Which Inspection Level Does Your Project Need?

Your inspection optionBest fitWhat to agree
Standard InspectionGeneral production partsAgreed visual and dimensional checks.
CMM / Full DimensionalComplex geometry or tight tolerancesA defined measurement scope and dimensional report.

FREQUENTLY ASKED QUESTIONS

Your Quality Assurance Questions, Answered.

Can you provide FAI reports?

Yes, first article inspection support can be included in your reviewed scope. Send your drawing, revision, required report format and sample quantity. Confirm any AS9102-style requirement before ordering; a report format does not imply aerospace certification.

Do you support PPAP?

PPAP support is reviewed for your part and customer requirements. Send your submission level, templates, required elements and approval timing so the scope and feasibility can be confirmed in your quotation.

Can you provide material certificates?

Specify MTR, COA or other material documentation at RFQ. Record availability depends on the material, source and agreed traceability scope; confirm what will be supplied before your order.

How do you control drawing revisions?

You identify the controlled drawing and revision for the order. Agree changes in writing and confirm which revision applies to inspection records, samples and repeat production.

Can you inspect critical dimensions with CMM?

CMM inspection can be reviewed for appropriate dimensions and GD&T. Measurement access, datums, part geometry and required tolerance determine the suitable method. Mark your CTQs and request the report scope.

What inspection documentation is available?

You can request dimensional reports, FAI evidence, material certificates, a CoC, lot or revision records, and agreed PPAP elements. The reviewed quotation confirms the documents included in your order.

Can you support lot traceability?

Request the level of lot identification and record linkage your program needs. Agree the relevant material, production, inspection and shipment records before production.

How do you handle nonconforming parts?

Agree the review and escalation process with your team. Suspect parts should be identified and contained, with disposition or corrective action reviewed against your approved requirements. Report an issue with part, order, lot and evidence so the team can investigate.
