What is the primary objective of **AS9120B**?

**AS9120B establishes quality management system requirements for organizations that procure, store, split, and resell aerospace parts without altering product characteristics.** Built on ISO 9001:2015’s 10-clause structure, it adds over 100 aerospace-specific controls targeting distribution risks like loss of traceability, counterfeit parts infiltration, documentation errors, and weak external provider oversight. The standard ensures chain-of-custody integrity through operational controls in Clause 8, including identification/traceability (8.5.2), counterfeit prevention (8.1.4), configuration management (8.1.2), and preservation (8.5.4).

Who is legally or professionally required to comply with **AS9120B**?

**AS9120B applies to stockist distributors, pass-through distributors, and organizations performing batch splitting in aviation, space, and defense supply chains.** It targets entities that purchase, store, and resell parts without modifying conformity, excluding value-added activities like machining or MRO. Certification is not legally mandatory but is a commercial requirement from OEMs and primes for supply chain approval, with 2,442 global certifications (836 in the U.S.) as of May 2023 enabling OASIS listing and market access.

Does **AS9120B** require an external audit or third-party certification?

**AS9120B requires third-party certification through accredited bodies for formal recognition in aerospace supply chains.** Organizations undergo Stage 1 (documentation review) and Stage 2 (on-site effectiveness audit) per IAQG rules, followed by annual surveillance and triennial recertification. Internal audits (Clause 9.2) provide ongoing evidence, but external certification demonstrates compliance to customers via OASIS.

How often should an assessment for **AS9120B** be performed?

**AS9120B requires internal audits at planned intervals to cover the entire QMS annually, with management reviews at least annually.** Clause 9.2 mandates an audit program ensuring objectivity, while Clause 9.3 requires management review inputs like performance trends, risks, and nonconformities. Frequency escalates for high-risk processes like traceability and supplier controls.

What are the consequences of non-compliance with **AS9120B**?

**Non-compliance with AS9120B risks exclusion from OEM supply chains, contract penalties, and supply chain safety liabilities.** Without certification, distributors face commercial disqualification, loss of OASIS visibility, and exposure to recalls from traceability failures or counterfeit parts. Audit findings trigger corrective actions; persistent issues lead to certification suspension.

An **AS9120B** be mapped to other international frameworks?

**AS9120B aligns directly with ISO 9001:2015 via its 10-clause high-level structure, enabling seamless integration.** It augments ISO requirements with aerospace additions, allowing organizations to map Clause 4-10 elements while justifying "not applicable" determinations (e.g., Clause 8.3 design) in the QMS scope without compromising conformity.

What is the first step to begin implementing **AS9120B**?

**The first step is conducting a gap analysis against AS9120B clauses using a cross-functional team to identify deficiencies.** Document internal/external context (Clause 4), justify scope/applicability (4.3), and prioritize risks like supplier controls and traceability, producing a risk register and implementation backlog.

What is the primary objective of **MLPS 2.0 (Multi-Level Protection Scheme)**?

**The primary objective of MLPS 2.0 is to establish a graded cybersecurity protection system ensuring security controls match the potential harm from system compromise to national security, social order, and public interests.** It classifies information systems into five levels based on impact severity, mandating commensurate technical, management, physical, and personnel controls per GB/T 22239-2020 and related standards.

Who is legally or professionally required to comply with **MLPS 2.0 (Multi-Level Protection Scheme)**?

**All network operators in mainland China must comply with MLPS 2.0 under Article 21 of the 2017 Cybersecurity Law.** This includes domestic enterprises, foreign-invested entities, cloud providers, and operators of IT, IoT, big data, or industrial control systems, regardless of size or sector.

Does **MLPS 2.0 (Multi-Level Protection Scheme)** require an external audit or third-party certification?

**Yes, MLPS 2.0 requires external security reviews by licensed Chinese firms for Level 2 and above systems, with PSB approval.** Reviews score compliance at least 75/100 across technical and management domains; Level 3+ demands annual evaluations.

How often should an assessment for **MLPS 2.0 (Multi-Level Protection Scheme)** be performed?

**Assessments under MLPS 2.0 must occur biennially for Level 2, annually for Level 3, semi-annually for Level 4, and as mandated for Level 5.** Re-evaluations are also required after major system changes.

What are the consequences of non-compliance with **MLPS 2.0 (Multi-Level Protection Scheme)**?

**Non-compliance with MLPS 2.0 results in fines up to 100,000 yuan, operational suspensions, system shutdowns, and intensified PSB inspections.** Severe cases link to business license denials or criminal liability.

An **MLPS 2.0 (Multi-Level Protection Scheme)** be mapped to other international frameworks?

**Yes, MLPS 2.0 control domains align with frameworks like ISO 27001 and NIST CSF.** Organizational, physical, and technical controls map directly, enabling gap analysis via Statements of Applicability.

What is the first step to begin implementing **MLPS 2.0 (Multi-Level Protection Scheme)**?

**The first step is conducting a provisional self-assessment to classify systems into one of five protection levels based on impact to national security and public interests.** Inventory assets and document rationale per GB/T 22240-2020 before PSB filing.
