EASA Part 21 – Design, Certification and Production

Part 21 regulates the approval of aircraft design and production organisations and the certification of aircraft Products, Parts and Appliances.

We help organisations seeking to obtain and maintain a Design Organisation Approval (DOA) or Production Organisation Approval (POA) to achieve:

  • Significant performance improvements resulting from a pro-active approach to managing certification and production
  • Reduced losses due to rework, delays, and product integrity
  • Improved organisational efficiency
  • Improved Regulator confidence
  • Reduced risk of liability

Challenges you might be facing

  • Balancing the demands of the regulator and client to deliver safe, compliant and cost-effective designs and products
  • Ensuring your design / production systems are compliant with all aspects of Part 21 while contributing to maximum business efficiency
  • Managing an effective certification plan to ensure robust and efficient demonstration of compliance to certification specification
  • Co-ordination of Design and Production functions
  • Identification and capture of requirements
  • Proactively ensuring that safety assessments and safety cases meet the intent of certification codes
  • Obtaining new approvals and maintaining existing approvals with minimum disruption to existing management systems
