FAQ

What certifications are required for airplane parts?

Airplane parts require different certifications based on application. Commercial aircraft parts need FAA approval through PMA or OEM certification. Quality management relies on AS9100D certification for aerospace-specific processes. Defense-related components require ITAR registration for export control compliance. Parts must meet airworthiness standards and maintain complete traceability throughout manufacturing.

How do AS9100D and FAA-PMA certifications differ?

AS9100D is a quality management standard that ensures consistent manufacturing processes, risk management, and configuration control across aerospace production. FAA-PMA is a design and production approval that allows manufacturers to produce specific aircraft replacement parts that meet airworthiness standards. AS9100D governs how manufacturers build aerospace parts. PMA governs what manufacturers can produce for aircraft applications.

Can contract manufacturers scale from prototype to high-volume production?

Leading contract manufacturers such as Precision Advanced Manufacturing provide seamless scalability from prototype through multi-shift production. Key factors include flexible manufacturing systems, certified quality processes, adequate facility capacity, and experienced program management. Successful scaling maintains the same quality standards validated during prototyping while adding efficient production workflows.

Is ITAR registration required for all US aerospace manufacturing?

ITAR registration applies only to defense-related aerospace components and technology. Commercial aviation parts typically do not require ITAR unless they have dual-use applications or contain controlled technology. Many aerospace manufacturers still maintain ITAR registration to serve both commercial and defense markets, which supports flexible program coverage.

What precision tolerances are typical for aerospace airplane parts?

Aerospace airplane parts typically require tolerances ranging from ±0.001″ to ±0.010″ depending on application. Critical flight components such as engine parts often demand ±0.0005″ or tighter tolerances. Structural components may allow ±0.005″ to ±0.010″ tolerances. Advanced CNC machining and precision fabrication processes support consistent achievement of these demanding specifications with full traceability and documentation.
