Applicability assurance
Every directive that applies. And a reason for every one that doesn't.
Aviagent starts from the registration mark. For each aircraft it determines which airworthiness directives apply, which apply only if certain parts are fitted, and why the rest do not. This page sets out what we commit to, and how we check that we keep those commitments.
What you see for each aircraft
Three answers, never a bare number
Covering FAA and EASA directives, including the Transport Canada and ANAC directives EASA has adopted.
Mandatory for this aircraft
Directives that apply to this airframe, its variant and its installed engine, with live status and due dates.
Depends on installed parts
Directives that apply only if a listed part number is fitted. Shown separately, for your engineers to confirm.
With the reason
In your account, each directive left off the list shows why, so an auditor can follow the decision.
Our commitments
What we commit to
- QA-1
Anchored to the type certificate
Every aircraft is linked to its type certificate using the official civil aircraft register before any directive is matched. An aircraft we cannot link is shown as “coverage unknown”, never as a clean result.
- QA-2
No evidence, no removal
A directive leaves an aircraft’s list only when there is positive evidence that it does not apply to that aircraft. When the data is uncertain, the directive stays on the list. Missing a directive is the unsafe direction, so that is the direction we refuse to err in.
- QA-3
One answer, everywhere
A registration should give the same directive list in your account and in our public lookup. Any difference between the two is treated as a defect and fixed at the source.
- QA-4
Never a guess
Where two certificates or two readings conflict, we do not pick one. The aircraft is held for engineering review and shown as such.
- QA-5
AI is labelled
Where AI helps read a directive’s text, the result is marked as AI-assisted and links to the official document. Dates and identifiers always come from the authority’s own record.
How quality is checked
The control cycle behind every change
Applicability changes when authorities publish, when registers change, and when we improve the engine. Every one of those changes goes through the same cycle.
- 1 · Refresh
From the authorities
New and revised directives and register changes are collected from the publishing authorities.
- 2 · Rehearse
Tested before it is live
Every change runs first in a separate environment, never directly on customer data.
- 3 · Measure
Aircraft by aircraft
We compare each aircraft’s list before and after the change and read the directives that moved, in both directions.
- 4 · Gate
Quality gate
A new register goes live only after a sample across many aircraft types passes our checks, including agreement between all views.
- 5 · Cross-check
Against authority data
Results are compared per type with the authorities’ own applicability data wherever it exists.
- 6 · Record
Reversible and documented
Every change is logged, can be reversed, and is recorded in our quality management system. Engineering analyses need two reviewers before release.
Limits we state openly
What Aviagent does not do
- It does not replace your CAMO’s airworthiness judgement. It gives your engineers a complete, explained starting point.
- It does not mark parts-dependent directives as complied. Your engineers confirm what is fitted.
- It does not present partial coverage as complete. Types outside the FAA and EASA certificate base are shown as “coverage unknown”.
