Sofema Online (SOL) Takes a Deep Dive into MEDA Best Practices Developing effective and corrective actions is the ultimate goal of any MEMS investigation. The MEDA process is specifically designed to facilitate this by having investigators, typically using the MEDA Results Form, uncover the why behind the error- the contributing factors. Issues and Concerns in…

Sofema Online (SOL) considers the key aspects related to achieving the best outcomes with Boeing MEDA. Introduction  The Boeing Maintenance Error Decision Aid (MEDA) is a structured process developed to identify the contributing factors to maintenance errors and events, with the goal of developing effective prevention strategies.  Its core philosophy is that people don’t intentionally make errors, and most…

This white paper discusses the crucial elements, challenges, and best practices for integrating Maintenance Event Decision Aid (MEDA) into an organisational safety culture, effectively measuring its processes, and linking it to a robust Continuous Improvement cycle within a Safety Management System (SMS) 1. How to Embed MEDA into an Organisational Safety Culture Embedding MEDA into…

Sofema Aviation Services (SAS) looks at the implications of Latent & Active Failures related to MEDA Investigations. Definitions (simplified) Active Failures: Front-line deviations that directly precede the event-slips, lapses, mistakes, or rule violations at the point of work (e.g., step omitted, wrong torque, cross-mated connector). Latent Conditions: Hidden system weaknesses that sit in the background…
