Airworthiness Notices are issued by the Civil Aviation Authority to circulate
information to all concerned with the airworthiness of civil aircraft. Mandatory
Airworthiness Notices that were previously published in CAP 455 have been
transferred to CAP 747 – Mandatory Requirements for Airworthiness and are now
published as Generic Requirements in Appendix 1. This document can be located via
