The cheap audit is the audit
Years of paper task cards and logbooks become RAAS rows — in a scanning project, or card by card as work flows through. This report prices the three ways to know those records' true error rate — trust them, re-check everything, or measure it with a statistical sample. Parameters tagged RAAS would fill themselves from your data — synthetic here; the YOURS ones are yours to set or challenge.
Review queue — what your AME checks
1,219 records
61.0 AME-hours · 3.0% of the pile
What a repeat cycle costs — your team, after handover
$5,962
$149.04 per 1,000 records
Recoverable unbilled work — estimate
~$152,000
vs. the CAD $24,000 one-time fee — about 6.3× on the engagement
Driven by record count and the two unbilled-work assumptions in Filters — the error-rate sliders don't touch it.

1,200–12,000 bad records — unmeasured
You suspect 8% — about 3,200 wrong records. But unmeasured paper runs 3–30% in the trade press, and you don't know which shop you are. Neither does the airline that audits you next year.
$130,000
2,000 AME-hours
Plus the part the invoice never shows: 2,000 hours off aircraft is $240,000 of billable work not done — in a market where the chairs are already empty.
$5,962
true error rate to a ±1.5-pt margin of error
The software reads all 40,000; a licensed AME verifies 1,219. You get a documented error rate, a fix list sorted by record class, and a number you can defend.

What the numbers say
Recomputed live from the parameters on the right
At 40,000 records and a suspected 8% error rate, the AME review queue is 1,219 records — about 61 hours, a week and a half of one person's time, not a season of the whole hangar's. The software reads everything; the licence holder checks the sample; the same sampling math auditors and pollsters use carries the rest. The CAD $24,000 engagement fee is one-time — method, calibration, the first full audit, handover; after that, a repeat cycle costs your own team about $5,962 to run. On the two assumptions above, that's ~$152,000 of recoverable billing against the $24,000 fee — the engagement pays for itself about 6.3× over before you price a single avoided audit finding.
What the auditor sees: a documented error rate with a stated margin of error — the data-integrity evidence TC AC 571-006 asks for before authorizing electronic record-keeping.
