Conformity records
Conformity records evidence review for equipment suppliers
This review examines the conformity records that tie a supplier's test results to the article they were run on. It confirms each test or qualification article was identified, built to a controlled configuration, and eligible for the test at the time it was run, so the results credited to certification actually belong to a known build. An engineer familiar with conformity and article identity runs it before submittal, in a finding response, or when a change alters which article a result applies to. You receive a gap list of results that do not tie to a controlled article, an evidence map, and a closure sequence for engineering leadership.
When this review is needed
- Test articles were built and modified across a campaign and it is unclear which configuration each result belongs to.
- A finding asks the supplier to show a test article was conformed before the test that produced a credited result.
- A result is being reused from an earlier article whose eligibility for this certification is unconfirmed.
- A change was made to an article mid-campaign and the results before and after need to be attributed correctly.
The problem
Test results are only as good as the article behind them, and that link is the first thing to blur under schedule pressure. An article gets a quick modification to keep testing moving, a serialized part is swapped, a conformity inspection is deferred until after a run. Each shortcut feels harmless in the lab, but it leaves a result that cannot be firmly attributed to a controlled build when the records are examined later.
What gets reviewed
- Confirmation that each test article was identified by serial or part configuration
- Check that a conformity inspection established the article's configuration before the test
- Read of eligibility so each article was in a state permitted for the test it underwent
- Attribution of each credited result to the specific article and configuration that produced it
- Review of mid-campaign article changes and how results were split around them
- Identification of results not tied to any controlled article or conformed build
What gets validated
- Every credited test result names the article and configuration it was produced on
- A conformity record establishes the article's configuration before the test that used it
- Each article was eligible for the test performed at the time it was run
- Article changes during the campaign are reflected in how results are attributed
- Reused results identify their original article and its eligibility for this certification
Evidence normally required
- Conformity inspection records for each test and qualification article
- Article identification data, including serial numbers and as-built configuration
- The test reports whose results are credited to certification
- The configuration or change history of each article across the campaign
- Any authority conformity requests or witnessing arrangements on record
Common discrepancies
- Results credited to an article whose conformity inspection postdates the test
- An article modified mid-campaign with results attributed as if the build never changed
- Reused test data from an article whose eligibility for this program is unestablished
- Test articles identified only by an informal label that does not tie to a controlled part
What is at stake
A test result that does not tie to a conformed article is a result the certification cannot rely on, no matter how good the data is. Closing the gap can mean re-conforming an article that has since changed or repeating the test on a properly conformed build, both of which cost an article and a lab slot late in the program. Until then, the requirement the result was meant to close stays open.
Move from findings to resolution
Identify gaps against the means of compliance.
How the work runs
Identify each article
Establish the serial and as-built configuration of every test article the results are credited to.
Confirm conformity timing
Check that a conformity record predates each test and describes the configuration the test used.
Attribute the results
Tie each credited result to its article and account for any mid-campaign change that split the data.
Sequence the closures
Order re-conformity and retest by article availability so items needing a new build start first.
What the buyer receives
- A gap list of results that do not tie to a conformed, eligible article
- An evidence map linking each credited result to its article, configuration, and conformity record
- A closure sequence ordering re-conformity or retest by article availability
Who uses the output
- Engineering leadership deciding which results need re-conformity or retest before submittal
- Certification leads defending the article-to-result link under authority review
- Test and quality engineers reconstructing article configuration and conformity records
How the work fits into the transaction or program
Conformity records are the bridge between the physical test article and the paper certification, so this review sits alongside the configuration management review that controls the article's configuration on paper. Together they confirm a credited result belongs to a known build, which the verification trace review then relies on when it counts that result as closing a requirement.
Start with a single asset
Confirm requirements trace through verification.
Jurisdiction-specific considerations
The FAA works conformity through its inspection and delegated conformity processes, while EASA frames it within the design organization's arrangements and part conformity, and each may witness or request conformity differently. This review notes where an article's conformity would satisfy one authority's expectation but leave a question for the other, particularly for reused or foreign-tested articles.
Regulatory limits
This review checks whether test results tie to a conformed, eligible article. It performs no conformity inspection, makes no airworthiness determination, and does not approve any article or result. Conformity determinations and their acceptance rest with the authority and its inspectors or delegates.
What this review does not cover
- Performing conformity inspections of the test articles
- Building, modifying, or re-conforming the articles themselves
- Judging the technical validity of the test results as data
Specific to this review
- A test result is only as certifiable as the article behind it, so pristine data on an unconformed article closes nothing.
- The riskiest records are the mid-campaign modifications, because a single undocumented change can split a run into results that belong to two different builds.
- Re-conforming an article that has since changed is often impossible, which turns a records gap into a retest that needs a new article.

Frequently asked questions
The test data is solid. Why does conformity of the article matter?
Because certification credit attaches to a controlled article, not to raw data. If the article was not conformed before the test, or was modified in a way the records do not capture, the results cannot be attributed to a known build. This review confirms the article-to-result link so the data you produced can actually be credited.
