SofemaOnline (SOL) considers best practices related to the management of Recurrent Defects within the Maintenance Control Centre

Introduction - How To Ensure That Outcomes Of Repeated Defect Analysis Provide Meaningful Results

Maximization of fleet availability depends in part on having the ability to identify potential repeating defects on either individual or fleet aircraft and to expedite the necessary maintenance action.

» Being able to identify such repeating defects is dependent on a number of  variables

o   Has the defect been correctly recorded into the reliability system?

o   Can we rely on Engineering to ensure that outcomes of repeated defect analysis provide meaningful results?

Sofema Online (SOL) takes a look at the process to ensure effective control of “Aircraft On Ground” (AOG’s) & Unscheduled Maintenance


Significant losses are suffered due to AOG’s and unscheduled maintenance, across industry tunning to many millions of Dollars.

» Losses Occur primarily due to the non-availability of aircraft resulting in lost revenue.
» Parts & Materials ordered on an AOG basis are typically charged at a premium rate.

SofemaOnline (SOL) considers the best practices needed to ensure effective management of Technical Documentation within the Maintenance Control Centre


Strong Management of Technical documentation is imperative for a well-run Maintenance Control Centre. Administration of technical document management should never be overlooked and can adversely affect smooth-running and operational effectiveness if not managed to a high level.

To support efficiency & safety we should ensure that we have the most appropriate systems and processes in place that can help support all associated business areas.

SofemaOnline (SOL) considers the communication relationship between the Maintenance Control Centre (MCC) and the Airline Operations Control Centre (OCC)

Introduction – Considering OCC Functions

The goal of any OCC is to be efficient, effective and promote best practice decision making- To make the best decision for the right reasons (Based on the optimum data set available)

The development of an OCC is a continuous process usually driven by either a shortfall in expected outcome (driven by an ineffective process) or the internal need to improve a process which whilst compliant with the objective no longer meets acceptance.

SofemaOnline (SOL) considers primary aspects of FAA Certification including aircraft & repairs.

Introduction - How Does the FAA Certify Aircraft?

The FAA collaborates with the International Civil Aviation Organization and other civil aviation authorities to maintain and advance the safety of international air transportation.

The Certification Process involves the following:

» A review of any proposed designs and the methods that will be used to show that these designs and the overall airplane complies with FAA regulations;
» Ground tests and flight tests to demonstrate that the airplane operates safely;
» An evaluation of the airplane's required maintenance and operational suitability for introduction of the airplane into service;

SofemaOnline (SOL) looks at evaluating the benefits of implementing a Maintenance Control Centre.


A major advantage of cost-benefit analysis lies in forcing people to explicitly and systematically consider the various factors which should influence strategic decisions, using the cost-benefit analysis process we are able to drive more critical thinking around all aspects of the project value.

Note Cost-benefit analysis assumes that a monetary value can be placed on all the costs and benefits of a program, including tangible and intangible returns.

Sofema Online (SOL) considers the process of developing an Aviation Maintenance Control Centre from an existing EASA compliant Continuing Airworthiness Management Organisation (CAMO) operation

Introduction - What’s in a MCC?

»  All the elements of Maintenance Control are to be found within Part M of the regulations (however the reverse statement is not true)

To consider the contents of Part M, in particular, Part M Subpart C as an appropriate starting point.

A review carried out by Sofema Online (SOL)


As with the majority of organizational elements to be found within the MCC the key is to build on the basic understanding of what functions the MCC will perform.

An early decision relates to the decision whether to co-locate the Maintenance Control Centre (MCC) with the Operations Control Centre (OCC). When both units are co-located the organisations report more effective communications and improved coordination during emergencies and AOG Situations.

Sofema Aviation Services (SAS) considers the need and regulatory drivers and understand why are required for existing repairs and changes.


What is the rationale for DTE and DTI of repairs and changes?

Essentially it is related to the possibility of Early Fatigue or Fails safe requirements (pre 25 571 Amdt 45) which did not necessarily provide for timely inspection of critical structure so that damaged or failed components could be dependably identified and repaired or replaced before a hazardous condition developed.

Measuring the effectiveness of your company's quality system should be an essential element of the management of your overall quality management system strategy.

The process starts with a review of the organizational QMS policy together with a detailed gap analysis to assess full compliance with all regulatory obligations.

Having established regulatory compliance a further measure for assessing the strength of QMS is to employ a formal “internal” compliance audit process which will be set against an expected organisational standard.

With the exception of EASA Part 21 Subpart J Design Organisation Approval which as you will be aware is managed directly by EASA.

The process for all other approvals (Air Carrier – Part 145 / Part M / Part 147 / Part 21 Subpart G POE / ATO) is managed by the Competent Authority.

Essentially works as follows:
