CAA Airspace Infringement Team decisions
The number of MORs processed each month do not correspond numerically to those reported in the same month due to the time taken to collate MOR, pilot and supporting supplementary reports.

Casual factor analysis
Latest report
This report details root causes and contributory factors of airspace infringements to provide information and help increase knowledge and awareness. It has been written by the CAA’s Airspace infringement Team who had access to Mandatory Occurrence Reports/Alleged Breach of Air Navigation Legislation Reports for all reported occurrences, and over 1,000 pilot reports, for reported airspace infringements in 2023.
Past reports
These reports were produced by a sub-group of the Civil Aviation Authority’s Airspace Infringement Working Group (AIWG). The group currently includes three people, all independent of the CAA: two industry experts whose experience covers microlight flying and instruction, higher performance commercial and IFR flying and instruction alongside a third member with experience in SEP flying and PhD level work in causal factors.
