SofemaOnline looks at the challenges related to the potential uncertainty of the status of instructions for continued airworthiness (ICA) and needs, therefore, to avoid there being too much room for interpretation in the rules and standards, leading to differences and possible safety risks.

The specific objective is to establish clear requirements and responsibilities for all parties involved in the production of ICA, their approval and their implementation.

The Notice of Proposed Amendment (NPA) proposes to amend Annex I (Part 21) of Regulation (EU) No 748/2012 to clarify that ICA are part of the type certificate (TC) and to develop the related acceptable means of compliance (AMC) and guidance material (GM).

It also merges the requirements related to record-keeping, manuals and ICA in the various subparts into a single requirement for each of these aspects in Subpart A (new points 21.A.5, 6 and 7).

SofemaOnline takes a looks at NPA 2018-11

The objective of this Notice of Proposed Amendment (NPA) is to improve the level of safety related to the minimum syllabus of maintenance certifying staff (MCS) type rating training (TRT), enabling design approval holders (DAHs) that comply with Annex I (Part 21) of Regulation (EU) No 748/2012 to identify the technical elements necessary to be addressed for the purpose of training of maintenance certifying staff involved in the maintenance of their products.

In addition, the intent is to ensure an adequate minimum syllabus standard at organisations that comply with Annex IV (Part-147) to Regulation (EU) No 1321/2014.

This NPA proposes:

The first issue of Certification Specification on Maintenance Certifying Staff (MCS) data (CS-MCSD) and the associated Guidance Material (GM);

It is important to ensure that all employees are aware of how to act in the event of a workplace emergency. Whilst not every person needs to be qualified as a fire marshal or Emergency First Aid Responder, it is important that a number of employees are "highly trained" and all employees have an general awareness of all potential emergencies and how to proceed.

All employees should understand what constitutes an emergency or disaster at the workplace?

SofemaOnline takes a deep dive into Root Cause Analysis (RCA)

Introduction - What Do We Mean when we talk about "Root Cause"?

This is the first challenge and typically causes must confusion across the business with some people believing there is always a “single” root cause to a particular issue or problem.

In fact, as we will quickly see there can indeed be multiple root causes associated with a single problem.

The purpose of the Root Cause Analysis is to understand the causal factors that contribute to a particular event.

Introduction to Hazards & Risk 

Hazard - Consider that a Hazard has the potential to disrupt or cause harm in some way - this does not in any way mean that it will - simply it can.

Risk - When we look at risk we are trying to determine how great is our exposure to the perceived hazard. So risk is subjective and the more effective the risk analysis and mitigation process the less likely we are to suffer the consequence of a “hazard”.

Reality Check 1 - Maintenance professionals are of course human and therefore prone to human error. Therefore acceptance of vulnerability and potential exposure is the first step in taking responsibility and avoiding risk-taking behaviours.
