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.

The purpose of this Safety Notice is to highlight causal factors associated with recent loss of control accidents, specifically aircraft system knowledge and technical competence in dealing with multiple system malfunctions combined with possible unexpected flight control inputs, during a period of cognitive degradation associated with ‘surprise and startle effects’.

Version 2: This reflects an update to the Applicability for Flight Operations to 'All AOC Holders'.
