Airworthiness Directives (ADs) are issued to address unsafe conditions.
Aircraft on the UK Register are required to comply with applicable UK ADs, European Aviation Safety Agency (EASA) ADs and those issued by the National Authority of the
State of Design. Links to other NAAs websites are listed further down.
Prior to July 2003, UK ADs for UK Products were a number only linked to a CAA declared Mandatory Service Bulletin
issued by the Type Certificate Holder. If you have the SB you have the AD. These AD and SB Numbers are listed in
CAP 476, which is current at final issue (September 2004) and no longer
amended. Those Service Bulletins remain mandatory under EU ;regulations, unless cancelled and/or superseded by
a new AD.
Mandatory Requirements issued by the CAA for non-EASA products of UK Design or CAA ADs for EASA products
issued under Article 14(1) of Regulation (EC) No. 216/2008 are available for download from the website until they
are published in CAA publication CAP 747.
