FDA Inspections
FDA PMA Pre-Approval Inspection
For a Class III device under PMA review, FDA inspects to confirm the quality system is in place and that what you make matches what you submitted. Unlike most FDA inspections, you know this one is likely because you filed the application, which makes the time before it valuable.
At a Glance
- Conducted by
- FDA investigators
- Tied to
- A pending PMA application
- Framework
- Compliance Program 7382.850 (PMA pre-approval/postmarket)
- Regulations
- 21 CFR Part 814 and the QMSR (21 CFR Part 820)
- Possible outcome
- Observations on Form 483; findings can affect the PMA decision
What It Is
A premarket approval application describes how the device is made: the facilities, methods and controls used in manufacturing. The pre-approval inspection checks those descriptions against reality and checks the quality system against the QMSR. Compliance Program 7382.850 covers PMA pre-approval inspections along with PMA postmarket inspections.
The investigator checks two things at once. First, the quality system: design controls, production and process controls, purchasing, CAPA and the rest, assessed against ISO 13485:2016 requirements plus the FDA-specific additions. Second, consistency: whether the manufacturing processes, specifications, suppliers and sites in the submission are the ones actually in use.
The findings matter beyond the inspection itself, because approval depends in part on manufacturing methods, facilities and controls that meet requirements. A gap between the submission and the shop floor can slow the review or require an amendment.
Who Conducts It
FDA investigators conduct the inspection, working from the manufacturing information in your PMA. Sites named in the application, including contract manufacturers performing manufacturing steps, may be inspected.
Your design team, process engineers and the people who wrote the manufacturing sections of the submission should be available, because many questions will compare what the application says with what the site does.
What Triggers It
- Submission of a PMA application for a Class III device
- Manufacturing sites, including contract manufacturers, named in the application
- After approval, PMA postmarket inspections under the same compliance program
What They Look At
Consistency With the Submission
Processes, parameters, specifications, suppliers and sites in production compared with the manufacturing sections of the PMA.
Design Controls and Design Transfer
Whether the design was transferred into production completely, with verified outputs and a design history that supports the submission.
Process Validation
Validation of special processes, including sterilization and packaging where relevant, matching the processes described in the application.
Risk Management
A current risk file that links clinical and design risks to the production controls that address them.
Purchasing and Supplier Controls
Controls over the suppliers and contract manufacturers named in the PMA, with quality agreements and evidence of oversight.
Readiness for Commercial Production
Whether the system can run at commercial scale, with complaint handling, MDR, CAPA and UDI ready to operate from launch.
How to Prepare
- 01
Reconcile the Application With the Floor
Walk the manufacturing sections of the PMA against current procedures, production records, equipment and suppliers. Log every difference.
- 02
Resolve Differences Deliberately
Decide with your regulatory team whether each difference means bringing the process back in line or updating the submission, and document the decision.
- 03
Close Out Design Transfer
Confirm the design history is complete and that production specifications trace to verified design outputs.
- 04
Confirm Validation Is Final
Validation protocols and reports should be approved, cover the commercial process and match the parameters in the submission.
- 05
Stand Up Postmarket Processes
Complaint handling, MDR, corrections and removals, tracking where it applies, and UDI should be ready to run even before product ships.
- 06
Rehearse the Comparison Questions
Practice answering 'is this what you described in the PMA?' with records, not assurances.
Common Pitfalls
- Process changes made after submission that were never reflected in the application.
- Validation completed on pilot equipment or a pilot line rather than the commercial one.
- Supplier lists in the PMA that no longer match the approved supplier list.
- Postmarket procedures written but never trained or tested because the product hasn't launched yet.
- Design transfer treated as a document handoff, with production running from engineering drawings outside document control.
How QMSAdvisor Helps
- An AI-assisted first pass that compares your manufacturing procedures, validations and supplier records with the manufacturing sections of your submission, with every discrepancy reviewed by an advisor.
- Advisor-reviewed findings that cite both the submission and the conflicting record, so regulatory and operations teams can decide how to resolve each one.
- A pre-approval scenario in the FDA Inspection Simulator, with document requests and interviews built around the submission.
- An action plan with owners, due dates and evidence requirements, sorted by severity.

Standards and Regulations Involved
Questions About the FDA PMA Pre-Approval Inspection
Will we know when a pre-approval inspection is coming?
You'll know one is likely because it's tied to your PMA, but FDA sets the timing. Start preparing when you submit, not when you hear from FDA.
Does an MDSAP audit replace the pre-approval inspection?
No. FDA accepts MDSAP audit reports in place of routine surveillance inspections, not pre-approval inspections.
What if our process changed after we submitted?
Any difference between the application and the actual process needs a decision: bring the process in line with the submission or update the submission. Work it through with your regulatory team, and keep the rationale on file.
Are contract manufacturers inspected too?
Sites performing manufacturing steps named in the application may be inspected. Make sure your contract manufacturers understand the parts of the submission that apply to them and are ready to host FDA.
Can inspection findings affect the PMA decision?
Yes. Approval depends in part on manufacturing methods, facilities and controls that meet requirements, so significant findings can affect the outcome. That's why the reconciliation work before the inspection is worth doing thoroughly.
