Like it or not, the holiday season will end. Facts are incontrovertible. The UK and EU have just a few months to finish a Withdrawal Agreement. This is to allow for scrutiny and ratification in both the UK and the EU’s 27 Member States. A Withdrawal Agreement must be signed in October and that’s just days away.
Let’s look at one more civil aviation issue. The continuing airworthiness of a civil aircraft is dependent on the exchange of information between authorities and organisations across the globe. This is flow of information is practically improved if working arrangements or bilateral agreements exist between Countries. These are built on mutual interest, trust and a long-established familiarity with each other’s regulatory systems.
Yes, the duties of Countries under their obligations as signatories of the Convention on International Civil Aviation, dated 7th December 1944 (known as the “Chicago Convention”) exist but these are the basics and even then, those basics are often given scant regard.
In the 1970s, some European civil aviation authorities started to co-operate to produce common “Joint Airworthiness Requirements.” Even before the 1990 Cyprus arrangement in Europe, both the US and European authorities had been working to harmonise rules and reduce duplication of regulatory activities.
Today, a mature EU-US bilateral is in place. So, if a British manufacture wishes to export an aviation product to the US it can do so with relative ease. As per Subpart G 21.A.163 of Commission Regulation 748/2012, the holder of a production organisation approval may issue authorised release certificates (EASA Form 1) without further showing. That EASA Form 1 is then recognised in the US.
The Treaty’s Article 50 clock stops at the end of March 2019. It’s reasonable to ask the question; what Authorised Release Certificate will be used in the UK after that date and will it be recognised?
All the loud yah-boo politics, so loved of Westminster, doesn’t offer an answer.
NOTE 1: The EASA Authorised Release Certificate is known as the EASA Form 1.
NOTE 2: The FAA Authorised Release Certificate is known as the FAA Form 8130 -3, Airworthiness Approval Tag.
