The CAA collects, records and analyses all reports received under the Mandatory Occurrence Reporting Scheme (MORS), as detailed in CAP382.

The objectives of the CAA Mandatory Occurrence Reporting (MOR) Scheme are as follows:

a) To ensure that the CAA is advised of hazardous or potentially hazardous incidents and defects (occurrences).

b) To ensure that knowledge of these occurrences is disseminated so that other persons and organisations may learn from them.

c) To enable an assessment to be made by those concerned (whether inside or outside the CAA) of the safety implications of each occurrence, both in itself and in relation to previous similar occurrences, so that they may take or initiate any necessary action.

The overall objective of the CAA in operating occurrence reporting is to use the reported information to improve the level of flight safety and not to attribute blame.

The CAA receives approximately 10,000 new reports every year, all of which are entered onto the database.  The scheme has been running since 1976 and now contains over 150,000 records.

The MOR Scheme remains one of the most important safety data resources for the CAA and industry.
