Sofema Aviation Services (SAS) examines Risk Disassociation in EASA Part 145, highlighting key features, compliance points, and oversight checks.

Introduction

Risk disassociation is a critical challenge in EASA Part 145 organizations, as decision-makers who are not directly exposed to maintenance risks may struggle to fully appreciate their consequences. By implementing structured risk engagement mechanisms, immersive training, direct exposure initiatives, and strong communication frameworks, Part 145 organizations can ensure that those making decisions relate to, understand, and mitigate operational risks more effectively – Consider the following elements:

Understanding Risk Disassociation

Risk disassociation refers to the phenomenon where individuals making decisions about risks are disconnected from the actual exposure to those risks. In an EASA Part 145 Maintenance Organization, this is particularly relevant, as senior management, planners, and engineers who approve work may not be directly involved in the hands-on maintenance activities where hazards are present. This can lead to underestimation or misjudgment of risks, affecting safety and compliance.

Key Features of Risk Disassociation in Part 145

  1. Distance from Operational Reality
    • Senior decision-makers (e.g., Accountable Manager, Engineering Directors) may have limited direct exposure to day-to-day maintenance risks.
    • Supervisors or planners may not fully appreciate the risks encountered by frontline technicians.
  2. Incomplete Risk Perception
    • Those approving procedures, schedules, or resource allocations may not fully comprehend the impact of fatigue, environmental conditions, tooling limitations, or procedural complexity.
  3. Compliance vs. Practicality Gap
    • A procedure may be compliant with EASA regulations but impractical or unsafe in real-world application due to unanticipated operational constraints.
  4. Reactive Rather Than Proactive Risk Management
    • If decision-makers do not recognize risks before incidents occur, safety measures may be applied reactively rather than proactively.
  5. Safety Culture Disconnect
    • A strong safety management system (SMS) is critical, but if there is a disconnect between leadership and the workforce, the effectiveness of risk mitigation measures can be compromised.

Special Checks to Mitigate Risk Disassociation

To ensure decision-makers understand and relate to the risks, EASA Part 145 organizations should implement the following special checks:

  1. Enhanced Hazard Identification and Reporting
  • Encourage frontline technicians to report real-time hazards and unsafe conditions via a Just Culture environment.
  • Use digital platforms for real-time reporting, ensuring management receives unfiltered safety feedback.
  1. Direct Risk Exposure for Decision-Makers
  • Require senior personnel to conduct periodic on-the-ground risk observations in maintenance environments.
  • Implement a Job Shadowing Program, where managers and planners spend time in the hangar or line stations with technicians.
  1. Practical Risk Awareness Training
  • Conduct Risk Perception Workshops using real-life case studies.
  • Utilize virtual reality (VR) or simulation-based training to immerse decision-makers in high-risk maintenance tasks.
  1. Scenario-Based Risk Assessment
  • Perform What-If Analysis (WIA) exercises where management must respond to hypothetical safety scenarios.
  • Use bowtie analysis and failure mode effect analysis (FMEA) to evaluate how risk perception affects decision-making.
  1. Engaging Technicians in Risk Management Processes
  • Include frontline maintenance staff in risk assessment and procedural review meetings.
  • Establish risk communication channels where technicians can directly convey operational concerns to decision-makers.
  1. Cross-Functional Safety Reviews
  • Require multi-level participation in safety audits and risk assessments.
  • Use risk review boards with a mix of management and operational staff.
  1. Risk Visualization Tools
  • Implement risk dashboards that graphically represent hazards and near-miss trends.
  • Utilize digital tools to display risk heat maps that illustrate areas of concern in the maintenance process.
  1. Review of Risk-Related Decisions
  • Conduct post-decision safety audits to verify whether changes in procedures, schedules, or work instructions have led to unforeseen risks.
  • Use human factors evaluation to analyze how decisions impact maintenance execution.
