Sofema Aviation Services (SAS) Considers the importance of managing the risks in a systematic and controlled way, using a Risk Register as the Fundamental Tool.

Hazard identification is the foundation of the risk management process in an SMS and may be conducted reactively, proactively, and even predictably. A Hazard is something with the potential to cause harm, and a risk is the potential outcome of a hazard.

What is the difference between a Safety System Hazard Register and a Risk Register?

Sofema Online (SOL) considers the function of evaluation board and operational suitability data related to FAA & UK CAA Type Certification.

Introduction UK CAA Evaluation Process

The UK CAA system (derived from EASA) includes, under the type certification process, an approval of data that are considered necessary for the safe operation of an aircraft, called the Operational Suitability Data (OSD).

» These data, once approved, are attached to the TC through a reference in the TCDS and owned by the TC holder.

Presentation by SofemaOnline (SOL) -

Visual inspection is an essential part of airplane maintenance.

The visual inspection component of NDI requires trained and experienced inspection personnel, using validated procedures and appropriate calibration standards with effective, well-maintained equipment in a well-managed maintenance environment.

Visual inspection is defined as the process of using the eye, alone or in conjunction with various aids, as the sensing mechanism from which judgments may be made about the condition of a unit to be inspected.

Considerations for the availability of supporting EASA Part 145 Maintenance courses delivered online through our virtual aviation academy.


EASA Part 145 and its forebear JAR 145 is a mature regulatory environment with nearly 30 years of development within the European Arena.

There is the increasing focus being brought to bear regarding the importance of managing competence within the workplace and it is for the reason that both EASA & European Regulatory Authorities are expecting that EASA Part 145 Organisations manage the competence of employees within the 145!

Sofema Online (SOL) looks at best practice to ensure optimum Aircraft Zonal Inspection within your Organisation.

Consider the following reasons, which have been understood to impact the Inspection process and to also provide an insight as to why Inspection Does NOT “Always” Identify the Problem:

- Visual Inspection is typically 80% of all inspection activities
- Visual Inspection forms a vital part of the many available Non Destructive Inspection (NDI) techniques
- Visual inspection is of the greatest importance to aviation reliability, for airframes, power plants and systems.
- Performed correctly it can detect a variety of defects, from cracks and corrosion to loose fasteners, ill-fitting doors, wear or stretching in control cables as well as damaged components.

Brief Overview of the fundamentals of an EASA Part 145 approval provided by SofemaOnline (SOL)


EASA Part 145 and introduces a uniform set of requirements for organisations providing maintenance services, including both work on aircraft and related to aircraft parts to be released to service.

To perform maintenance and to issue a certificate of release to service on either Complex Motor Powered Aircraft CMPA or Aircraft operated as Commercial Air Transport (CAT) on either an aircraft or aircraft part registered in a country member of the European Union or of EASA, the maintenance organisation must be PART 145 approved.

Review by Sofema Aviation Services (SAS)


The role of Aircraft Maintenance Inspector is without any doubt a complex task during which the inspector is required to visually search for multiple defects occurring at varying severity levels and differing locations, some of which may be difficult to reach or to achieve a comfortable position.

As aircraft age they are naturally more susceptible to defects and as a consequence typically require more intensive inspection programs.
