AS9110C Details
What It Is
AS9110C is the SAE/IAQG quality management system standard for aviation maintenance, repair, and overhaul (MRO) organizations, building on ISO 9001:2015 with aerospace-specific requirements. Its primary purpose is ensuring safe, compliant maintenance through risk-based thinking, configuration control, and traceability. It uses the High Level Structure (HLS) and PDCA cycle.
Key Components
- Clauses 4-10 covering context, leadership, planning, support, operation, evaluation, improvement.
- Aviation additions: counterfeit parts prevention, human factors, product safety, continuing airworthiness.
- Over 100 requirements with documented information for evidence.
- Certification via accredited registrars with Stage 1/2 audits.
Why Organizations Use It
- Meets customer/OEM contracts and regulatory alignments (FAA/EASA Part-145).
- Mitigates safety risks, reduces rework, improves on-time delivery.
- Enhances market access via OASIS listing, builds stakeholder trust.
- Drives efficiency and competitive edge in MRO sector.
Implementation Overview
Phased approach: gap analysis, process mapping, training, internal audits, certification. Applies to all MRO sizes globally; requires 3+ months operational data pre-certification. Involves eQMS, auditor training, PDCA cycles.
ISO 27018 Details
What It Is
ISO/IEC 27018 is a code of practice extending ISO/IEC 27002 for protecting personally identifiable information (PII) in public clouds where providers act as PII processors. Its primary purpose is to provide cloud-specific privacy controls, focusing on processor obligations in multi-tenant environments through a risk-based approach layered on an ISO 27001 ISMS.
Key Components
- Core themes: consent/purpose limitation, transparency, data minimization, subcontractor management, logging/auditability, breach notification, secure deletion.
- ~25-30 additional privacy controls aligned with ISO/IEC 29100 principles.
- Builds on ISO 27002:2022's 93 controls; no standalone certification—assessed within ISO 27001 audits with updated Statement of Applicability.
Why Organizations Use It
- Demonstrates robust PII safeguards for cloud customers, aiding GDPR/CCPA alignment and vendor due diligence.
- Enhances risk management, reduces procurement friction, builds stakeholder trust via certifications (e.g., Drata, Vanta).
- Competitive edge for SaaS/cloud providers in regulated sectors.
Implementation Overview
- Conduct gap analysis on existing ISO 27001 ISMS, layer privacy controls, automate monitoring via GRC tools.
- Applies to cloud PII processors of all sizes; involves policy updates, tooling (e.g., SIEM, CSPM), third-party audits annually.
