SofemaOnline takes a look at the importance of Aircraft Technical Records within the context of Aircraft Leasing


When an aircraft has significant disconnects in the integrity of the records the value of the aircraft can be substantially affected. (Any lapses in maintenance documentation can be used as financial leverage). Airlines routinely spend up to $2000,000 USD related to narrow body returns and the majority of lease return costs relate to disconnects in the aircraft technical records.

The Value of an Aircraft equal is Technical Records?

Well, when you consider that without the Technical Records which support the aircraft it will not be able to fly then it is effectively a true statement!

SofemaOnline takes a look at what SMS Internal Reporting Elements should be addressed in the context of the Organisational 145 SMS 

Reporting Systems should include the possibility of Voluntary and Confidential Elements, however, please note that an essential feature of a successful system is the willingness of the Employees to engage with the system. In fact, this becomes a key measure of an effective system.


The overall purpose of the internal safety reporting scheme is to use the reported information to improve the level of the safety performance of the organisation, and not to attribute blame.

The scheme is an essential part of the overall monitoring function and should be complementary to the normal day-to-day procedures and ‘control’ systems; it is not intended to duplicate or supersede any of them.

SofemaOnline takes a look at what SMS related Change Management Processes are coming into EASA 145 Management Systems 


Unless they are properly managed, changes in organisational structure, facilities, the scope of work, personnel, documentation, policies, and procedures, etc. can result in the inadvertent introduction of new hazards and expose the organisation to new or increased risk.

Effective organisations seek to improve their processes, with conscious recognition that changes can expose the organisation to potentially latent hazards and risks if they are not properly and effectively managed.

Comment by Steve Bentley CEO of 

Quality Assurance is considered as a subset of SMS. Is this correct? 

What does EASA Say? 

These key safety management processes are supported by a compliance monitoring function as an integral part of the management system for safety.

Most aviation safety regulations constitute generic safety risk controls established by the ‘regulator’. Therefore, ensuring effective compliance with the regulations during daily operations and independent monitoring of compliance are fundamental to any management system for safety.

The compliance monitoring function may, in addition, support the follow-up of safety risk mitigation actions.

Sofema Aviation Services looks at what is coming related to EASA Part 145 Management System 


EASA objective is to encourage organisations to embed safety management and risk-based decision-making into all their activities, instead of superimposing another system onto their existing management system and governance structure.

The new elements that are introduced by the NPA 145 in particular address component 2 ‘Safety Risk Management’ of the ICAO SMS framework. and address component 3 ‘Safety Assurance’.

It is important to recognise that safety management will be a continuous activity, as hazards, risks and the effectiveness of safety risk mitigations will change over time.
