Structures Transmission and ICA group

The Structures Section (C.2.1)

The general subject areas addressed by Structures Section are:

  • Loads (e.g. aerodynamic, inertial, cabin pressurisation, fuel pressure, thermal and control system)
  • Static strength
  • Fatigue and damage tolerance
  • Aeroelastic stability
  • Materials and manufacturing processes
  • Crashworthiness
  • Impact related requirements such as bird strike, engine and tyre debris

In relation to this domain the Structures Section:

  • Undertakes certification tasks and ensures continued airworthiness of aeroplanes, rotorcraft and other products, parts and appliances as required, in conjunction with the project certification teams,
  • Interacts in certification and other processes with many other sections, in particular: hydromechanical systems, transmission, continued airworthiness, MRB, cabin safety, powerplant installation and flight,
  • Participates in the development of new airworthiness requirements, including relevant parts of Certification Specifications and advisory and guidance material in co-operation with the EASA Rulemaking Directorate,
  • Supports EASA research activities, accident investigation, organisation approvals and standardisation tasks including accreditation of NAAs and Qualified Entities,
  • Provides advice on structures topics within EASA and externally to Industry, Academic Organisations, Governments and their NAAs.

The Transmission Section (C.2.11)

The Transmission Section:

  • Undertakes certification and validation activity relating to new helicopter transmission designs,
  • Ensures continued airworthiness of helicopter transmissions following in-service events,
  • Contributes to the development of transmission related regulations in CS 27 and  CS 29,
  • Supports EASA research activities, accident investigation, organisation approvals and standardisation tasks including accreditation of NAAs and Qualified Entities,
  • Provides advice on transmission related topics within EASA and externally to Industry, Academic Organisations, Governments and their NAAs.

The Instruction for CAW & Maintenance Training Section (C.2.13)

The Instruction for CAW & Maintenance Training Section deals with certification activities related to the Instructions for Continued Airworthiness (ICA) and Operational Suitability Data (OSD) for Maintenance Training (MT).

The Instructions for CAW & Maintenance Training Section:

  • Performs the relevant certification steps for ICA and OSD for MT
  • Liaises with other disciplines’ experts, (as the ICA compliance is typically a multi-working-body activity)
  • Conducts evaluations to ensure suitable OSD for maintenance training are established including the determination of type rating and minimum syllabus of type rating training for maintenance certifying staff
  • Participates in the development of new airworthiness requirements, including relevant parts of Certification Specifications and advisory and guidance material in co-operation with the EASA Rulemaking Directorate
  • Provides advice ICA and OSD for MT topics within EASA and externally to Industry, Academic Organisations, Governments and their NAAs

Relevant Certification application forms are available under the Application Form page.
