Conformity
Conformity-evidence readiness review for test and inspection
A conformity-evidence readiness review checks whether the article presented for test or inspection can be shown to match the approved configuration it was built to. It is used by avionics, equipment, and modification teams before a conformity inspection or a witnessed test. It reviews the build and configuration records, the part and serial data, the conformity statements, and the link from the test article back to the released drawings. You receive a conformity readiness assessment, a list of configuration mismatches, and the records needed to support the inspection request.
When this review is needed
- A conformity inspection is scheduled and the team needs to know the article and its paperwork agree before the inspector arrives.
- A test article was built against drawings that have since been revised, and the build state has to be reconciled with what was released.
- A witnessed test is approaching and the test setup, software load, and hardware standard must be pinned to a defined configuration.
- An earlier conformity attempt was rejected on configuration and the team wants the gaps closed before re-presenting.
The problem
Conformity turns on whether the thing in front of the inspector is provably the thing on the drawings. Engineering changes, deviations, and waivers accumulate during build, and the records that should capture them lag behind the hardware. When the part standard, software load, or modification state cannot be tied to the released configuration, the inspection cannot conclude.
What gets reviewed
- The released configuration the article was meant to be built to
- Build records, travelers, and the as-built part and serial data
- Deviations and waivers raised during build and their disposition
- The conformity statements and the inspections they reference
- The software load and hardware standard installed on the test article
- The link from the test setup to a defined and recorded configuration
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Identify what is missing against the means of compliance.
What gets validated
- The as-built configuration reconciles to the released drawings and parts list
- Each deviation and waiver is recorded, dispositioned, and reflected in the conformity record
- Part numbers and serial numbers on the article match the build documentation
- The installed software load and hardware standard are identified and recorded
- Each conformity statement references inspections that were actually performed
- The test configuration is defined precisely enough to repeat
- Open build items are visible rather than absent from the record
Evidence normally required
Common discrepancies
- As-built hardware that differs from the released drawing without a recorded deviation
- Conformity statements citing inspections that have no supporting record
- Software loads on the article that are not identified in the configuration data
- Deviations raised during build but never dispositioned or closed
- Serial-number mismatches between the article and its build paperwork
- A test setup described too loosely to reproduce for a witnessed run
What is at stake
A rejected conformity holds the whole test campaign. Witnessing slots are rebooked, the article sits idle, and any data taken against an unconfirmed configuration may have to be repeated once the build state is finally pinned down.
How the work runs
Pin the baseline
Confirm the released configuration the article was built to, including software and hardware standards.
Reconcile as-built
Compare build records and as-built data to the released drawings and parts list.
Disposition the changes
Check that every deviation and waiver is recorded, dispositioned, and reflected in the conformity record.
Assemble the request
Package the readiness assessment and supporting records for the inspection.
What the buyer receives
- A conformity readiness assessment for the article and its records
- A list of configuration mismatches and undispositioned deviations
- A records package supporting the conformity inspection request
Who uses the output
- Quality and conformity leads requesting the inspection
- Test engineers pinning the article configuration
- Certification leads confirming the test basis
How the work fits into the transaction or program
The review sits just ahead of a conformity inspection or witnessed test, where the question is build-to-drawing agreement rather than requirement coverage. It complements a traceability or evidence review by confirming the physical article and its records line up before time-bound witnessing is committed.

Regulatory limits
Endeavor Elements reviews the applicant's conformity evidence. It does not perform the conformity inspection, make a conformity finding for the authority, or certify the article. Those actions belong to the authority or its delegate.
What this review does not cover
- Performing or witnessing the conformity inspection
- Making a conformity finding or issuing any approval
- Building or reworking the test article
Specific to this review
- Conformity is a build-to-design question: it tests whether the article provably matches the released configuration, separate from whether the design itself is compliant.
- Deviations and waivers raised during build are a frequent source of conformity rejection when their disposition never reaches the conformity record.
- A software load or hardware standard that is not identified in the configuration data can stall an inspection even when the hardware is correct.
- A test configuration that cannot be reproduced from the record undermines the data taken against it, so the setup is reviewed for repeatability, not just presence.

Frequently asked questions
Does a conformity review confirm the design is compliant?
No. It confirms the article matches the approved configuration it was built to. Whether that design meets the requirements is a separate question handled by evidence and traceability reviews.
