Audit Scheduling
An essential requirement of our audit program is to cover the entire organizational system, notionally this should be done on an annual basis, we should also be mindful that some areas may require more frequent auditing, whilst some areas may be audited on a less frequent basis.

The primary reason to perform audits is to ensure regulatory compliance with external requirements and full compliance with internal organizational requirements. The secondary reason is to enable an understanding of opportunities to seek out improvement.
Audits should never appear as adversarial or confrontational, rather they are a method which should be fully supported by the auditee to demonstrate compliance in all necessary areas.

Over the years there have been a number of in-flight smoke and fire events where contaminants ignited by electrical faults allowed the fire to be sustained and spread. The FAA and the National Transportation Safety Board (NTSB) have conducted aircraft inspections and found wiring contaminated with items such as dust, dirt, metal shavings, lavatory waste water, coffee, soft drinks, and napkins. Sometimes wire bundles and surrounding areas have been found to be completely covered with dust.
In recent years both the FAA & Industry have realized that current maintenance practices may not be enough to address aging non-structural systems. Over time, insulation can crack or breach, thus exposing the conductor.

EWIS Stands for Electrical Wiring Interconnect System and it is an abbreviation for something which has been around a long time. In fact any wiring, even a single wire may be considered as EWIS.
Training related to Electrical Wiring Interconnect System (EWIS) was introduced by European Aviation Safety Agency (EASA) in August / September 2008. The details were to be found in 3 Acceptable Means of Compliance (AMC) documents, specifically AMC 20-21, AMC 20-22, AMC 20-23.
EWIS is Mandatory training requiring both Initial and Recurrent elements with details of the identified groups being detailed in AMC 20-22.

Without Doubt the above subjects are very important in respect of the need to manage competence within both the Maintenance Management and Maintenance Delivery Environment recognizing improvement in the need to ensure competence. EASA mandated in February 2010 the need to ensure competence within the CAMO workplace. Commission Regulation (EU) No 127/2010 | EASA

This was amplified in 2011 when EASA again issued specific regulations associated with the management of competence ED Decision 2011-011-R - EASA - Europa
Maintenance Planning is a function of the Continuous Airworthiness Management Organization (CAMO) and both SAS and SOL offers a broad range of courses ranging from a single day to a 5 days integrated training.
Production Planning is an Essential function of the EASA 145 organization and provides a structure whereby the effective management of maintenance delivery process may be correctly coordinated and managed.
Technical Records is actually required for both the CAMO organization (Belonging to the Operator) and for the 145 organization (Belonging to the Maintainer).

It is accepted within our aviation community, that the vast majority of aviation accidents (at least 80%) are directly caused by human action or more precisely by human error. However it would be wrong for us to assume that this is simply a manifestation of personal carelessness or even incompetence, rather we should try to consider that the human error itself is actually the final element of a chain of events.

In fact a major element which hitherto was not given sufficient consideration is the role of the organisation in aircraft incidents and accidents. Often the root cause or contributing factors are embedded within the organisations process and procedures. Unfortunately with hindsight we are often able to understand the existence of numerous latent “exposures” (sometimes too late!).

What do we mean by Root Cause? Often people have a bias to stopping at an event, which itself has enables or causes, however with practice it becomes easier to work through the process and achieve meaningful results.

Let’s take some time to De-Mystifying Root Cause, when we talk about Root Cause we are simply trying to understand why a “something” has happened – what where the fundamental causes and on the journey to discover as many of the contributing factors as we can.

So the focus is on “Why” and “How” a particular event or condition occurred so that we can develop the correct understanding.

Ensuring that we ensure compliance with the highest standards of Aviation Safety, is a responsibility which is shared between manufacturers, operators, regulators and MRO (Maintenance Repair Organisations) or Aviation Maintenance organisations, but note that each organisational element has specific obligations to ensure compliance with all regulatory obligations.

We understand that the aviation maintenance environment is heavily regulated this is true in fact whether the activity is delivered in the Middle East, Europe, America or the Far East.

Over the years we have seen a steady improvement in the technical safety of aircraft, however the potential exposure introduced by the human element remains ever present and needs to be addressed in the best way possible.

SofemaOnline features European Aviation Safety Agency (EASA) & Gulf Civil Aviation Authority (GCAA) selection of Technical Terms to be found in Aircraft Technical Records

Part 2: Check – GVI – DVI – SI
An examination (e.g., an inspection or test) to determine the physical integrity and/or functional capability of an item.

GVI - General Visual Inspection is the “Basic Inspection” which is usually performed without removing panels (other than quick release).
DVI - Detailed Inspection requires additional activity which will be identified within the task.
SI - Special Inspection will also be identified typically relates to Non Destructive Testing (NDT).

SofemaOnline ( features European Aviation Safety Agency (EASA) & Gulf Civil Aviation Authority (GCAA) selection of Technical Terms to be found in Aircraft Technical Records.

