Aerospace Inspection Burden at 35% as9100 documentation review allowance: a worked example
What does the result look like when as9100 documentation review allowance reaches 35%? The full calculation is worked below with real intermediate numbers. a quality engineer needs to estimate inspection labor for precision machined aerospace components or flight assemblies
The inputs for this scenario
- Inspection characteristics to verify: 320 characteristics (unchanged)
- Inspection verification pace: 4.8 characteristics/min (unchanged)
- AS9100 documentation review allowance: 35 % (raised for this scenario; the documented default is 30)
Working through the calculation
- Applying the documented formula (Base measurement time = inspection characteristics รท inspection verification pace) to the inputs above produces each figure below.
- At this operating point the engine returns 90 inspection hr for total aerospace inspection burden, the number this scenario is built around.
- At this operating point the engine returns 66.67 inspection hr for base measurement time.
- At this operating point the engine returns 35 % for documentation and setup allowance.
- At this operating point the engine returns 4.8 characteristics/min for inspection verification pace.
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 3.85% above the baseline at 90 inspection hr.
- A figure at this level is achievable when as9100 documentation review allowance is genuinely sustained, not just peaked for a shift. It assumes a steady average pace across all characteristics; in reality GD&T callouts, true-position checks, and CMM program runs vary widely, so use weighted paces for mixed-difficulty parts.
