Introduction to certification in aviation

Certification in aviation is essential — it ensures safety by complying with applicable regulations and standards. Many companies start innovating and only later realise that certification requires significant time and resources. By understanding requirements early and aligning your design and processes with the standards from the start:

  • You avoid delays in market entry and unnecessary capital-intensive development iterations.
  • You build a strong intellectual property position early, increasing your attractiveness to investors.
  • You increase your professional credibility, which improves stakeholder confidence and your chance of success.
  • You find the right partners and advisors sooner.

Who needs certification?

Not only aircraft manufacturers!

Organisation type Examples Type of certification
Design organisations OEMs, start-ups, modifiers Design Organisation Approval (DOA)
Production companies Airframe, components, interiors, suppliers Production Organisation Approval (POA) and/or AS9100
Maintenance organisations MROs, line maintenance, overhaul Maintenance Organisation Approval (Part-145)
Component suppliers Avionics, engine parts, composites Material & process testing + supplier approvals
Test & measurement companies Wind tunnels, battery labs Accredited test certificates
Flight test organisations Flight test centres, prototype testing teams Approved Test Organisation (ATO) / Flight Test Operations approval
Note: In some cases, suppliers may operate under the certification framework of their customer, meeting the customer’s quality requirements. This approach can accelerate the certification process for newcomers.

Certification at a glance

A simple overview of the typical path from idea to a certified aviation product or organisation.

💡

Idea & Concept

Map the use case and early safety assumptions. Identify which approvals may apply (EASA/ILT).

🧪

Design & Testing

Align your design with applicable requirements. Plan verification & validation (analysis, ground/flight tests).

📄

Application

Submit your application with evidence (plans, conformity, test results) to the competent authority.

🔎

Audit & Inspection

Authority reviews, audits and inspections for compliance (processes, product, operations).

Certificate

Certificate granted. Continuous oversight applies to keep privileges (changes, surveillance).
