Sofema Online (SOL) considers the role and purpose of OSD.

Introduction Operational Suitability Data (OSD)

The European Commission published OSD requirements on 27 January 2014 requiring aircraft (and Helicopter) manufacturers, to submit data that EASA considers important for safe operations.

Operational Suitability Data (OSD)” means data, which are part of an aircraft type-certificate, restricted type- certificate or supplemental type-certificate, consisting of all of the following:

SofemaOnline (SOL) considers best practice related to the provision of an effective Maintenance Repair Organisation (MRO) / Continuing Airworthiness Management Organisation (CAMO) Aircraft Technical Library.


Strong Management of Technical documentation is an imperative for a well-run organisation. The effective administration of technical documentation and management of related aviation publications should never be overlooked and can adversely affect smooth-running and operational effectiveness if not managed to a high level.

The management of technical manuals and documents which are related to the establishment & maintenance of the aircraft, as well as to support the continued demonstration of organisation compliance with regulatory requirements is of critical importance to the success of the organisation.

General Introduction

The Maintenance Control Center (MCC) acts as an integrator of multiple elements bringing together key mission-critical oversight activities

The MCC may be co-located with the Operations Control Centre (OCC) or developed as a separate unit

It is usually expected that the operation control centre (OCC) is supported by the Maintenance Control Center (MCC) which not only controls aircraft maintenance activities, also provides interface & guidance for the outstations.

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;

Introduction by Sofema Online (SOL)

The following abbreviated notes provide a summary of the key events related to the EASA Type Certification Process.

Type Certification

 A type certificate is an approval made by a regulatory authority that an aircraft is manufactured according to an approved design, and that the design ensures compliance with airworthiness requirements.

• The type certificate (TC) implies that the aircraft is manufactured according to the approved design and can be issued an Airworthiness Certificate.
• To meet airworthiness requirements, the aircraft, related products (engine and propeller), parts, and appliances must be approved.
• Within the European Union (EU), implementation rules for type certification are laid down by the Commission Regulation (EU) No 748/2012 of 3 August 2012.

Note - A Type Certificate is not an Airworthiness Certificate.

Airlines perform aircraft maintenance in order to ensure aviation safety and schedule punctuality. Sitting alongside this is the desire to also perform efficiently, arranging the manpower to have the optimum level of competence requires a considerable effort to ensure that the availability matches the requirement.

Whilst the “almost” universal approach to large aircraft maintenance afforded by MSG 3 delivers the potential of a very effective task orientated maintenance program, the very real challenge presented to Planners is how to decide on the best way to package these task so that the most effective workscope may be compiled to align with the available maintenance capacity.

Within every company exists the balance between availability, utilisation and maintenance requirements to understand fully the criteria which is applicable and to make focused decisions becomes the key to optimising the cost of maintenance.
