Certification AI review
AI changed product rule basis review for major change or amended tc on an aging platform
This review supports changed product rule analysis for a major change or amended type certificate on an aging platform. EE maps changed areas, affected areas, prior certification basis, amendment levels, issue papers, special conditions, and supporting rationale. AI assists evidence organization and comparison; certification engineers review every exception. The output is a changed-product basis map with open rationale items and authority-alignment questions.
When this review is needed
- Major change or amended TC on an aging platform is close enough that unsupported claims need to be visible now.
- Several teams have touched the ai changed product rule basis review evidence and the controlled baseline is no longer obvious.
- A supplier, lab, or design group delivered records that must be checked before they are relied on.
- Prior reviews found stale citations, missing dispositions, or configuration drift in the same workstream.
The problem
Changed product rule work is hard because the answer depends on affected areas and amendment levels, not just the part that changed. Old basis data, prior issue papers, and new feature effects can be scattered across decades of records.
What gets reviewed
- Build a revision map for change description, existing certification basis, and affected area map.
- Trace amendment comparison table to the claim, requirement, or finding it supports.
- Review impracticality rationale for stale assumptions and missing dispositions.
- Compare identifiers across change description and prior STC data before the package is released.
- Separate record hygiene issues from gaps that can block ai changed product rule basis review.
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Identify what is missing against the means of compliance.
What gets validated
- Every item in change description resolves to a controlled file, with failures logged when the file or revision is absent.
- Baseline comparison covers existing certification basis, and any mismatch is failed until the owner explains the difference.
- Closure credit from affected area map is accepted only when the cited evidence supports the stated method.
- Reviewer disposition is required for each exception, especially where extraction or screening produced the first flag.
- Change history is checked for copied text that carried an old assumption into the current package.
Evidence normally required
- change description
- existing certification basis
- affected area map
- amendment comparison table
- impracticality rationale
- prior STC data
Common discrepancies
- affected areas missed because cascading effects were never traced.
- impracticality arguments asserted without cost or safety substantiation.
- mismatched bases across sequential STCs on the same airframe.
What is at stake
If the changed and affected areas are mapped poorly, the program can under-scope compliance evidence or invite late authority disagreement. Either path creates rework after the project has already committed to a certification strategy.
How the work runs
Define the change
Identify the product change, affected systems, prior basis, and program decision point.
Map affected areas
Connect changed areas, affected areas, amendment levels, historical records, and issue papers.
Review basis exceptions
Flag unsupported assumptions, missing rationale, and questions needing authority alignment.
Prepare the position map
Deliver the changed-product basis map and closure list for certification leads.
What the buyer receives
- Exception register with owner and blocker status
- Evidence map for ai changed product rule basis review
- Source record request list
- Closure plan by affected milestone
- Reviewer briefing note
Who uses the output
- certification manager assigns closure actions from the discrepancy register.
- STC program manager uses the evidence map in reviewer briefings.
- regulatory affairs lead requests missing source records from the responsible team.
How the work fits into the transaction or program
This belongs before the program locks its amended-basis position or enters authority alignment. It does not decide the changed product rule outcome. It gives certification leads a defensible evidence map for the discussion they still own.
Start with a single asset
Confirm requirements map to substantiating evidence.
Regulatory limits
EE does not issue approvals, make compliance findings, determine airworthiness, or replace the applicant, authorized representatives, or authorities. This ai changed product rule basis review review organizes evidence and records discrepancies so those parties can make their own decisions.
What this review does not cover
- Authority submittal signing
- Compliance findings or approvals
- Replacement of specialist engineering review
- Selection of a software platform or vendor
Specific to this review
- The review distinguishes changed areas from affected areas because they can drive different compliance expectations.
- Prior basis, amendment levels, issue papers, and special conditions are checked together.
- AI helps organize historical records, but engineers decide the basis rationale.
- Authority-alignment questions are preserved instead of softened into internal assumptions.
- The deliverable shows where evidence supports the position and where judgment is still required.

Frequently asked questions
Can AI decide changed product rule applicability?
No. AI can help organize the evidence. The applicant, delegates, and authority retain the decision process.
Why are affected areas so important?
A change can alter compliance expectations beyond the modified part, especially on older certification bases.
