The supreme discipline of aeronautical service provision

AeroImpulse – your competent partner for EASA approvals

Your advantage

With an official approval from the European Safety Agency (EASA) companies can not only deliver aircraft components, but also create the conditions for being a system supplier. With such official approvals companies can issue Approved Data or an EASA Form 1 and thus also place complex aviation components on the market. The three industrial standard approvals are those of the

  • Subpart 21/J for design organization,
  • Subpart 21/G for production organization,
  • Part 145 for maintenance organization.

Our Competence

AeroImpulse supports your organisation on the way to an EASA approval. Our customers profit in a unique way from our industry expertise and enthusiasm for aviation quality management: through years of project and certification experience, sound methodological knowledge and practical know-how gained from consulting and audits. We are the ideal partner if your organization is seeking an authority approval as an official aeronautical organization.

Your challenges

What’s the problem?

In Europe, the design, production and maintenance of aeronautical products is regulated by strict requirements of the European Aviation Safety Agency (EASA). For example, companies that want to operate on the market as independent companies require an operating license from EASA or the national aviation authority.

Gain expertise

In addition to the capacitive burdens, there is usually a lack of expertise. Familiarization with the EASA texts is laborious. Understanding, interpreting and implementing the legal texts in a practical manner almost always causes problems for companies with little or no experience in the aviation industry. This applies to the EASA regulations themselves (Implementing Rules and their subparts) as well as in particular to the important interpretation material (Guidance Material / Acceptable Means of Compliance – AMC), which is only available in English.

Create capacity

If your organization has applied for one of these approvals and the agency does not raise any fundamental concerns, you will have to overcome some hurdles in your quality management systems (see box). The implementation of EASA Approvals therefore means a complicated additional task for every QM representative over many months. In addition, processes must also be adjusted throughout the entire company and employees, as well as managers in particular, must be qualified for their new tasks.

Individual consulting

We have in-depth expertise in setting up rule-compliant and audit-proof quality management systems in the aviation industry. At the same time, we can provide you with comprehensive knowledge of the approval process according to Subpart 21J (Design), Subpart 21G (Production) or Part 145 (Maintenance).

Best possible preparation

We know the industry and we know the legislation of the European Aviation Safety Agency. We assist you reliably in obtaining an official approval – regardless of whether your company wants to operate as an approved design organization, production organization or maintenance organization. Our support includes consulting, auditing and training with the aim of optimal preparation for the approval audit by EASA or your NAA.


Benefit from comprehensive know-how transfer – cooperation with us is always qualification and training in the field of aviation legislation, the acceptable means of compliance (AMC) and the guidance material (GM), but also in terms of general quality management and methodological competence.

Auditing according to EASA Part 21 or 145

Audit is one of the fastest and most effective tools for identifying weaknesses in a quality system. However, its usefulness stands and falls with the auditor’s qualification. We support you in conducting aeronautical audits according to Part 21 or Part 145. Use our audits as a “dry run” for your approval audit or for ongoing vulnerability identification. Even after the initial audit, EASA and LBA require aviation-approved organizations to undergo regular audits, and we will be happy to assist you in this process. With qualified EN 9100 auditors who have sound knowledge of air law, we carry out first and/or second party audits (external supplier audits) competently with the necessary objectivity. We check or monitor the quality capability of your company or that of your key suppliers based on the EASA standard.

Accountable Manager / Form 4 Holder Coaching

Management staff  must be appointed by EASA or NAA as a Form 4 Holder. The appointment is only made after an official suitability interview in which the manager has to prove the professional suitability and the knowledge of the corresponding EASA part. The Accountable Manager and the so-called Form 4 holders or postholders (QM representative, development / production manager) are affected by this regulation. Especially for managers who have little in depth expertise of aviation legislation, the EASA interview is a challenge. We prepare your Accountable Manager or Form 4 holders for regulatory interviews through one-on-one or small group coaching sessions.

  • Introduction to aeronautical quality management,
  • Explanation of the regulatory requirement for certificated aeronautical operations,
  • Detailed examination of the specifications of the respective EASA Part,
