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.

(*) from 1 June 2019, all other pilots subject of airspace infringement MORs are contacted by the CAA to notify them of their airspace infringement and a pilot report requested. Once the investigation is complete, and if an airspace infringement is confirmed, the pilot will be sent a warning letter to close the occurrence.

Casual factor analysis
Annual reports are 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 UK Civil Aviation Authority: 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.
