Operational Suitability Data (OSD) Introduction
Sofema Online (SOL) www.sofemaonline.com introduces Operational Suitability Data.
Introduction & Regulatory Drivers for OSD
With the entry into force of Commission Regulation (EU) No 69/2014 on 18 February 2014 the concept of Operational Suitability Data (OSD) was implemented, integrating operational evaluation elements into the certification design process as foreseen in the Basic Regulation1. Available operational suitability data are then referenced in the applicable Type Certificate Data Sheet (TCDS).
OSD Transition from OEB
Commission Regulation (EU) No 69/2014 introduces Article 7a of Commission Regulation (EU) No 748/2012.
Paragraph 3 of Article 7a states: "Operational Evaluation Board reports and master minimum equipment lists issued in accordance with JAA procedures or by the Agency before the entry into force of this Regulation [18 February 2014] shall be deemed to constitute the operational suitability data approved in accordance with point 21.A.21(e) of Annex I (Part 21) and shall be included in the relevant type-certificate. Before 18 June 2014 the relevant type-certificate holders shall propose the Agency a division of the operational suitability data in mandatory data and non-mandatory data."
Additional Guidance Article 7a of EU 69/2014

» The approval shall be obtained not later than 18 December 2015 or before the aircraft is operated by an EU operator, whichever is the latest.
» The operational suitability data may be limited to the model which is delivered.
Elements of OSD controlled under Design Organisation Approval
» Classification
» Design Investigation
» Showing of Compliance
» Approval
» Distribution
» All controlled under Part 21
Classification of a Change
A change is defined as any deviation from the approved design.
» Supplemental Type Certificate
» Repair
» Modification
All changes in design need to be approved.
» Changes consist of Design Data and Compliance Data (OSD is part of this definition)
Note Similar to ICA, OSD contains both design and compliance data.
