Sofema Aviation Services (SAS) considers the key elements of the MSAT Tool

The EASA MSAT Issue 2 represents a paradigm shift from compliance-focused oversight to a holistic, performance-driven model. It challenges both authorities and operators to go beyond minimum requirements, embedding resilience, risk-awareness, and continuous improvement into everyday operations.

By embracing MSAT, the aviation community can achieve stronger safety performance, greater operational consistency across Europe, and ultimately, safer skies for all.

Introduction

The EASA MSAT is a structured methodology developed to support both competent authorities and aviation organisations in assessing the effectiveness and maturity of management systems (MS) across aviation domains.

Rooted in ICAO Annex 19 principles, EASA MSAT embraces the 12-element SMS framework while aligning with EU regulations such as Regulation (EU) 376/2014 on occurrence reporting. Its aim is to move beyond a compliance-driven model towards a performance-based oversight (PBO) approach, fostering continuous improvement and positive safety culture across the European aviation landscape.

MSAT provides a common assessment language that facilitates:

Consistent performance evaluations across different domains (e.g., Part-CAMO, Part-145, Part-21),
Integration of multiple approvals into a single management system assessment,
Alignment with international agreements and harmonised oversight for organisations holding multiple certificates.

The Issue 2 update (September 2023) integrates lessons learned, updates from ICAO and EASA publications, and inputs from both industry and competent authorities. It’s a maturity model, not a checklist, guiding the evaluation of management system elements as Present, Suitable, Operating, or Effective (PSOE).

Key Operational Features of the EASA MSAT

Applicability Across Domains and Organisation Types:
- Adaptable for use by competent authorities (for oversight) and organisations (for self-assessment or gap analysis).
- Scalable for organisations of any size, complexity, and operational profile, with guidance on suitability and scalability.
- Customisable to specific domain requirements (e.g., CAMO, Maintenance, Design, ANSPs).
PSOE Maturity Levels:
- Present: Documented within the MS.
- Suitable: Appropriate to the organisation’s size, complexity, and risk profile.
- Operating: In active use, producing results.
- Effective: Achieving desired safety outcomes, driving continuous improvement.
Integrated Framework:
- Combines ICAO SMS pillars (Safety Policy & Objectives, Risk Management, Assurance, Promotion) with EASA-specific requirements (e.g., compliance monitoring, just culture).
- Encourages interface management across integrated approvals (e.g., CAMO & OPS).
Assessment Approach:
- Not a compliance checklist, but a performance-oriented, risk-based tool.
- Inspectors and organisations use “what to look for” guidance—interviews, document reviews, observations—to evaluate maturity, effectiveness, and culture.
- Focus on safety outcomes, risk management capabilities, and system resilience.
Oversight Integration:
- Supports initial certification, continuing oversight, and performance-based oversight (PBO).
- Allows competent authorities to extend oversight cycles for mature organisations demonstrating strong safety performance (per ARO.GEN.305(c)).
- Considers credit from other oversight activities (audits, occurrence investigations).
Interface with Other Standards:
- Aligns with ICAO SSPIA, SMICG tools, European Just Culture Declaration, and relevant EASA domain-specific AMCs/GM.
- Accommodates multiple certificates and regulatory frameworks.
Feedback and Continuous Improvement:
- Competent authorities are required to provide feedback to EASA (per EPAS MST.0026) for ongoing refinement of the tool.
- Promotes a collaborative approach between authorities, industry, and EASA.

How Regulatory Authorities and Operators Should Engage with MSAT

For Competent Authorities:

Use MSAT as a core tool in initial certification and continuing oversight:
- For new applicants, confirm MS processes are Present and Suitable.
- For existing approvals, ensure MS is Operating and moving towards Effectiveness.
Adopt a performance-based oversight model:
- Move beyond compliance audits to evaluate maturity, risk management capability, and safety outcomes.
- Apply PSOE levels to assess the organisation’s progress and effectiveness.
Foster a collaborative relationship:
- Engage organisations in open dialogue about their MS, encouraging proactive improvement.
- Share observations (not just findings) to promote continuous learning.
Integrate assessments across multiple domains where appropriate, ensuring consistent messaging and coordinated oversight between different authorities.
Use MSAT outcomes to inform oversight planning, including the potential extension of cycles for mature organisations.
Invest in assessor training:
- Ensure assessors are competent in risk- and performance-based assessment, the PSOE model, and the tool’s practical use.
- Promote knowledge sharing and harmonisation across oversight teams.

For Operators and Organisations:

Use MSAT as a self-assessment and improvement tool:
- Evaluate your MS across the PSOE maturity levels.
- Conduct gap analyses during implementation or integration of new approvals.
- Engage proactively with the competent authority—share your MSAT assessment, fostering a common understanding of system maturity.
Prepare for assessments by:
- Ensuring management system processes are documented, resourced, and suitable.
- Demonstrating how the MS operates in practice through evidence (e.g., reports, records, staff interviews).
- Focusing on continuous improvement, identifying areas for enhancement, and addressing findings and observations effectively.
Engage in open dialogue with the authority:
- Discuss suitability, scalability, and performance objectives.
- Address interface management, especially when holding multiple approvals or working with subcontractors.
Invest in safety culture:
- Promote a positive safety culture and just culture principles, ensuring staff understand their roles and feel safe to report.
- Use MSAT as a guide for embedding safety into the organisation’s DNA.
