Airworthiness Bulletins

An Airworthiness Bulletin (AWB) is issued to inform the aviation public, in a systematic way, of essential information not considered mandatory. The information contained in an AWB is for information only, and issued by CASA to disseminate information as quickly and as clearly as possible.
