In accordance with the [[Convention on International Civil Aviation]] all aircraft must be registered with a national authority (such as the [[Federal Aviation Administration]] or [[Transport Canada]]), and furthermore, they must carry proof of this registration in the form of a legal document called a '''Certificate of Registration''' at all times when in operation. Most countries also require the aircraft registration to be imprinted on a permanent fireproof plate mounted on the [[fuselage]] for the purposes of post-fire/post-crash aircraft accident investigation. {{-}} {{Transport-stub}} [[Category:Aviation licenses and certifications]]
