Certification evidence

Issue paper and CRI response evidence evidence review for the agreed certification basis

This review is for OEMs, avionics suppliers, Certification teams responsible for issue paper and CRI response evidence. It is triggered by issue paper or CRI issued on the program. EE checks issue paper or CRI position, its stage or classification, applicant response against each stated concern, plus the governing plan or application, against the agreed certification basis. Discrepancies include missing source records, mismatched configuration, unsupported assumptions, or responses that restate the applicant position without addressing the authority concern. Output includes Issue paper and CRI response evidence exception register, Claim to evidence map, Reviewer question list.

When this review is needed

Submittal planning has reached the issue paper and CRI response evidence evidence package.
A reviewer has questioned one cited claim or missing source record.
A change to configuration, installation, or intended use may affect prior evidence.
The program needs an exception list before formal review.

The problem

The hard part is proving the applicant response to an FAA issue paper or EASA Certification Review Item actually resolve the authority position with new substantiation with records that match the reviewed configuration. A tidy index still fails if responses that restate the applicant position without addressing the authority concern or if the cited record belongs to another baseline.

What gets reviewed

Review issue paper or CRI position against the configuration, installation, or claim under review.
Compare its stage or classification against the configuration, installation, or claim under review.
Trace applicant response against each stated concern against the configuration, installation, or claim under review.
Challenge evidence cited in the response against the configuration, installation, or claim under review.
Reconcile whether it exists in the data package against the configuration, installation, or claim under review.
Confirm closure status tracking across revisions. against the configuration, installation, or claim under review.

What gets validated

Pass check: issue paper or CRI position must match the released configuration and the claimed means of compliance.
Configuration check: its stage or classification must match the released configuration and the claimed means of compliance.
Trace check: applicant response against each stated concern must match the released configuration and the claimed means of compliance.
Rationale check: evidence cited in the response must match the released configuration and the claimed means of compliance.
Closure check: whether it exists in the data package must match the released configuration and the claimed means of compliance.

Evidence normally required

Controlled issue paper or CRI position
Released its stage or classification
Signed applicant response against each stated concern
Current evidence cited in the response
Archived whether it exists in the data package
Supplier closure status tracking across revisions.

Common discrepancies

Gap: responses that restate the applicant position without addressing the authority concern.
Mismatch: evidence cited that was never delivered.
Unsupported claim: stale response drafts circulating after the authority revised its position.

What is at stake

Late discovery can reopen tests, analysis, or plan wording after schedules have already assumed closure. The worst cases involve evidence cited that was never delivered because they need technical support, not cleaner prose.

Move from findings to resolution

Identify the missing data behind the finding.

How the work runs

Frame Issue Paper

Confirm the exact event, affected file set, buyer role, and decision standard before any issue paper or cri position is treated as sufficient.

Trace Response Evidence

Walk the named evidence from index entry to source artifact and mark where the trail supports, conflicts with, or fails to answer the page-specific question.

Sort Agreed Certification

Group exceptions by closure route: document retrieval, data correction, engineering disposition, authority response, or contractual decision.

Package Positions Backed

Deliver the exception list, evidence map, and owner sequence in a form that can move directly into remediation, submittal cleanup, or transaction negotiation.

What the buyer receives

Issue paper and CRI response evidence exception register
Claim to evidence map
Reviewer question list
Closure action plan

Who uses the output

certification manager assign closure actions from the exception register.
program manager use the map to locate source evidence.
DER decide what can proceed and what must wait.

