Where can I find more information on the Working Arrangement on Airworthiness Certification (WA-AC) between the European Union Aviation Safety Agency (EASA) and CAAS?
The WA-AC establishes a reciprocal arrangement between the two organisations to validate and accept each other’s design certifications and approvals of aircraft parts, aircraft modifications and repairs. In addition, Design Organisation Approval (DOA) holders will no longer need to hold duplicate CAAS and EASA Approvals to operate in both Singapore and Europe. The number of regulatory inspections will be reduced, resulting in time and cost savings for the aviation industry on both sides. Air operators and other industry stakeholders from both Europe and Singapore will benefit from this arrangement. More information on the WA-AC can be found in Advisory Circular AC 21-5(0).
