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

**AS9120B establishes a quality management system (QMS) for aerospace distributors that procure, store, split, and resell parts without altering characteristics.** Built on ISO 9001:2015's 10-clause structure, it adds over 100 IAQG-specific requirements targeting distribution risks like traceability loss, counterfeit parts, documentation errors, and external provider weaknesses. Core focus: chain-of-custody integrity via operational controls in Clause 8 (traceability, preservation, configuration management, counterfeit prevention).

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

**AS9120B applies to stockist distributors, pass-through distributors, and those performing batch splitting in aviation, space, and defense supply chains.** It targets organizations reselling aerospace parts without modification; excludes value-added activities altering conformity or MRO. Certification is not legally mandatory but commercially essential—OEMs/primes require it for supplier approval, with 2,442 global certifications (836 U.S.) as of May 2023 enabling OASIS visibility.

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

**AS9120B requires third-party certification via accredited bodies using IAQG rules and AS9101 audit criteria.** Process includes Stage 1 (documentation review) and Stage 2 (on-site effectiveness audit), followed by annual surveillance and triennial recertification. Internal audits (Clause 9.2) support readiness, but external certification provides OASIS listing and market qualification.

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

**AS9120B mandates internal audits at planned intervals to cover the QMS annually (Clause 9.2).** Management reviews occur at planned intervals (typically quarterly), analyzing performance data, risks, audits, and supplier trends (Clause 9.3). External surveillance audits occur yearly post-certification, with full recertification every 3 years.

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

**Non-compliance with AS9120B risks contract disqualification, supply chain exclusion, and liability for safety incidents.** No direct legal penalties, but OEMs/primes impose it contractually; audit failures yield major nonconformities in traceability/counterfeit controls, leading to certification denial, OASIS delisting, recalls, and reputational damage.

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

**AS9120B aligns directly with ISO 9001:2015's high-level structure, enabling seamless mapping of its 10 clauses.** Clause-by-clause comparisons exist for integrated systems; aerospace additions (e.g., counterfeit prevention, traceability) augment baseline ISO requirements without conflict.

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

**Conduct a formal gap analysis against AS9120B clauses using cross-functional teams to map current processes.** Define QMS scope (Clause 4.3), justify "not applicable" determinations (e.g., 8.3 design), and prioritize distributor risks like supplier controls and traceability for a risk register.

What is the primary objective of **AS9110C**?

**AS9110C's primary objective is to enable aviation maintenance organizations to consistently provide products and services meeting customer and statutory/regulatory requirements while enhancing customer satisfaction through effective QMS application and continual improvement.** It incorporates ISO 9001:2015's Annex SL structure across Clauses 4–10, adding maintenance-specific controls like configuration management, product safety, counterfeit parts prevention, traceability, preservation, and human factors consideration to ensure continuing airworthiness.

Who is legally or professionally required to comply with **AS9110C**?

**AS9110C applies to aviation maintenance organizations, including repair stations and MRO providers, regardless of size or type, whose primary business involves maintenance or continuing airworthiness services.** This includes independent repair stations, airline maintenance departments, OEM MRO operations, and component overhaul facilities performing work on civil or military aircraft; certification is often contractually required by OEMs and regulators for OASIS listing and supply chain access.

Does **AS9110C** require an external audit or third-party certification?

**Yes, AS9110C requires third-party certification through accredited registrars, with initial Stage 1 (documentation review) and Stage 2 (on-site effectiveness audit) audits.** The QMS must be fully operational for at least three months, including a full internal audit cycle and management review, prior to certification; ongoing surveillance audits occur annually, with recertification every three years.

How often should an assessment for **AS9110C** be performed?

**Internal audits for AS9110C must be performed at planned intervals based on process risk, status, and importance, with full coverage at least annually.** Management reviews occur at predetermined intervals aligned with business cycles, using performance data from monitoring, audits, and nonconformities; critical processes like configuration management and release require higher frequency.

What are the consequences of non-compliance with **AS9110C**?

**Non-compliance with AS9110C risks loss of repair station approvals, contract ineligibility, regulatory sanctions, and safety incidents compromising airworthiness.** Certification lapses prevent OASIS listing and OEM contracts; operational failures in traceability or counterfeit prevention can lead to rework, AOG events, fines, litigation, and reputational damage from maintenance errors.

Can **AS9110C** be mapped to other international frameworks?

**Yes, AS9110C aligns directly with ISO 9001:2015 via its Annex SL high-level structure and shares terminology like "documented information" and "external providers."** IAQG correlation matrices facilitate mapping to regulatory frameworks such as FAA/EASA Part 145, enabling integrated QMS without exclusions where requirements are applicable within scope.

What is the first step to begin implementing **AS9110C**?

**The first step is to define QMS scope, determine internal/external issues, and conduct a gap analysis against Clauses 4–10 using IAQG checklists.** Secure executive sponsorship, map regulatory approvals and customer requirements, and justify any non-applicable clauses to establish boundaries before process design and risk assessment.
