Safety Information Bulletin 

CASA is responsible under the Civil Aviation Act for promoting safety and security in the civil aviation system by providing safety and security information and advice and fostering safety and security information education programmes, and promoting full and effective consultation and communications with all interested parties on aviation safety issues.

A CASA Safety Information Bulletin (SIB) is an information tool that intends to alert, inform and draw the attention of the aviation community on safety issues.

SIBs contain non-mandatory information and guidance that do not qualify for an Airworthiness Directive (AD). SIBs may be potentially used on any type of aviation safety related subject for which CASA has received information and that it finds useful to share with the aviation community for the sake of safety promotion. Non-exhaustive examples of cases where a SIB can be issued include: - information related to suspected unapproved parts - information related to falsification of licenses - design, production or maintenance related information and /or recommendations that do not meet the criteria for an AD - flight operations related information and/or recommendations, including to address risks arising to civil aviation from conflict zones (RCZ) - ATM/ANS related information and/or recommendations - reacting to Safety Recommendations issued by Safety Investigation Authorities addressed to CASA.
