The real cost of manual FAI inspection.
First article inspection feels free because no one invoices you for it — it is just the quality engineer doing their job. But manual FAI is one of the most expensive routine activities in a precision shop. Here is a worked rupee breakdown of what it actually costs per report and per year, plus the hidden cost most managers never put a number on.
Where the FAI time actually goes
When people picture inspection cost they imagine measuring. In practice, measuring is the small part. For a machined part with 80 characteristics, the time splits roughly like this in a manual workflow: numbering the drawing by hand, transcribing every nominal and tolerance into the template, formatting the AS9102 or PPAP forms to the customer's layout, and only then recording actual measurements. In my years running plants, the paperwork around the measurement always dwarfed the measurement itself.
That distinction matters, because the paperwork is exactly the part that software removes. You will always have to measure the part. You do not have to hand-number 80 balloons and retype 80 tolerances.
Cost per FAI report
Take a realistic Indian precision shop and a part with 60 to 100 characteristics. A loaded quality-engineer cost of 700 rupees per hour is typical once you include salary, benefits, and overhead.
| Step | Manual time | Cost at 700/hr |
|---|---|---|
| Ballooning the drawing | 1.5 – 2.5 hr | 1,050 – 1,750 |
| Transcribing nominals & tolerances | 1.0 – 1.5 hr | 700 – 1,050 |
| Formatting AS9102 / PPAP forms | 1.0 – 1.5 hr | 700 – 1,050 |
| Recording measurements | 0.5 – 1.0 hr | 350 – 700 |
| Total per report | 4 – 6.5 hr | 2,800 – 4,550 |
So a single FAI report costs roughly 2,800 to 4,550 rupees in direct labour before anything goes wrong. Notice that the first three rows — the pure paperwork — make up the large majority of that number.
Cost per year
Per-report cost hides the scale. Multiply by volume and the picture changes.
| Reports / month | Direct cost / month | Direct cost / year |
|---|---|---|
| 10 | 28,000 – 45,500 | 3.4 – 5.5 lakh |
| 20 | 56,000 – 91,000 | 6.7 – 10.9 lakh |
| 30 | 84,000 – 1,36,500 | 10.1 – 16.4 lakh |
A shop turning out 20 first articles a month is spending on the order of 7 to 11 lakh rupees a year just on FAI labour — and again, most of that is paperwork, not metrology.
The hidden cost: rejected submissions
The table above is only direct labour. The bigger number is rework. Manual transcription introduces errors — a transposed tolerance, a missed characteristic, a wrong datum. When the customer's quality gate catches it, the entire FAIR package bounces.
This is why reducing manual transcription pays twice: you save the hours, and you cut the error rate that triggers the expensive rejections in the first place. If your rejections cluster around missed or mis-typed characteristics, see the PPAP submission checklist for the elements customers reject on most.
How to cut the cost
You cannot cut measuring time much — the part still has to be measured. You can nearly eliminate the paperwork three ways:
- Auto-balloon the drawing. Instead of hand-numbering, let software read the PDF and number every dimension, tolerance and GD&T frame. CadNexa's auto-ballooning tool uses Smart Detect and Box+Balloon OCR to pull the nominal, tolerance and characteristic type straight off the drawing.
- Auto-populate the forms. Once balloons carry the data, the AS9102 or PPAP form fills itself; the engineer only enters actual measured values.
- Standardise the template. Reusing a fixed inspection template removes the formatting hour entirely.
Between them these steps typically take a five-hour report under an hour. On 20 reports a month, that is the difference between roughly 8 lakh a year and under 2 lakh — before you even count the avoided rejections.
Common costing mistakes
- Counting only measurement time. The paperwork is 70 to 80 percent of the effort; leaving it out understates the cost badly.
- Using bare salary, not loaded cost. Benefits and overhead roughly double the true hourly rate.
- Ignoring rejection rework. The rework and shipment delay from bounced submissions is usually the single largest line item.
- Treating FAI as fixed. It is one of the most automatable tasks in the plant; assuming it cannot change is the most expensive assumption of all.
