Certification plan
Certification plan evidence review for qualification test teams
A certification plan evidence review checks that the plan's stated basis, affected areas, and review commitments are matched by the data the team can actually deliver. It is run by or for a qualification test team before submittal, a finding response, or a change that alters the certification approach. The review compares what the plan promised against the evidence in hand and flags commitments the data package does not yet meet. You receive a gap list keyed to the plan's commitments, an evidence map from commitment to record, and a closure sequence for the test lead.
When this review is needed
- A certification plan is set and the team wants to confirm the data package can meet what it promised.
- The certification approach shifted mid-program and the plan may commit to work the data no longer reflects.
- An authority finding questioned whether a plan commitment was actually delivered in the package.
- The affected areas were scoped early and a design change may have widened them beyond the plan.
The problem
The certification plan is a promise made early, before most of the evidence exists, and the program rarely closes the loop back to it. The plan commits to a set of review milestones, names affected areas, and fixes a basis, then the data package drifts as the design and schedule move. By submittal the plan can promise coverage the package never produced, and an authority reading the plan against the data is the first to notice.
What gets reviewed
- The stated certification basis reconciled to the basis the evidence was produced against
- Affected areas in the plan checked against the areas the data package actually addresses
- Review and involvement commitments reconciled to what was delivered
- The committed means of compliance checked against the evidence types produced
- Plan assumptions checked against how the program actually ran
- Design changes checked for corresponding updates to the plan's scope
What gets validated
- The basis stated in the plan matches the basis the evidence was produced against
- Every affected area named in the plan is addressed by the data package
- Each review or involvement commitment in the plan was delivered
- The means of compliance committed in the plan match the evidence types produced
- A change that widened the affected areas is reflected in the plan's scope
Evidence normally required
- The certification plan with its basis, affected areas, and commitments
- The data package the team intends to submit
- The certification basis the evidence rests on
- The compliance matrix showing which commitments were met
- Change records that altered the certification approach or scope
Common discrepancies
- An affected area named in the plan that the data package never addressed
- A review commitment in the plan with no record that it was delivered
- A means of compliance the plan committed that the evidence does not reflect
- A design change that widened scope without an update to the plan
What is at stake
A plan that promises more than the package delivers reads as a program that lost track of its own commitments, and an authority that finds the gap can question whether the certification approach was followed. Commitments the data does not meet either force late work to catch up or an amended plan negotiated under time pressure, both of which cost schedule.

How the work runs
Read the promises
Extract the basis, affected areas, and review commitments the plan actually made.
Match to the package
Reconcile each commitment against the evidence the team can deliver at submittal.
Find the shortfalls
Flag commitments the data does not meet and scope a design change widened.
Sequence the closeout
Order the work or plan amendments needed to reconcile the plan and the package.
What the buyer receives
- A gap list keyed to plan commitments the data package does not meet
- An evidence map from each commitment to the record that delivers it
- A closure sequence ordering the shortfalls by dependency and effort
Who uses the output
- Test leads confirming the package meets the plan before submittal
- Certification leads answering a finding on an undelivered commitment
- Engineering owners closing scope a design change added to the plan
How the work fits into the transaction or program
The review closes the loop the program opened when it wrote the plan, checking at submittal that the promises made early are matched by the evidence in hand. Its gap list drives the work or the plan amendment needed to reconcile the two, and its evidence map ties each commitment to the record that satisfies it.

Jurisdiction-specific considerations
FAA and EASA both work from an agreed certification plan and each sets its own expectations for involvement and review milestones. The review notes where the plan satisfies one authority's involvement structure and where the other would expect the milestones or the affected-area definition to be framed differently.
Regulatory limits
The review checks the plan against the deliverable evidence. It does not agree the plan with an authority, accept the certification approach, or make a compliance determination.
What this review does not cover
- Authoring or negotiating the certification plan
- Agreeing the plan or the basis with an authority
- Determining compliance of the certified product
Specific to this review
- The plan is written before the evidence exists, so it is the one deliverable the program almost never checks itself back against.
- Affected areas are scoped early and a later design change is the usual reason the plan promises less coverage than the finished design needs.
- Review and involvement commitments are easy to leave undelivered, because they are agreed up front and rarely tracked to a closing record.

Frequently asked questions
What if the plan promised more than we can now deliver?
The review flags each commitment the package does not meet and separates those that added work can close from those that call for an amended plan agreed with the authority. Reconciling the plan before submittal is cheaper than explaining the gap in a finding response.
