses 45)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base audit evidence review time = AS9100 evidence items รท review pace.
  • Total AS9100 audit load works out to 95.04 audit hr at these inputs, and this is the headline figure for the scenario.
  • Base audit evidence review time works out to 72 audit hr at these inputs.
  • Corrective-action follow-up allowance works out to 32 % at these inputs.
  • Audit evidence review pace works out to 2.5 records/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where corrective-action follow-up allowance sits at 45% and the headline result is 104 audit hr, this scenario comes in 8.97% below the baseline at 95.04 audit hr.
  • It turns a count of evidence records and a review pace into base review hours, then adds a percentage allowance for corrective-action follow-up. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total AS9100 audit load: 95.04 audit hr (headline result)
