I’m trying to determine how “RAA” (RA-Aus) became implicated in this post, given the accident occurred in the UK as a likely result of a component made and purchased in the USA 🤔….
In any event, I was informed by my CASA Authorised Person that it was not their job to determine the airworthiness of any experimental aircraft, nor could they deny a Special CoA, even if the aircraft was built out of Clag, paddle pop sticks and Bunnings bolts.
CASA will issue a AC21-4 Special Certificate of Airworthiness (Experimental) but the restrictions placed upon the aircraft as a result of their risk assessment (Test area, Phase 1 duration etc) may make it impractical.
