ARP4754B evidence
Safety program plan review for new development program kickoff
For safety managers, systems engineering managers, and program managers, this page is used this page when New development program kickoff depends on records that have moved across revisions, suppliers, or workstreams. EE checks safety program plan, development plan, FHA schedule, PSSA and SSA plan 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
- New development program kickoff has created a gate where document titles are no longer enough.
- Leaders need a ranked list of plan 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 safety program plan still agrees with PSSA and SSA plan. That uncertainty burns review time when a sampled citation fails.
What gets reviewed
- Inventory safety program plan and record its source, owner, and controlled revision.
- Match development plan against the current baseline and the applicable plan language.
- Follow FHA schedule through downstream reports, summaries, and closure notes.
- Flag PSSA and SSA plan when it refers to a superseded configuration or unresolved deviation.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 safety program plan and PSSA and SSA plan; 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- Downstream documents are sampled for references that still point to superseded material.

Common discrepancies
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 fits into the transaction or program
This work sits upstream of authority or delegate review. It lets program leaders see whether the evidence package is ready to be sampled or whether source records need another closure cycle. The page-specific framing is does the safety program plan sequence FHA, PSSA, SSA, and CCA so their outputs can still influence design, or is safety scheduled as documentation after the fact. The review notes that evidence reviewed: scope and timing of each safety analysis, interfaces to the development plan and item DALs, criteria for updating analyses after change, and responsibilities across suppliers. Failure modes include SSA scheduled after design freeze so findings cannot change anything, no trigger for re-running analyses after modification, and. For safety program plan 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 safety program plan review scope is intentionally narrow: Review the safety program plan for sequencing and scope gaps before the safety process becomes retrospective paperwork.. The Safety Program Plan evidence question is tested against program safety plan and not against a generic checklist copied from another page. The Review New Development trigger is new development program kickoff, so the review ranks gaps by decision impact instead of document volume. The Kickoff Arp4754b Evidence searcher pattern is A safety manager standing up a program searching for what a safety program plan must schedule and where programs get it wrong.. The Activities Scheduled Design evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Freezes Sequencing 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 safety manager, with unresolved items preserved as decisions rather than softened into narrative prose. The deliverable stays anchored on gap log for safety program plan review, 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 safety program plan sequence FHA, PSSA, SSA, and CCA so their outputs can still influence design, or is safety scheduled as documentation after the fact. The review notes that evidence reviewed: scope and timing of each safety analysis, interfaces to the development plan and item DALs, criteria for updating analyses after change, and responsibilities across suppliers. The failure pattern includes SSA scheduled after design freeze so findings cannot change anything, no trigger for re-running analyses after modification, and supplier safety data arriving in formats the integrator cannot use.

The governing intent remains Review the safety program plan for sequencing and scope gaps before the safety process becomes retrospective paperwork.. The operating angle for this page is Decision: does the safety program plan sequence FHA, PSSA, SSA, and CCA so their outputs can still influence design, or is safety scheduled as documentation after the fact. The review notes that evidence reviewed: scope and timing of each safety analysis, interfaces to the development plan and item DALs, criteria for updating analyses after change, and responsibilities across suppliers.

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
- Design approval
- Regulatory acceptance decisions
- Laboratory testing or retesting
- Acting as DER, DAR, ODA unit member, or authority
Specific to this review
- PSSA and SSA plan 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 Safety Program Plan Review question as the control point, so the review stays tied to New development program kickoff and the buyer decision behind it.
- The evidence starts with program safety plan and follows New Development Kickoff Arp4754b 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 safety 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 Evidence Activities Scheduled Design 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 safety program 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 safety program plan 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 new development program kickoff or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is program safety 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 safety manager a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
