DO-178C SOI-4 final package evidence review for DO-178C
This review is for avionics suppliers, Certification teams, Engineering teams responsible for DO-178C SOI-4 final package. It is triggered by sOI-4 audit scheduled. EE checks Software Accomplishment Summary claim by claim, SECI against the delivered build, open problem report list with safety-effect justifications, plus the governing plan or application, against DO-178C. Discrepancies include missing source records, mismatched configuration, unsupported assumptions, or SAS claims that differ from what earlier SOI findings established. Output includes DO-178C SOI-4 final package exception register, Claim to evidence map, Reviewer question list.
When this review is needed
The problem
File volume does not settle the question. The package must show why the evidence proves is the final software data package closed enough to pass the SOI-4 final certification review, especially where SAS claims that differ from what earlier SOI findings established.
What gets reviewed
- Review software Accomplishment Summary claim by claim against the configuration, installation, or claim under review.
- Compare sECI against the delivered build against the configuration, installation, or claim under review.
- Trace open problem report list with safety-effect justifications against the configuration, installation, or claim under review.
- Challenge final build demonstration records. against the configuration, installation, or claim under review.
What gets validated
- Pass check: software Accomplishment Summary claim by claim must match the released configuration and the claimed means of compliance.
- Configuration check: sECI against the delivered build must match the released configuration and the claimed means of compliance.
- Trace check: open problem report list with safety-effect justifications must match the released configuration and the claimed means of compliance.
- Rationale check: final build demonstration records. must match the released configuration and the claimed means of compliance.
Evidence normally required
- Controlled software Accomplishment Summary claim by claim
- Released sECI against the delivered build
- Signed open problem report list with safety-effect justifications
- Current final build demonstration records.
- Archived plan revision
- Supplier trace matrix
Common discrepancies
- Gap: sAS claims that differ from what earlier SOI findings established.
- Mismatch: oPRs with no analysis of operational effect.
- Unsupported claim: sCI part number that does not match the load actually delivered for conformity.
What is at stake
The cost is rework during authority-facing activity. Teams lose time when OPRs with no analysis of operational effect, because closure may touch configuration control and engineering rationale.
Move from findings to resolution
Identify gaps against the means of compliance.
How the work runs
Frame 178c Soi
Confirm the exact event, affected file set, buyer role, and decision standard before any software accomplishment summary claim by claim is treated as sufficient.
Trace Review Prep
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 Evidence Certification
Group exceptions by closure route: document retrieval, data correction, engineering disposition, authority response, or contractual decision.
Package Configuration Index
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
Who uses the output
- certification manager assign closure actions from the exception register.
- software lead 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
This review belongs at the point where draft evidence becomes a certification package. It prevents avoidable questions from becoming formal findings. The page-specific framing is is the final software data package closed enough to pass the SOI-4 final certification review. The review notes that evidence reviewed: the Software Accomplishment Summary claim by claim, the SCI and SECI against the delivered build, the open problem report list with safety-effect justifications, and the final build demonstration records. Failure modes include SAS claims that differ from what earlier SOI findings established, OPRs with no analysis of operational effect, and an SCI part number that does not match the load actually. For 178c soi final review, 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 do 178c soi 4 final review prep scope is intentionally narrow: Reconcile the final DO-178C data package before the SOI-4 review so approval is not delayed by closure gaps.. The 178c Soi Final evidence question is tested against software accomplishment summary claim by claim and not against a generic checklist copied from another page. The Review Prep Package trigger is soi-4 audit scheduled, so the review ranks gaps by decision impact instead of document volume. The Evidence Certification Sas searcher pattern is A certification manager weeks from SOI-4 searching for how to scrub the SAS, SCI, and open problem reports before the authority does.. The Configuration Index Open evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Problem Reports Reconciled exception logic separates missing artifacts from mismatched data because those findings move through different closure routes. The Closure Audit Baseline handoff is written for certification manager, with unresolved items preserved as decisions rather than softened into narrative prose. The deliverable stays anchored on do-178c soi-4 final package 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 is the final software data package closed enough to pass the SOI-4 final certification review. The review notes that evidence reviewed: the Software Accomplishment Summary claim by claim, the SCI and SECI against the delivered build, the open problem report list with safety-effect justifications, and the final build demonstration records. The failure pattern includes SAS claims that differ from what earlier SOI findings established, OPRs with no analysis of operational effect, and an SCI part number that does not match the load actually delivered for conformity.

The operating angle for this page is Decision: is the final software data package closed enough to pass the SOI-4 final certification review. The review notes that evidence reviewed: the Software Accomplishment Summary claim by claim, the SCI and SECI against the delivered build, the open problem report list with safety-effect justifications, and the final build demonstration records.

Regulatory limits
EE provides an evidence-quality assessment only. The work does not certify an article, sign a finding, approve a plan, or decide regulatory acceptance.
What this review does not cover
- Plan approval
- DER or DOA signature
- Conformity inspection
- Supplier selection
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: SAS claims that differ from what earlier SOI findings established changes the strength of the certification argument.
- The scope uses the 178c Soi Final Review question as the control point, so the review stays tied to SOI-4 audit scheduled and the buyer decision behind it.
- The evidence starts with Software Accomplishment Summary claim by claim and follows Prep Package Evidence 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 Sas Configuration Index Open questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from DO-178C SOI-4 final package 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 178c soi final review and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block soi-4 audit scheduled or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is software accomplishment summary claim by claim, 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.
