DO-160G evidence

Environmental qualification test plan review for qualification test planning

qualification engineer, certification liaison, test lead use this page when Qualification test planning depends on records that have moved across revisions, suppliers, or workstreams. EE checks DO-160 test plan, category selection worksheet, test sequence, functional check procedure against the applicable basis, plan language, and source records. Findings are written as evidence gaps, not approval decisions. The deliverable is a ranked discrepancy log with the evidence trail needed for closure.

When this review is needed

Qualification test planning has created a gate where document titles are no longer enough.
Program leaders need a ranked list of environmental qualification test plan review blockers rather than another unfiltered file dump.
The review notes that evidence was copied from earlier work and its applicability must be tested.
Authority, DER, ODA, or internal reviewers are expected to sample the record trail.

The problem

Teams usually know the files exist, but they do not always know whether DO-160 test plan still agrees with functional check procedure. That uncertainty burns review time when a sampled citation fails.

What gets reviewed

Inventory DO-160 test plan and record its source, owner, and controlled revision.
Match category selection worksheet against the current baseline and the applicable plan language.
Follow test sequence through downstream reports, summaries, and closure notes.
Flag functional check procedure when it refers to a superseded configuration or unresolved deviation.
List missing source records needed before reviewers can rely on the package.

What gets validated

A cited record passes only if its identifier, title, and revision match the controlled index.
Configuration alignment is tested between DO-160 test plan and functional check procedure; conflicting serials, drawings, or baselines fail.
The review notes that evidence type is checked against the claim, so analysis cannot silently replace a promised test or inspection.
Open exceptions fail the gate when they have no owner, due path, or technical disposition.
Downstream documents are sampled for references that still point to superseded material.

Evidence normally required

DO-160 test plan
category selection worksheet
test sequence
functional check procedure
pass fail criteria
article configuration record

Common discrepancies

Failure modes: categories chosen without installation input.
a sequence that masks a failure (e.g. wrong order of thermal and vibration).
criteria too loose to be meaningful.

What is at stake

Late discovery turns a records problem into a program problem. Reviewers may pause sampling, ask for a corrected baseline, or require new evidence before the package can move forward.

How the work runs

Frame Environmental Qualification

Confirm the exact event, affected file set, buyer role, and decision standard before any do-160 test plan is treated as sufficient.

Trace Plan 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 Evidence

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

Package Fixed Lab

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

Gap log for environmental qualification test plan review
Cross reference table
Document retrieval list
Disposition worksheet
Submittal readiness note

Who uses the output

qualification engineer decides which exceptions block the next gate.
certification liaison updates the plan, matrix, or report index.
test lead tracks owner responses through closure.

How the work fits into the transaction or program

Does the DO-160 qualification test plan lock the right categories, levels, sequence, and pass/fail criteria before the equipment goes to the lab, because a wrong plan produces a full report that proves the wrong thing. The evidence set centers on the environmental-category selection tied to the installation, the test sequence and any pre/post functional checks, the pass/fail and performance criteria per section, the article configuration and its conformity, and the mapping to the applicable TSO/standard; Failure. The likely weak points are categories chosen without installation input, a sequence that masks a failure (e.g; wrong order of thermal and vibration), and criteria too loose to be meaningful; Distinct from the live environmental-qualification-evidence-review and qualification-test-report-review, which review the results, not the plan. The output gives the qualification engineer a cleanup register for Environmental qualification test plan review for qualification test planning before qualification test planning.

Regulatory limits

The review is an evidence and consistency check only. EE does not approve data, accept certification credit, make airworthiness determinations, or act for FAA, EASA, a DER, a DAR, or an ODA unit member.

What this review does not cover

Specific to this review

functional check procedure is often where stale evidence surfaces first, because reports preserve old titles long after plans change.
A complete index is weaker than a resolved index; the review asks whether each citation can actually be used.
Supplier or lab records need the same baseline discipline as internal certification data.
A discrepancy should name the blocked decision, not merely the document where the problem was found.
The scope uses the Environmental Qualification Test Plan question as the control point, so the review stays tied to Qualification test planning and the buyer decision behind it.
The evidence starts with DO-160 test plan and follows Review Planning 160g Evidence 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 qualification 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 Categories Fixed Lab 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 Gap log for environmental qualification test plan review; 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 environmental qualification test plan and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block qualification test planning or can be closed later without changing the decision.

What evidence has to be available before this work starts?

The starting point is do-160 test plan, 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 qualification engineer a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
