Cabin Safety Design- Certf. of Interior Changes & Repairs - Large Aeroplanes


This 3-day training course will provide the necessary knowledge to the participants how to classify and certify Large Aeroplanes Cabin Interior Design Changes & Repairs. Relevant for staff at all levels within Design Organisations, with or without an EASA Design Organisation Approval, as well as Civil Aviation Authorities in third countries (Non-EASA member States).

The content of the training course is based on the assumption that a so-called “green aircraft” exists with all necessary structural and systems interface provisions available in the cabin needed for the installation of the change.

Classification of interior changes, minor/major/significant will be addressed in detail and relevant CS-25 paragraphs will be discussed and practical examples, e.g. STCs, will be reviewed.

Course Content

The following subjects will be addressed:

  • Introduction: Overview of the training course
  • EASA
  • The legal and regulatory basis for the EASA EU Member States
  • Explanation of all relevant Annex I (Part 21) Subparts, e.g. Subpart A, Subpart D, Subpart E, Subpart K, Subpart M, Subpart P and Subpart Q amended with Operational Suitability Data Requirements, Flight Test Operations Manual, Categories of Flight Tests and Flight Test Staff Qualifications
  • Overview and detailed explanation of the relevant CS-25 paragraphs out of Subpart C (Structure) - Subpart D (Design & Construction) - Subpart F (Equipment) - Subpart H (EWIS) which may require a showing of compliance
  • Examples of actual executive cabin interiors certified by EASA, e.g. Supplemental Type Certificates
  • Practical examples of stretcher and galley testing
  • Review and discussion of interesting EASA Special Conditions (Certification Review Items, CRI’s) applicable to executive cabin interiors approved by EASA

Learning Objectives

At the end of the training course the attendees should have the capability to classify changes to cabin interiors into minor, major or significant, identify applicable CS-25 paragraphs and have a general understanding of the Means of Compliance with these requirements.

Who should take this course

Design (engineering)organizations having an EASA Design Organisation Approval (DOA) or considering to apply for such an approval. The training is of importance to the management of such organizations, e.g. Head of the Design Organisation, Chief Independent System monitoring and Chief Office of Airworthiness, as well as engineering staff, Office of Airworthiness staff and Compliance Verification Engineers (CVE).

The training is also valuable to Civil Aviation Authorities of third countries, e.g. non EASA Member States, when these Authorities intend to implement the relevant EU legislation regarding aviation safety or wanted to become more knowledgeable in order to approve cabin interior design changes developed by airlines or maintenance organizations in these countries.


Some knowledge regarding Annex I Part 21 and CS-25, Certification Specifications for Large Aeroplanes, is an advantage but not necessary.implement or have already implemented national legislation based on Annex I (Part 21).


3 days, starting each day at 9:00 hrs and ending each day at 17:00 hrs.

NOTE: Participants should bring a laptop since some of the course material is provided on USB sticks.
