The principal procedure is the Mandatory Occurrence Reporting scheme which the Civil Aviation Authority (CAA) established in 1976. Its objectives are to ensure that the CAA is advised of any hazardous, or potentially hazardous, incidents and defects (occurrences), and that appropriate action is taken. All reports are disseminated to the relevant specialists in CAA. The Head of the Aviation Health Unit will see any where health effects are reported.
Should an individual wish to bypass his employer in reporting an incident, a separate procedure exists whereby details can be sent to the Confidential Human Factors Incident Reporting Programme.
