An occurrence associated with the operation of an aircraft which, in the case of a manned aircraft, takes place between the time any person boards an aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time as it comes to rest at the end of the flight and the primary propulsion system is shut down, in which:
(1) a person is fatally or seriously injured as a result of:
(a) being in the aircraft, or
(b) direct contact with any part of the aircraft, including parts which have become detached from the aircraft, or
(c) direct exposure to jet blast, except when the injuries are from natural causes, self-inflicted or inflicted by other persons, or when the injuries are to stowaways hiding outside the areas normally available to the passengers and crew; or
(2) the aircraft sustains damage or structural failure which adversely affects the structural strength, performance or flight characteristics of the aircraft, and would normally require major repair or replacement of the affected component, except for engine failure or damage, when the damage is limited to a single engine (including its cowlings or accessories), to propellers wing tips, antennas, probes, vanes, tyres, brakes, wheels, fairings, panels, landing gear doors, windscreens, the aircraft skin (such as small dents or puncture holes), or for minor damage to main rotor blade, tail rotor blades, landing gear, and those resulting from hail or bird strike (including the radome); or
(3) the aircraft is missing or completely inaccessible.
An incident involving circumstances indicating that there was a high probability of an accident and is associated with the operation of an aircraft, which in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time it comes to rest at the end of the flight and the primary propulsion system is shut down.
Accidents and serious incidents involving Isle of Man registered aircraft which have occurred in the UK, a UK Overseas Territory or a Crown Dependency are investigated on our behalf by the UK Air Accidents Investigation Branch (AAIB). To report such events please contact the UK Air Accidents Investigation Branch.
- 24-hour reporting line - Telephone: +44 1252 512299
Accidents and serious incidents involving Isle of Man registered aircraft which have occurred in other countries are primarily investigated by the local accident investigation authority. Contact information is available from the International Civil Aviation Organisation.
Regardless of the location of the event, a Form 30 Occurrence Report must be completed and submitted to the Isle of Man Aircraft Registry no later than 72 hours following discovery of the accident or serious incident.
For further information see Registry Publication 5 - Occurrence, Serious Incident and Accident Reporting.
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 objectives of both Mandatory and Voluntary Reporting are the:
- prevention of accidents and incidents and not to attribute blame or liability;
- to contribute to the improvement of air safety by ensuring that relevant information on safety is reported, collected, stored, protected and disseminated.
For further details of Mandatory and Voluntary 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 72 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.
SAFETY DATA AND INFORMATION PROTECTION
Preventative, corrective or remedial action, may necessarily be taken by the aircraft operator and/or the IOMAR for the purposes of maintaining or improving safety.
- Preventive action is an action taken to prevent the occurrence or recurrence of an event or a hazard that poses a risk to safety.
- Corrective action is an action taken to address particular safety-related shortcomings or deficiencies, such as an authorisation holder who is unable to demonstrate compliance with applicable safety or competency standards. Corrective action may be necessary to bring an authorisation holder back into compliance.
- Remedial action is an action taken to address the underlying causes of particular safety-related shortcomings or deficiencies, such as training. Remedial action might also involve restricting, limiting, suspending or revoking the privileges of an authorisation, certificate or licence holder who fails to continue to meet the necessary qualifications to exercise those privileges.
These actions are not to be regarded as punitive or disciplinary but are necessary to prevent or minimise the exposure to an unmitigated safety risk;