How the work fits into the transaction or program

Use this review after engineering has a candidate package and before authority-facing release. It turns scattered records into a finite closure list. The page-specific framing is does the applicant response to an FAA issue paper or EASA Certification Review Item actually resolve the authority position with new substantiation. Evidence reviewed: the issue paper or CRI position and its stage or classification, the applicant response against each stated concern, the evidence cited in the response and whether it exists in the data package, and the closure status tracking across revisions. Failure modes include responses that restate the applicant position without addressing the authority. For issue paper cri response, the practical output is a defensible record of what was checked, what did not match, who owns the fix, and which issue remains outside the review boundary. The issue paper cri response evidence review scope is intentionally narrow: Get issue paper and CRI responses reviewed for substantiation gaps before they go back to the authority.. The Issue Paper Cri evidence question is tested against issue paper or cri position and not against a generic checklist copied from another page. The Response Evidence Review trigger is issue paper or cri issued on the program, so the review ranks gaps by decision impact instead of document volume. The Agreed Certification Basis searcher pattern is A certification manager with an open issue paper or CRI searching for how to structure a response that closes rather than escalates.. The Positions Backed Not evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Restatement Closure Audit exception logic separates missing artifacts from mismatched data because those findings move through different closure routes. The Closure Trace Baseline handoff is written for certification manager, with unresolved items preserved as decisions rather than softened into narrative prose. The deliverable stays anchored on issue paper and cri response evidence exception register, which makes the next reviewer able to reperform the path without rebuilding the file. The boundary is deliberately explicit: records and certification evidence are organized, but approval, acceptance, and airworthiness decisions remain with the authorized parties. The brief-specific angle is does the applicant response to an FAA issue paper or EASA Certification Review Item actually resolve the authority position with new substantiation. Evidence reviewed: the issue paper or CRI position and its stage or classification, the applicant response against each stated concern, the evidence cited in the response and whether it exists in the data package, and the closure status tracking across revisions. The failure pattern includes responses that restate the applicant position without addressing the authority concern, evidence cited that was never delivered, and stale response drafts circulating after the authority revised its position.

The governing intent remains Get issue paper and CRI responses reviewed for substantiation gaps before they go back to the authority.. The operating angle for this page is Decision: does the applicant response to an FAA issue paper or EASA Certification Review Item actually resolve the authority position with new substantiation. Evidence reviewed: the issue paper or CRI position and its stage or classification, the applicant response against each stated concern, the evidence cited in the response and whether it exists in the data package, and the closure status tracking across revisions.

Start with a single asset

Confirm each requirement maps to substantiating evidence.

Regulatory limits

EE organizes evidence and exceptions; it does not approve data, make compliance findings, determine airworthiness, or replace the applicant, designee, design organization, or authority.

What this review does not cover

Regulatory approval or acceptance
Design ownership or finding signature
Physical conformity inspection
Laboratory testing or manufacturing

Specific to this review

Configuration identity matters because evidence from another baseline may prove a different article, load, or installation.
A useful trail names the source record, revision, owner, and closure decision for each claim.
The exception list separates document-control cleanup from gaps that need engineering substantiation.
The finding pattern for this page is specific: responses that restate the applicant position without addressing the authority concern changes the strength of the certification argument.
The scope uses the Issue Paper Cri Response question as the control point, so the review stays tied to Issue paper or CRI issued on the program and the buyer decision behind it.
The evidence starts with Issue paper or CRI position and follows Evidence Review Agreed Certification references until every exception has a source location and a reason code.
The finding logic separates missing paperwork, conflicting status, stale revision data, and unsupported disposition because each class closes through a different owner.
The timing matters for certification manager: the output is useful only if the unresolved items are visible before acceptance, submittal, handback, or negotiation pressure fixes the sequence.
The boundary control keeps Basis Positions Backed Not questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
The handoff value comes from Issue paper and CRI response evidence exception register; it gives the next reviewer a precise map instead of another broad request for a better file.

Frequently asked questions

What makes this evidence review different from a general file audit?

The scope is tied to issue paper cri response and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block issue paper or cri issued on the program or can be closed later without changing the decision.

What evidence has to be available before this work starts?

The starting point is issue paper or cri position, the current status source, and any index or matrix that tells reviewers where the supporting artifact should live. Missing inputs are logged as findings rather than filled with assumptions.

Who decides whether an open item is acceptable?

The review explains what the evidence supports and gives certification manager a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
