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

**AS9110C** establishes quality management requirements for aviation maintenance organizations to ensure safe, compliant MRO services meeting customer and regulatory needs. It integrates **ISO 9001:2015** with sector-specific controls like configuration management, counterfeit prevention, and risk-based thinking to support continuing airworthiness and enhance customer satisfaction through traceable processes and continual improvement.

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

**AS9110C** applies to MRO organizations performing maintenance on commercial, private, or military aircraft, including repair stations and OEM MRO divisions. Certification is often contractually required by airlines, OEMs, and regulators like FAA/EASA for supplier qualification and OASIS listing, though not universally legally mandated.

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

**Yes, AS9110C** mandates third-party certification by accredited registrars via Stage 1 (documentation review) and Stage 2 (implementation audit) processes. Ongoing surveillance audits occur annually, with recertification every three years, requiring evidence of operational QMS effectiveness including internal audits and management reviews.

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

**Internal audits for AS9110C** must be conducted at planned intervals based on process risk, with critical maintenance processes audited more frequently. Management reviews occur at least annually or tied to business cycles, while external surveillance audits happen yearly post-certification, and full recertification every three years.

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

**Non-compliance with AS9110C** risks contract loss, exclusion from OEM supplier lists, regulatory sanctions like FAA/EASA Part-145 suspension, fines up to $100k daily, litigation from safety incidents, and revenue impacts from AOG events or rework, as seen in cases with multimillion-dollar shutdowns.

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

**AS9110C** aligns directly with ISO 9001:2015 via shared HLS clauses and maps to aviation regulations like FAA/EASA Part-145 using IAQG correlation matrices. It supports integrated management with standards like ISO 45001 for safety, avoiding duplication while addressing MRO-specific mandates.

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

**The first step for AS9110C implementation** is securing executive sponsorship and conducting a clause-by-clause gap analysis mapping existing processes to standard requirements, including regulatory alignments. This produces a prioritized gap register and phased SOW to prevent scope creep.

What is the primary objective of **ISO 27018**?

**ISO 27018 provides a code of practice for protecting personally identifiable information (PII) in public cloud environments where providers act as PII processors.** It extends **ISO 27002** controls with cloud-specific privacy guidance, emphasizing processor obligations like purpose limitation, transparency, and secure deletion to support controllers under frameworks like GDPR Article 28.

Who is legally or professionally required to comply with **ISO 27018**?

**No organizations are legally required to comply with ISO 27018, as it is a voluntary code of practice.** It is professionally adopted by public cloud service providers and SaaS vendors acting as PII processors to demonstrate robust privacy controls, particularly those handling customer PII in multi-tenant environments and seeking competitive differentiation or regulatory alignment.

Does **ISO 27018** require an external audit or third-party certification?

**ISO 27018 does not offer standalone certification but is assessed during ISO 27001 audits by accredited bodies.** Auditors evaluate its additional ~25-30 privacy controls within the existing ISMS, with inclusion in the Statement of Applicability; providers like Drata and Vanta publicly reference their ISO 27018-aligned certifications.

How often should an assessment for **ISO 27018** be performed?

**ISO 27018 controls should be assessed annually through surveillance audits as part of the ISO 27001 cycle, with full recertification every three years.** Continuous monitoring via GRC tools, CSPM, and SIEM ensures ongoing effectiveness, addressing dynamic cloud configurations and the 2025 edition's transition requirements.

What are the consequences of non-compliance with **ISO 27018**?

**Non-compliance with ISO 27018 results in loss of certification credibility, procurement disadvantages, and heightened privacy breach risks rather than direct legal penalties.** Organizations may face customer churn, failed due diligence, or indirect regulatory scrutiny under laws like GDPR, as it undermines processor assurances in data processing agreements.

Can **ISO 27018** be mapped to other international frameworks?

**Yes, ISO 27018 maps directly to ISO 27001, ISO 27017, and ISO 27701 via shared controls in ISO 27002:2022.** Tools leverage CSA Cloud Controls Matrix for alignment with GDPR, SOC 2, and HIPAA; GRC platforms like Drata and Vanta enable cross-mapping for multi-framework compliance.

What is the first step to begin implementing **ISO 27018**?

**The first step is conducting a gap analysis of existing ISO 27001 ISMS against ISO 27018's privacy controls.** Identify applicable PII processing activities, update the Statement of Applicability, and deploy tooling for continuous monitoring of cloud configurations, logging, and vendor management.