Part 1 Airworthiness Directive

An Airworthiness Directive or AD is issued when there is a problem with the aircraft which MUST be resolved. AD are issued only by the Regulatory Authority – Federal Airworthiness Authority – FAA or EASA or CAA (Civil Aviation Authority) Compliance with AD’s is mandatory!

Airworthiness Limitation Item

An Airworthiness Limitation or (ALI) is issued after the design analysis has been carried out. So they are typically available at the delivery of the very first aircraft. Compliance with ALI’s is also mandatory.

SofemaOnline ( features European Aviation Safety Agency (EASA) & Gulf Civil Aviation Authority (GCAA) Aircraft Technical Records

What are Aircraft Technical Records?

At first it might seem obvious. However as we dig a little deeper we uncover a set of rules and regulations which describes exactly what we mean by both Aircraft Technical Records as well as Aircraft Continuing Airworthiness Records. Typically Part M/CAR M Requirements relate to Continuing Airworthiness Records and Aircraft Records primarily relate to Part 145/CAR 145. However there are difference to discuss and in addition there are other Aircraft Technical Records which are relevant to either the CAR/Part M organisation or the CAR/Part 145 Organisation.

Considerations related to the delivery of Safety Systems

Where is your organisations current focus? Is it on compliance or Performance?

This is a significant question because whilst compliance is of course mandatory it is through performance related developments that we are able to optimise and drive significant savings within the organisation, whilst at the same time ensuring we deliver a safe and effective business environment.

Where does safety come from?
People or Procedures?

Well simply implementing process and procedure is not in itself going to provide an effective solution to the needs of the organisation.
We rely on people to deliver our safety management system and this in turn requires a specific and viable organisational culture and senior led behaviour.

Last modified on presents - The Role of the EASA Airworthiness Review Certificate (ARC)

Considerations to support the understanding of the role of the EASA Airworthiness Review Certificate ARC.


Effective 29th September 2007 - All aircraft used for Commercial Air Transport have been subject to the full requirements of Part M.
ARCs are valid for 12 months. Before your ARC expires, you need to ensure that a new ARC is issued or that the current is extended in order to allow legal flight to continue.

In accordance with Part M of Regulation (EC) 1321/2014, all EASA aircraft types that qualify for an EASA Certificate of Airworthiness (CofA) are issued with a non-expiring CofA, validated annually with an Airworthiness Review Certificate (ARC).

The European Commission published amendment 1056/2008 Regulation (EC) 2042/2003 on 29 October 2008. The changes in the amendment introduce new rules and new categories of aircraft that are affected by Part M.

FTS owes its origins to the analysis following the in-flight break up of Flight TWA 800 in July 1996. The origins of EWIS in fact go back a lot further but did not take on a formal identity until August 1996 when a White House Commission under the directorship of vice president Al Gore was set up.

EWIS & FTS is a Recurrent training which is applicable to many employees within both the Operator Part EASA M environment and MRO EASA Part 145 environment. offers a 2 Day Industry Specific EWIS – FTS online Initial and Recurrent training to ensure your employees have a full understanding of issues concerns and best practices to ensure they remain fully compliant with EASA regulatory requirements.

SofemaOnline is developing a portfolio of online training courses written by professionals with many years of experience.

Here we look at techniques to support an effective Aviation Quality Assurance Audit and the way we ask questions during an audit, to enable us to take the maximum benefit from the responses we receive.

For the most effective outcome the Auditor should remain in control of the process from start to finish. The auditor has (or should have) the full attention of the Auditee and must ensure that you understand the responsibility to obtain the information necessary to make the correct determinations.

So how are we going to ask questions, in such a way that we quickly get to the substance of what we are trying to audit?
Although we ask questions of each other all day long we seldom consider which technique works best and how we may improve our questioning skills.

Aviation Human Factors training has only been mandatory for the last 10 years with the EASA compliant maintenance environment.

Why Aviation Human Factors Training?

Well currently some 80% of aircraft accidents are attributable to human error, shared between pilots, maintenance staff and Air Traffic Control, Ground Operations and a very small percentage to other factors.

In the main it should be understood that this is a situation which is recognized as rectifiable through the process of raising awareness, training including the associated management of competence and implementation of effective process and procedure and effective communication within the workplace.

In order to ensure a smooth transition and a high level of civil aviation safety in the European Union, Implementing Rules should reflect the state of the art, including best practices, and scientific and technical progress in the field of air operations. Accordingly, technical requirements and administrative procedures agreed under the auspices of the International Civil Aviation Organization (hereinafter referred to as “ICAO”) and the European Joint Aviation Authorities (hereinafter referred to as “JAA”), as well as existing European and national rules, should be considered.

The introduction of Part OPS Regulation 965/2012 was a huge undertaking pulling together not only Commercial Air Transport – CAT but all the different arrangements related to operation of aircraft including Commercial other than Non Commercial, Helicopter, Aerial Work and other Specialist Services.
