Definition of an 'Occurrence'
“Occurrence” means an operational interruption, defect, fault or other irregular circumstance that has or may have influenced flight safety and that has not resulted in an accident or serious incident;
The objective of both Mandatory and Voluntary Reporting is to contribute to the improvement of air safety by ensuring that relevant information on safety is reported, collected, stored, protected and disseminated.
The sole objective of occurrence reporting is the prevention of accidents and incidents and not to attribute blame or liability. This applies to occurrences that endanger or that, if not corrected, would endanger an aircraft, its occupants or any other person.
For further details of Mandatory Reporting please see Registry Publication 5 - Occurrence, Serious Incident and Accident Reporting.
Reporting of occurrences
In the event of an Occurrence, which endangered or which, if not corrected, would endanger an aircraft, the occupants or any other persons, must be reported to the Isle of Man Aircraft Registry within 96 hours using Form 30 Occurrence Report.
If any reporter considers that it is essential that their identity not be revealed, the report itself should be clearly annotated 'CONFIDENTIAL' and submitted directly to ‘Director of Civil Aviation’' and the envelope should be marked 'Personal'.
The request will be respected and the reporter will be contacted personally, either by the Director of Civil Aviation or their deputy.
Confidentiality cannot, of course, be guaranteed when an occurrence is reported separately by another party or in respect to gross negligence, wilful violations or destructive acts.
Reporters submitting a Confidential Report must also accept that effective investigation may be inhibited, however, the IOM CAA would rather have a Confidential Report than no report at all.
