What is the primary objective of AS9100?

AS9100's primary objective is to establish a quality management system (QMS) for aviation, space, and defense organizations that ensures product safety, configuration integrity, and supply chain reliability. It builds on ISO 9001:2015 with over 100 aerospace-specific requirements, including Clause 8.1.2 configuration management, 8.1.3 product safety, and 8.1.4 counterfeit parts prevention, to mitigate risks in high-consequence environments.

Who is legally or professionally required to comply with AS9100?

AS9100 applies to organizations that design, develop, manufacture, or service aviation, space, and defense products. Major OEMs and primes require certification as a supplier condition; it covers manufacturers, material suppliers, design centers, and quality support organizations, with 96% of certified entities under 500 employees per AAQG data.

Does AS9100 require an external audit or third-party certification?

Yes, AS9100 mandates third-party certification through accredited bodies via a two-stage audit process. Stage 1 assesses documentation readiness; Stage 2 verifies implementation effectiveness, followed by annual surveillance audits and recertification every three years, with visibility in IAQG's OASIS database.

How often should an assessment for AS9100 be performed?

AS9100 requires internal audits at planned intervals per Clause 9.2, with external surveillance audits annually and full recertification every three years. Assessments must cover high-risk areas like Clause 8 operations, using competent auditors to evaluate process effectiveness and nonconformities.

What are the consequences of non-compliance with AS9100?

Non-compliance with AS9100 risks certification suspension, loss of OEM supplier approval, and exclusion from OASIS. It leads to major nonconformities requiring 60-90 day corrective actions, potential contract termination, increased quality escapes, and safety incidents from failures in configuration or counterfeit controls.

Can AS9100 be mapped to other international frameworks?

Yes, AS9100D aligns with ISO 9001:2015's Annex SL 10-clause structure (Clauses 4-10), enabling integrated management systems. It shares PDCA cycles, risk-based thinking (Clauses 6.1, 8.1.1), and performance evaluation, facilitating mapping while retaining aerospace additions like product safety.

What is the first step to begin implementing AS9100?

The first step is conducting a gap analysis against AS9100D clauses to identify compliance gaps and define QMS scope per Clause 4.3. Engage cross-functional teams to map processes, risks, and non-applicabilities, producing a prioritized remediation plan before documentation or training.

What is the primary objective of EN 1090?

EN 1090 ensures controlled execution and conformity assessment of structural steel and aluminium components for CE marking under the Construction Products Regulation (CPR). It comprises EN 1090-1 (conformity assessment via certified Factory Production Control (FPC) and Declaration of Performance (DoP)), EN 1090-2 (technical requirements for steel structures including welding, tolerances, and inspection), and EN 1090-3 (parallel requirements for aluminium). Risk-based Execution Classes (EXC1–EXC4) scale requirements based on consequence class (CC1–CC3), service category (SC1–SC2), and production category (PC1–PC2), ensuring performance constancy for load-bearing components in construction works.

Who is legally or professionally required to comply with EN 1090?

Manufacturers of load-bearing steel and aluminium structural components and kits for permanent incorporation in EU/EEA construction works must comply with EN 1090 to affix CE marking. This includes fabricators, welding shops, and steelwork contractors supplying to buildings, bridges, or industrial structures. Compliance is mandatory under CPR for market placement; non-structural or non-metallic elements are excluded. Execution Class determination dictates capability needs, with EXC2 as default if unspecified.

Does EN 1090 require an external audit or third-party certification?

Yes, EN 1090-1 mandates third-party certification of the Factory Production Control (FPC) system by a notified body under AVCP systems 2+. This involves initial inspection of the factory/FPC, review of Initial Type Testing (ITT) or Initial Type Calculation (ITC), and issuance of a certificate enabling CE marking and DoP. Ongoing surveillance audits ensure continued conformity, with frequency tied to execution class.

How often should an assessment for EN 1090 be performed?

EN 1090 requires initial certification followed by continuous surveillance audits by the notified body, typically annually after the first year. Frequency follows EN 1090-1 Table B.3, scaled by execution class and prior performance. Manufacturers must conduct internal audits routinely, with FPC records maintained permanently to demonstrate constancy of performance.

What are the consequences of non-compliance with EN 1090?

Non-compliance with EN 1090 prevents lawful CE marking, risking market withdrawal, certificate suspension, and CPR enforcement actions. Notified bodies publicly report suspensions for major non-conformities; manufacturers face product recalls, fines, civil liability for failures, and exclusion from EU tenders. Poor traceability or welding controls often trigger these.

Can EN 1090 be mapped to other international frameworks?

No, EN 1090 FAQs focus solely on its standalone requirements under CPR for CE marking of structural metal components. (Independent per instructions.)

What is the first step to begin implementing EN 1090?

Conduct a product scope and execution class assessment to confirm applicability and determine EXC1–EXC4 based on consequence, service, and production categories. Default to EXC2 if unspecified, then perform gap analysis of current FPC against EN 1090-1, prioritizing welding coordination and traceability.
