Personnel qualificationNot applicable
How is this computed?
Certificate credit = validity × evidence × issuer legitimacy × completeness. Each component earns points; components that do not apply to this company are removed from the denominator. Score = 100 × points earned ÷ applicable points. A critical flag lowers the band by one level. Calibration records and company-declared quality-system details are not captured yet and count as not demonstrated.
Computed 23 Oct 2026
Quality flags
Computed automatically from the published data. A flag is a question to ask the supplier, not a verdict.
WarningServes Aerospace without the sector quality standard (AS9100 / ISO 13485 / IATF 16949)
