UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

This SD is made in the interests of continued safety of operation and to protect the public following a serious incident on 20 February 2021 involving a United Airlines Boeing 777 aeroplane, Flight 328, where the right-hand engine failed in flight following a suspected fan blade failure. A similar engine failure occurred to a Japanese Airlines Ltd Boeing 777 on 4 December 2020.

This SD has been revoked as of 28 April 2021 as its purpose will be achieved through compliance with the mandatory requirements of associated FAA Airworthiness Directives before further operations are conducted with these aeroplanes.
