Letīs complicate it even more. Whatīs Export C of A?
Seriously, whatīs the difference other than the obvious inclusion of the word "Export" on the certificate? What it takes, needs, include not usually asked for a regular C of A? Why have I heard that it could take as long as three months getting one (and not exactly for a 747)? Should a different one be written for the airframe, the engine and the propeller (all Iīve seen are for parts: engines or props, not for complete airplanes)?
Illuminate us, oh great Oaklandīs Oracle!
