EMI/EMC test report evidence review for DO-160G

This review is for equipment suppliers, avionics suppliers, Engineering teams responsible for EMI/EMC test report. It is triggered by eMC test report acceptance. EE checks emissions, susceptibility results against the selected categories, test setup photos/description, plus the governing plan or application, against DO-160G. Discrepancies include missing source records, mismatched configuration, unsupported assumptions, or emissions passed with a shorter or better-bonded cable than the installation. Output includes EMI/EMC test report exception register, Claim to evidence map, Reviewer question list.

When this review is needed

A new article, software load, or installation is moving into certification review.
Quality control needs a repeatable list of ready and open records.
Internal teams need a supplier request list tied to evidence gaps.
The buyer wants a defensible package before committing the claim.

The problem

Certification risk sits in the gap between the claimed basis and the records in the folder. With EMI/EMC test report, emissions passed with a shorter or better-bonded cable than the installation can stay hidden until the exact source record is requested.

What gets reviewed

Review emissions against the configuration, installation, or claim under review.
Compare susceptibility results against the selected categories against the configuration, installation, or claim under review.
Trace test setup photos/description against the configuration, installation, or claim under review.
Challenge its representativeness against the configuration, installation, or claim under review.
Reconcile margin against limits against the configuration, installation, or claim under review.
Confirm any anomalies against the configuration, installation, or claim under review.

What gets validated

Pass check: emissions must match the released configuration and the claimed means of compliance.
Configuration check: susceptibility results against the selected categories must match the released configuration and the claimed means of compliance.
Trace check: test setup photos/description must match the released configuration and the claimed means of compliance.
Rationale check: its representativeness must match the released configuration and the claimed means of compliance.
Closure check: margin against limits must match the released configuration and the claimed means of compliance.

Evidence normally required

Controlled emissions
Released susceptibility results against the selected categories
Signed test setup photos/description
Current its representativeness
Archived margin against limits
Supplier any anomalies

Common discrepancies

Gap: emissions passed with a shorter or better-bonded cable than the installation.
Mismatch: susceptibility margins that vanish at aircraft level.
Unsupported claim: undocumented setup deviations.

What is at stake

A weak package can convert a planned review into a long question log. If susceptibility margins that vanish at aircraft level, the program may need new evidence before the claim can proceed.

Move from findings to resolution

Identify gaps against the means of compliance.

How the work runs

Frame Emi Emc

Confirm the exact event, affected file set, buyer role, and decision standard before any emissions is treated as sufficient.

Trace Report Review

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 160g Certification

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

Package Susceptibility Setup

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

EMI/EMC test report exception register
Claim to evidence map
Reviewer question list
Closure action plan

Who uses the output

EMC engineer assign closure actions from the exception register.
qualification engineer use the map to locate source evidence.
certification liaison decide what can proceed and what must wait.

How the work fits into the transaction or program

Does the EMI/EMC test report (DO-160 Sections 19-21) actually support the installation, because EMC results are dominated by the test setup: cable lengths, grounding, bonding, and whether the tested configuration matches the fielded harness. The evidence set centers on the emissions and susceptibility results against the selected categories, the test setup photos/description and its representativeness, margin against limits, any anomalies and their disposition, and traceability to the qualified configuration. The likely weak points are emissions passed with a shorter or better-bonded cable than the installation, susceptibility margins that vanish at aircraft level, and undocumented setup deviations; Distinct from the generic do-160-report evidence pages, which are buyer-tagged category reviews; this is the EMC-specific report critique. The output gives the EMC engineer a cleanup register for EMI/EMC test report before EMC test report acceptance.

Start with a single asset

Confirm requirements trace through verification.

Regulatory limits

The output supports applicant decision making and authority discussions. It does not replace required approvals, designee findings, conformity activity, or airworthiness determinations.

What this review does not cover

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: emissions passed with a shorter or better-bonded cable than the installation changes the strength of the certification argument.
The scope uses the Emi Emc Test Report question as the control point, so the review stays tied to EMC test report acceptance and the buyer decision behind it.
The evidence starts with Emissions and follows Review Evidence 160g 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 EMC engineer: 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 Emissions Susceptibility Setup Decides questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
The handoff value comes from EMI/EMC test report 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 emi emc test report and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block emc test report acceptance or can be closed later without changing the decision.

What evidence has to be available before this work starts?

The starting point is emissions, 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 emc engineer a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
