Inspection & Metrology for Aerospace — FAQs
The questions engineering and procurement teams ask most often before a first quote.
What aerospace components are well suited to Inspection & Metrology?
Inspection & Metrology suits documented dimensional verification with CMM and traceable metrology equipment. Typical aerospace parts include Brackets, Ribs, Mounts and supports, Bushings and precision hardware.
What tolerances are typical for aerospace inspection and metrology?
Northline holds Traceable to NIST as a typical envelope on Inspection & Metrology, with tighter callouts held on qualified features and reviewed against process capability during quoting.
Which aerospace materials can Northline inspect?
Common aerospace materials include Aluminum 6061 / 7075 / 2024, Titanium Ti-6Al-4V, Stainless 304 / 316 / 17-4 PH, Inconel 625 / 718. Grade selection and heat/lot traceability are maintained; alternates are reviewed during quoting.
Can Northline provide First Article Inspection documentation?
Yes. AS9102-format First Article Inspection reports are available on request. Northline is ISO 9001:2015, AS9100D, and ITAR registered.
Can you support both prototype and repeat aerospace production?
Yes. The same setups used for prototype and first-article carry into repeat production, so geometry and inspection results carry forward without a process change.
How do you control aerospace-specific engineering considerations on Inspection & Metrology?
Feature-level verification on positional and profile callouts. Datum strategy, inspection frequency, and fixturing are reviewed during quoting against the specific aerospace drawing requirements.
