Part 21 Continued Airworthiness Obligations

TR24M02 | 2 days

Continued Airworthiness is a frequently used term in EASA Part 21, but not defined. The military (under the equivalent EMAR21) does describe it as “all tasks to be carried out to verify that the conditions under which a type certificate or a supplemental type certificate has been granted continue to be fulfilled at any time during its period of validity (Type Design)”. However, even that does not fully describe the scope of obligations associated with the term. It might be easier to think of Continued Airworthiness as the postcertification airworthiness obligations and requirements which Design Approval Holders (i.e. Design Organisations) and Production Organisations have under EASA Part 21.

How will this course benefit me?

Ideally combined with TR14 (or its EMAR equivalent in TR80) or TR24M01 (or its EMAR equivalent in TR81M01), this module takes a practical approach to providing the necessary insight to ensure the intelligent adoption of the regulatory intent behind the Continued Airworthiness requirements, which are currently distributed across:

  • Part 21 Subpart A (e.g. 21.A.3 to 21.A.4)
  • Part 21 Subpart B (e.g. 21.A55, -57, -61 & -62)
  • Part 21 Subpart D (e.g. 21.A.105, -107, -108)
  • Part 21 Subpart E (e.g. 21.A.119 & -120)
  • Part 21 Subpart M (e.g. 21.A.447 &-449
  • Part 21 Subpart O (e.g. 21.A.609 & -613

Using industry experience and examples of best practice, you will explore these key elements of Part 21 so that you will not only be able to ensure your organisation is fully compliant, but also that compliance is achieved within a system which is fully integrated into the culture and management system(s) of the organisation.

Completing this course will ensure you understand:

  • Your Voluntary and Mandatory Occurrence Reporting Obligations (including those in EU376/2014) and how this is dependent on the successful accomplishment of a Just Culture how the Design Organisation (DO) interfaces with Production (and Maintenance Organisations) to ensure parts fitted to aircraft are both safe and conform to design data (these are 2 distinctive obligations which require close collaboration)
    Your obligations to support EASA in the issue of ADs and how this relates to Service Bulletins (SB) and Safety Information Bulletins (SIB). For DO attendees, the last 2 hrs of this session will provide you with the knowledge/tools required to substantiate the AD compliance time (or rectification period)
  • The DO’s obligations when it comes to:
    • Manuals and Instructions for Continued Airworthiness (ICA)
    • OSD and their amendments
    • Record Keeping.


Is this course right for me?

This practitioner level course is specifically designed for:

  • Design and Productions Organisations who all need to comply with EASA or EMAR Part 21 Subpart A.
  • Design Organisations who need to comply with the requirements regarding Manuals, ICA, OSD and Records

Note: Production Organisations need only attend the morning session.
Individuals in the following positions would benefit from a comprehensive understanding on how the Continued Airworthiness obligations influences their daily responsibilities:

  • Head of Design and/or Production
  • Office of Airworthiness (incl. Certification Managers)
  • Compliance Verification Engineers and Certifying Staff
  • Independent System Monitors (incl. Quality Assurance)
  • Design and Production Managers and Team Leaders


This course would also benefit:

  • National Aviation Authority Managers, including Military Airworthiness Authorities adopting
  • Accountable Managers, who are ultimately accountable for DOA and POA performance
  • Programme Managers responsible for scheduling design and production activities
  • Approved Maintenance (Part 145) organisation who do prototype installations for Design Organisations


Pre-requisites:A prerequisite for the course is a fair level of understanding of:

  • The Quality/Production Management System in Subpart G (POA). See TR14 or TR80
  • The Design Assurance/Management System in Subpart J (DOA). See TR24M01 or TR81M01
  • It is expected that DO representatives on this course would have read AMC21.A3B and AMC25.1309(b) carefully before the course to benefit from the discussion to simplify it.
