A key element of any State Safety Programme now requires the oversight of numerous safety KPIs. None more important than aircraft maintenance reliability, since there is a direct impact on owner/operator safety. In simple terms, regulators are required to demonstrate reliability oversight as a basic fundamental to their safety obligations. Air transport the world over is having to deal with increasingly complex operational & technical systems, not least integrated Safety Systems in an extensive environment of reducing cost and increasing competitive advantage. Reduced aircraft maintenance reliability, also means reduced aviation safety performance for the state (as well as the operator), which can have critical impact on the nation as whole, and may include –
Higher exposure to aviation incidents & accidents at the national level;
Diminished reputation for safety and reliability on the global stage;
Operational restrictions placed on registered aircraft outside of sovereign borders.
To this end, aircraft maintenance reliability is considered as one of the major requirements by National Aviation Authorities (NAA) and should be treated as an intrinsic element of the State Safety Programme (SSP). Therefore, the NAA’s ability to maintain a clear oversight of Aircraft Maintenance Reliability in the Commercial Air Transport domain is critical to the national and international success of the state.
Reliability programs form an essential element of the continuing airworthiness process and in fact, is mandatory when aircraft are managed using Maintenance Steering Group or Condition Monitoring maintenance programme methodologies. As a regulator, you will be introduced to the concept and the purpose of a reliability program, not only to ensure that the aircraft maintenance program tasks are effective and their periodicity is adequate, but also to ensure that aircraft maintenance is performed in a safe manner utilizing all safety reliability data available to it.
Additionally, the reliability program may result in the escalation or deletion of a maintenance task, as well as the de-escalation or addition of maintenance tasks. As the regulator, you will need to understand if and when to approve such amendments by investigating and analyzing reliability data presented by your operators with a view to the approval of changes to their aircraft maintenance programmes.
Who is the Course for:
This intensive 2 Days course is specifically aimed at regulatory personnel who are involved in the review and determination of approval of reliability programmes. In particular, regulatory professionals with responsibility for approval of new aircraft maintenance reliability functions, as well as consideration for approval of amendments to existing systems, not least those professionals involved with the achievement of an effective interface between the operator’s reliability functions and the concerned departments within the National Aviation Authority.
What is the benefit of the training – what will I learn?
a) Understand the importance of Aircraft Maintenance Reliability within the context of safety and the remit of the SSP.
b) Expectations from your Owner / Operator of aircraft.
c) Assessment and decision-making of proposed reliability systems (Initial Application / Amendment)
d) Reliability Centred Maintenance equals Safety Centred Maintenance
e) Supporting Subpart G Reliability related Continued Airworthiness Management (CAM) organizations in terms of changing regulatory and operational environment – How to support your operators and keep them compliant.
f) Reviewing, assessing and reporting on overall reliability at the state and international level – What the regulator needs to be doing.
